Perimeter Center office frontage, Roswell Road retail, loading docks, compactor pads and structured parking, cleaned with the wash water contained and the tenants told before the crew arrives.
Thrare Contracting cleans exterior surfaces for commercial property managers, asset managers, facility directors and retail operators in Sandy Springs: office buildings around Perimeter Center, medical office buildings on the Pill Hill corridor, shopping centers and standalone retail along Roswell Road, mixed use blocks near City Springs, and the loading docks, service yards and structured parking that sit behind all of them. Sandy Springs is a service area rather than a company location. Rare Earth Ltd trades as Thrare Contracting, dispatches crews from the Atlanta address printed at the foot of this page, and was formed on January 19, 2020.
Rare Earth Ltd is registered in SAM under UEI Z4WKS4UE8NJ6 with CAGE 9JAV8, uses E-Verify, carries DBE, ACDBE and MBE certification, and qualifies as a small disadvantaged business. Rare Earth Ltd holds no HUBZone, 8(a) or SOC 2 status, and this website claims none of the three. Every one of those registrations can be checked by a buyer without calling this office, which is the point of listing them rather than describing the company as qualified.
Residential exterior cleaning and apartment community work are separate scopes with separate scheduling problems. A Sandy Springs apartment community is covered on the apartment pressure washing page for Sandy Springs, which deals with resident notice, amenity decks and elevator buildings. This page is written for a commercial asset where the people affected by a wash are tenants under a lease and customers walking to a door.
A commercial exterior wash turns on five decisions, and a bid that answers only the surface area has answered one of them.
A commercial address inside the Sandy Springs city limits is governed by the City of Sandy Springs, not by Fulton County. Fulton County states the boundary in its own words: "The purpose of the Stormwater Management Program is to manage the surface water resources of unincorporated Fulton County, including administration, maintenance, operations, regulation, and enforcement. For all other areas of the County, stormwater management is the responsibility of the individual cities" (Fulton County Government, Stormwater Services, read 2026-09-02). A contractor who hands a Sandy Springs board a Fulton County guidance sheet has handed them the wrong document.
The City of Sandy Springs runs its storm sewer under a National Pollutant Discharge Elimination System Phase II Municipal Separate Storm Sewer System permit, number GAG610000, and the City describes its own legal authority this way: "The COSS has adopted the Metropolitan North Georgia Water Planning District's (MNGWPD) Model Illicit Discharge and Illegal Connection Ordinance. This Ordinance prohibits non-stormwater discharges into the storm sewer system and establishes appropriate enforcement procedures" (City of Sandy Springs, Stormwater Management Program, 2024 filing, read 2026-09-02). "COSS" is the City's own abbreviation for itself. The City records that ordinance as sitting at Municode Division 9.8, with the adoption date last updated August 15, 2017.
The Metropolitan North Georgia Water Planning District wrote the model ordinance and does not enforce it. The District describes itself as collaborating "with 97 cities and 15 counties to conserve and protect our region's vital yet limited water resources", says it was "Established by the Georgia legislature in 2001 and staffed by the Atlanta Regional Commission (ARC)", and states that "Over 100 different jurisdictions fulfill the Resources Management Plan requirements which are enforced by the Georgia Environmental Protection Division" (Metropolitan North Georgia Water Planning District, About, read 2026-09-03). So the chain over a Sandy Springs parking lot runs from a federal rule, through a state permit administered by Georgia EPD, to a city ordinance the City itself enforces.
The federal definition underneath all of it is short. Title 40 of the Code of Federal Regulations, section 122.26(b)(2), defines an illicit discharge as "any discharge to a municipal separate storm sewer that is not composed entirely of storm water except discharges pursuant to a NPDES permit (other than the NPDES permit for discharges from the municipal separate storm sewer) and discharges resulting from fire fighting activities" (read 2026-08-31). Wash water carrying detergent, grease and parking lot sediment is not composed entirely of storm water. Thrare Contracting publishes no penalty figure on this page, because the commonly repeated dollar amounts do not trace to the statute.
The City of Sandy Springs sets itself the goal of investigating an illicit discharge complaint within three business days. The City states it plainly in its Stormwater Management Program: "Investigate illicit discharge complaints within three (3) business days" (City of Sandy Springs, 2024 filing, read 2026-09-02). Three business days is the number a property manager should plan around, because it is shorter than most vendors stay on site.
