Why Mason Remodeling Co Miami Is Olympia Heights’s Preferred General Contractor Company
We’ve worked enough lots between Bird Road and Coral Way to know what the county will flag before we even submit plans. Olympia Heights is unincorporated Miami-Dade, which means no city hall permits, but stricter county reviews on wind loads, setbacks, and drainage. Our team has walked through the exact county checklist hundreds of times, and that familiarity saves you weeks of back-and-forth. Isaac Pruett, who leads our general contracting division, reviews every site plan personally before it leaves our office.
Homeowners in Olympia Heights consistently tell us the same thing: they want to know exactly who is showing up and exactly what it costs. That’s why every crew member under the Threshold Standard is background-checked, identity-verified, uniformed, and introduced by name and photo before they arrive. You’ll see a photo ID badge at the door. No surprises, no strangers.
Our written price is never verbal. It’s in your hand before tools come off the truck. And our 365-Day Done Right Promise means if something isn’t right within a year of completion, we make it right at no cost to you. That’s not a promotion. It’s how we’ve operated since 2004 as part of the Threshold Group family of home-service companies.
Styles & brands we work with
Hire a General Contractor in Olympia Heights
Hire a General Contractor in Olympia Heights when the job involves structural changes, county permits, or coordination across multiple trades. A licensed GC pulls the permits, schedules the inspections, manages the subs, and carries the liability. On a typical Olympia Heights home addition, expect $45,000 to $130,000 depending on square footage, foundation work, and whether you’re tying into existing CBS walls. Garage conversions run $30,000 to $80,000, and impact window installation typically lands between $8,000 and $25,000 for a full home.
County Permits and Site Plans
Unincorporated land means Miami-Dade County’s Building Department reviews every structural plan. We file the drawings, handle the plan review comments, and coordinate plumbing and electrical permits so you don’t have to chase down the clerk’s office.
Septic and Well Setbacks
Many Olympia Heights lots still run on septic and wells, not municipal sewer. County code requires specific distances between any new structure and the existing drain field. We check the survey before quoting so your addition doesn’t end up six feet from where you wanted it.
General Contractor Services in Olympia Heights
General Contractor Services in Olympia Heights cover everything from a detached workshop to a whole-home remodel. For a paver patio installation, plan on $3,500 to $11,000 depending on the size and whether we’re adding a pergola or outdoor kitchen. Homeowners often ask us to restore original terrazzo floors hidden under carpet or tile during a remodel – a detail that can save thousands if the slab is sound and we grind carefully.
Outbuildings and Detached ADUs
Building a detached ADU in Olympia Heights means county setbacks, drainage swales, and possibly moving a septic line. We scope the site survey, grade the lot, and write the change order before the pour so the inspection sign-off goes through without corrections.
Open Lot Grading and Drainage
The area’s flat terrain and daily rainy-season storms make drainage the difference between a dry slab and a moisture failure. We cut swales, set fill, and schedule pours around the 3 p.m. thunderstorm window.

AfterCommon General Contractor Problems We See in Olympia Heights Homes
- Assuming a city permit covers the job. Olympia Heights is unincorporated, so Miami-Dade County’s HVHZ plan review applies. A contractor who files the wrong jurisdiction wastes three weeks before the first inspection.
- Quoting an addition without checking the septic survey. Many 1960s lots have the drain field exactly where the new bedroom wants to sit. We check the setback before quoting, not after demo starts.
- Open subfloor and roof tear-offs in the rainy season. The daily 3 p.m. thunderstorm from May to October will soak exposed framing overnight. We schedule tear-offs for morning and tarp before the storm hits.
- Hidden terrazzo under carpet. If you want to restore it, we demo carefully and grind the surface without cracking the slab. If you want to cover it, we prep it properly for tile or LVP.

FAQs About General Contractor in Olympia Heights
Yes, you need a Miami-Dade County permit for any detached structure in Olympia Heights. Because the area is unincorporated, there is no city hall to issue a minor accessory permit. Your contractor must file with the county’s Building Department, and the structure must meet HVHZ wind load requirements plus septic and well setbacks. We handle the entire filing process for you. Call (850) 780-8123 and we’ll tell you exactly what your workshop needs before you spend a dollar.
A change order is a written document that records the added scope and its cost before the work continues. In Olympia Heights, tree roots and buried fill from older construction are common, so we photograph the condition, write the cost of extra excavation or root barricades, and get your signature before we proceed. You never pay for something we didn’t put in writing first. That’s how our no-surprise pricing actually works on an open lot. Call (850) 780-8123 for a free site walk.
Restoring terrazzo usually saves money compared to laying new flooring, but it’s not free. We need to demo the carpet and pad carefully, grind and polish the surface, and patch any cracks. In Olympia Heights, many homes still have the original terrazzo from the 1950s and 60s, and it’s often in better shape than homeowners expect. The cost runs lower than new tile or wood, and the finished floor is durable and unique. We’ll inspect it during the estimate and give you a line-item price.
Because the daily thunderstorms hit fast and hard, usually between 2 and 5 p.m. Exposed subfloor or a torn-off roof that gets soaked overnight will fail the county’s moisture check and need to be dried out or replaced before inspection. We schedule tear-offs and open-slab work in the morning and tarp everything before the storm arrives. It’s one of the biggest scheduling factors on any Olympia Heights project. Call (850) 780-8123 to talk about timing for your project.
Inspection sign-off means the county inspector has physically verified each stage of the work – foundation, framing, mechanical, and final – and approved it in the county’s system. In Olympia Heights, this is Miami-Dade County, not a city inspector. Your lender typically releases final payment or the last draw only after the final sign-off is posted. We build our schedule so inspections happen in the right order, and we don’t ask for a draw until the county confirms the stage is passed. Call (850) 780-8123 and we’ll walk you through the draw schedule for your specific addition.