That timing is what turns a contractor's shortcut into an owner's problem. A crew that pushes dirty wash water into a lot inlet on a Thursday morning is off the property by Thursday afternoon. The complaint, whether it comes from a tenant, a neighboring owner or a passerby, reaches the City, and the City arrives while the stain is still on the pavement and the contractor's invoice is still unpaid. The person who answers the questions is the property manager, and the evidence that helps is a dated photo record showing where the water was recovered.
The rest of the City's own program explains why complaints are taken seriously rather than filed. The City reports that "There are currently 636 MS4 outfalls" in its system, and commits to "perform screening of MS4 outfalls within its current inventory at the rate of approximately 20% per year but at least 5% each year", rotating the work so that "100% of the inventoried MS4 outfalls are screened over a five-year period" (City of Sandy Springs, 2024 filing, read 2026-09-02). The City lists the Chattahoochee River Basin as the receiving water for its MS4, and records that "Fulton County currently fulfills the City's bacteria and analytical monitoring requirements for Long Island Creek, Marsh Creek, and Ball Mill Creek" under a Memorandum of Agreement. A commercial property that drains toward one of those three creeks sits inside a monitored catchment.
Containment on a Sandy Springs commercial site is chosen at the walk, from four methods: protect the inlet and release across a vegetated area away from the drainage path, berm the zone and vacuum recover into a holding tank, filter and mat before a controlled release, or haul recovered water off site. Thrare Contracting writes the chosen method into the quote. Containment carries a real cost, and a proposal that omits the method is not a cheaper proposal, only a less complete one.
A commercial exterior cleaning scope is priced surface by surface, because the surfaces on one property tolerate different pressure, carry different soil, and belong to different people.
A wash on an occupied commercial property is sequenced against the delivery schedule and the lease, which keeps every zone except the one being worked available to tenants and customers.
A Sandy Springs commercial quote is built from six inputs, and the quote names all six so a manager can compare it line for line against the next bid: measured area by surface type, access and reach, soil load, containment method, working hours, and visit frequency.
Thrare Contracting publishes no price per square foot on this page. A published rate cannot see the access, the soil load, the containment method or the hours, and a rate quoted without them is a number that gets revised after the walk, which helps nobody comparing bids.
Thrare Contracting schedules exterior cleaning in Sandy Springs inside the hours the City publishes for construction and commercial landscaping, and treats that window as company policy rather than as a rule written for this trade.
The City of Sandy Springs publishes the window on its Code Enforcement page: "Construction and commercial landscaping activities are permitted only during the following hours", Monday to Friday 7:30 a.m. to 7:30 p.m., Saturday 8 a.m. to 5 p.m., and for "Sundays and holidays: No permitted hours" (City of Sandy Springs, Code Enforcement Division, Common Violations, read 2026-09-02). The same page states that "Anyone seeking to work outside of these permitted hours must first obtain a variance from the Community Development Department", and adds the general standard that "Noise that is excessively loud or disturbing and that interferes with the comfort, peace, health, or safety of others may be considered a nuisance."
Two qualifications belong with those hours, and leaving them out would misrepresent the City. First, that page is the City's own summary of the most common residential code violation complaints it receives, and it cites no ordinance section number. Second, the page does not name pressure washing, power washing or exterior cleaning anywhere in it. So the honest reading is that the City has published a working window for noisy outdoor commercial activity, and that a contractor who stays inside it is unlikely to generate the complaint, not that the City has issued a pressure washing curfew.
That distinction matters commercially, because retail wants the opposite of what the window offers. A shopping center manager asking for a storefront walkway cleaned before a 10 a.m. opening can have it inside the published window with a 7:30 a.m. start. A manager asking for a 5 a.m. start before a grocery anchor opens is asking for work outside the window, and the answer is a variance conversation with Community Development plus the lease restrictions on the property, not a quiet start and a hope. Thrare Contracting reads both before quoting early or overnight work, and prices the hours as a separate line so the choice is visible.
A loading dock or restaurant service yard is a compliance surface for the tenant who operates it, which is why it is cleaned on the tenant's inspection cycle rather than on the building's cosmetic one.
Georgia Administrative Code Rule 511-6-1-.07, the physical facilities rule for food and lodging establishments, states at subsection (2)(q) that "Outdoor refuse areas shall be constructed in accordance with Law and shall be curbed and graded to drain to collect and dispose of liquid waste that results from the refuse and from cleaning the area and waste receptacles", and at subsection (2)(p) that "Exterior walking and driving surfaces shall be graded to drain" (Rules of the Georgia Department of Public Health, published by the Georgia Secretary of State, current through rules filed through August 14, 2026, read 2026-09-02). Subsection (5)(b)1 requires that "The physical facilities shall be cleaned as often as necessary to keep them clean and by methods that prevent contamination of food products."
That rule governs the food service establishment, not its cleaning contractor. Read correctly, it tells a Sandy Springs retail manager two useful things. A restaurant tenant carries a standing duty to keep the refuse area clean, so the cleaning frequency at that pad is set by the tenant's inspection exposure and belongs in the tenant's schedule. And a pad that drains across the parking lot instead of to a collection point is a construction defect that no wash frequency corrects; a contractor who notices it should write it down rather than quietly wash around it every quarter.
Practically, a dock and service yard scope on a Sandy Springs property runs as its own visit: hot water and degreaser on the pad and apron, the enclosure walls and gates washed, the bollards and the curb line cleared, the grease line at the door treated, and the water recovered rather than pushed toward the lot inlet that sits, on most sites, within 40 feet of the compactor.
Washing pavement strips the film off the markings and shows how worn the accessible spaces already were. Restriping is not part of a cleaning scope, so the useful output of a wash is a written report of what the clean pavement now shows, measured against the published federal minimums.
The 2010 ADA Standards for Accessible Design set those minimums, and the numbers are dimensional rather than aesthetic (United States Access Board, sections 208 and 502, read 2026-09-03):
Two of those findings cannot be fixed with paint, and a Perimeter Center deck is where both turn up. A van route with less than 98 inches of vertical clearance is a structural condition, and an access aisle sloping steeper than 1:48 is a grade condition. Striping over either one hides a defect rather than correcting it. Those are the federal minimums only: a local code, a state requirement or a franchise standard can require more, never fewer.
One claim worth retiring from vendor proposals is that a parking lot must be marked to the Manual on Uniform Traffic Control Devices. Under 23 CFR 655.603(a), the MUTCD is "the national standard for all traffic control devices installed on any street, highway, or bicycle trail open to public travel", and that definition reaches roads "within shopping centers, airports, sports arenas, and other similar business and/or recreation facilities that are privately owned". The same paragraph then states that "Parking areas, driving aisles within parking areas, and private highway-rail grade crossings are also not included in this definition" (read 2026-09-03). The roads through a Sandy Springs shopping center are inside the definition; the parking bays and their driving aisles are not.
Washing frequency follows exposure and soil load instead of a fixed annual date, and one commercial property normally runs several intervals in parallel.
Rainfall is the background load, and it is worth stating what is actually published for this area. The National Oceanic and Atmospheric Administration publishes no 1991-2020 annual precipitation normal for a Sandy Springs station. The nearest published normals bracket the city: Atlanta Hartsfield-Jackson International Airport, station USW00013874, at 50.43 inches, and Norcross, station USC00096407, at 56.32 inches (NOAA National Centers for Environmental Information, US Climate Normals 1991-2020, read 2026-09-02). Neither figure is a Sandy Springs measurement, and a normal is a 30 year station average rather than a total for any single year. Rainfall at that order leaves shaded walls wet long enough for algae to establish, and it carries lot sediment onto walkways all year.
Thrare Contracting sets an interval per surface, writes it into a recurring program, and uses the dated photo record from each visit to move a surface up or down an interval instead of guessing at renewal.
A property manager should collect a W-9 and a certificate of insurance before any exterior contractor mobilizes, and should know what each document does and does not do.
A certificate of insurance is evidence, not coverage. Georgia's Rules of the Commissioner of Insurance, Subject 120-2-103, require a certificate to carry this statement: "This certificate of insurance is issued as a matter of information only and confers no rights upon the certificate holder. This certificate does not amend, extend or alter the coverage, terms exclusions and conditions afforded by the policies referenced herein" (Georgia Administrative Code, rules 120-2-103-.01 through 120-2-103-.05, read 2026-09-03). The rules define a certificate holder as any person other than a policyholder who requests or possesses a certificate. A manager who wants a right rather than information asks for the endorsement, not for a prettier certificate. That is buyer guidance about any contractor's paperwork and says nothing about the policies behind any particular certificate.
The W-9 matters for a different reason. The Internal Revenue Service explains that Form W-9 is used "to provide your correct Taxpayer Identification Number (TIN) to the person who is required to file an information return with the IRS", and states that "There are situations when the payer is required to withhold at the current rate of 24 percent", including where a payee "failed to provide a correct taxpayer identification number (TIN) to the payer for reporting on the required information return" (IRS, About Form W-9, and IRS, Backup Withholding, both read 2026-09-03). Backup withholding is an obligation that lands on the payer, which is the property owner or management company, so a missing or mismatched W-9 is the manager's exposure and not only the vendor's.
Thrare Contracting completes a W-9 under the legal name Rare Earth Ltd instead of the trading name, issues a certificate of insurance on request carrying whatever certificate holder wording the management system specifies, and supplies safety data sheets for every chemical brought onto the property together with the registrations listed at the top of this page. General liability is the coverage line relevant to exterior cleaning work, and no coverage figures are published on this website.
Mobilizing once for several scopes costs a property less than mobilizing separately for each. Work that shares a visit with commercial exterior cleaning includes building washing, parking lot and garage cleaning, gutter cleaning, grounds maintenance and restaurant exterior cleaning. The full Sandy Springs list sits on the Sandy Springs pressure washing page, and the metro program sits on the commercial pressure washing page for Atlanta. Property managers running multiple assets can start from the property managers page.
Thrare Contracting is based in Atlanta and covers Sandy Springs as a service area. The company address is 8735 Dunwoody Pl, Ste R, Atlanta, GA 30350, the legal entity is Rare Earth Ltd, and the business was formed on January 19, 2020.
The City of Sandy Springs rule applies, not the Fulton County one. Fulton County states that its stormwater program manages "the surface water resources of unincorporated Fulton County" and that "For all other areas of the County, stormwater management is the responsibility of the individual cities". The City of Sandy Springs runs its storm sewer under NPDES Phase II MS4 permit GAG610000 and has adopted the Metropolitan North Georgia Water Planning District model illicit discharge ordinance, recorded by the City at Municode Division 9.8.
The City of Sandy Springs commits in its Stormwater Management Program to "Investigate illicit discharge complaints within three (3) business days". A wash crew is usually off the property well inside that window, so the property manager is the person who answers the questions, which is why a dated photo record of the containment method is worth having.
Thrare Contracting schedules Sandy Springs work inside the hours the City publishes for construction and commercial landscaping: Monday to Friday 7:30 a.m. to 7:30 p.m., Saturday 8 a.m. to 5 p.m., and no permitted hours on Sundays and holidays. The City's page is a summary of common code violation complaints, cites no section number and does not name pressure washing, so that window is company scheduling policy rather than a rule the City wrote for this trade. Work outside those hours needs a variance from the Community Development Department, and the City says so on the same page.
Pressure washing removes the film and makes the wear visible, and restriping is a separate trade that is never inside a cleaning price. The 2010 ADA Standards set the minimums a report is measured against: access aisles 60 inches wide minimum extending the full length of the space, van spaces 132 inches wide minimum, no change in level across an access aisle beyond a 1:48 slope, and 98 inches minimum vertical clearance on a van route. A low deck clearance or a steep aisle slope cannot be corrected with paint.
A management company should collect a W-9 and a certificate of insurance before mobilization. Georgia's certificate of insurance rules require the certificate to state that it "is issued as a matter of information only and confers no rights upon the certificate holder", so a manager who needs a right asks for the endorsement rather than the certificate. The IRS requires a payer to withhold at the current rate of 24 percent where a correct taxpayer identification number was not provided, which makes a missing W-9 the payer's exposure. Thrare Contracting completes a W-9 under the legal name Rare Earth Ltd and issues a certificate on request.
