Typical installed prices for every service we offer, what moves them, and a calculator for a ballpark. These are typical ranges from national cost guides. Your own price comes from the free inspection, as a fixed, written quote.
Installed prices for residential work, labor and materials included, where national cost guides published in 2025 and 2026 agree. Where a service has its own page, the link has the details.
| Service | Typical installed price | What moves it |
|---|---|---|
| Crawl space | ||
| Crawl space encapsulation | $5,000–$15,000 | About $3–$7 per square foot of crawl space floor. Liner thickness, wall coverage, sealed vents and doors, a dehumidifier and repairs underneath set where you land. |
| Vapor barrier only | $1,500–$3,000 | $2–$4 per square foot for a ground liner. Thicker reinforced liner and running it up the walls cost more. |
| Crawl space dehumidifier | $1,000–$2,000 | A crawl-space-rated, self-draining unit, installed. Larger and ducted units sit at the top of the range. |
| Mold removal in a crawl space | $500–$2,000 | Treating the framing and cleanup. Fixing the moisture that fed it is priced on its own. |
| Crawl space cleaning | $500–$2,500 | Hauling out old insulation, torn plastic and debris. More when wet insulation or mold is involved. |
| Insulation replacement | $1,000–$3,500 | $1–$4.50 per square foot installed, including removal of the old insulation. Spray foam and rigid board cost more than batts. |
| Crawl space waterproofing | $2,000–$7,000 | Most jobs. A full perimeter drain, sump pump and sealed liner on a large crawl space can reach $15,000. |
| Interior French drain | $40–$100 / linear ft | A 100-foot run is about $4,000 to $10,000 before the sump pump. |
| Sump pump with basin | $800–$2,000 | Installed. A long discharge line, battery backup or an alarm add to it. |
| Water under the house | $2,000–$10,000 | Pumping out, drying, and repairing wet insulation and wood. The longer it sat, the higher it goes. |
| Floors and framing | ||
| Sagging floor repair | $1,000–$5,000 | Supports under a dropped beam at the low end; replacing rotted joists or a beam at the high end. |
| Floor joist sistering | $100–$300 / joist | Replacing all the joists under one room runs about $5,000 to $10,000. |
| Main beam (girder) replacement | $1,500–$5,000 / beam | Wood or steel, depending on the span and access. |
| Structural repair in a crawl space | $1,000–$7,500 | Most jobs combining joist, sill and support work. |
| Wood rot repair | $750–$5,000 | How far the rot runs through sills, joists and subfloor sets the price. |
| Termite damage repair | $600–$3,000 | Localized wood repair. Treating the termites is a separate job for a pest control company. |
| Basements | ||
| Basement waterproofing | $3,000–$8,000 | Most basements, usually an interior drain and sump. Digging out and sealing the outside of the walls runs $10,000 to $15,000. |
| Basement leak repair | $2,000–$7,000 | Leaks that need drainage and a pump. A single leaking crack costs far less. |
| Wall crack injection | $250–$800 / crack | Polyurethane or epoxy injected from inside. Length and material set the price. |
| Bowed wall repair | $4,000–$12,000 | Carbon fiber straps, steel braces or wall anchors on a typical wall. Walls that need straightening or rebuilding cost more. |
| Basement French drain | $40–$100 / linear ft | Most basements need 100 to 150 feet, plus the sump pump. |
| Foundations | ||
| Foundation repair (most jobs) | $2,200–$8,200 | National average about $5,200. Crack sealing is a few hundred dollars; piering costs more. |
| Push or helical piers | $1,000–$3,000 / pier | Most settlement repairs need several. Larger piering jobs run about $10,000 to $30,000; helical piers often sit at the top of the per-pier range. |
| Foundation waterproofing | $2,500–$7,000 | Sealing and waterproofing a foundation. Full excavation with a membrane and footing drain costs more. |
| Pier and beam repair | $2,000–$15,000 | Re-shimming and leveling at the low end; new piers and a main beam at the high end. |
Typical ranges as of October 2026, from the HomeAdvisor, This Old House, Fixr, HomeGuide and Today's Homeowner cost guides. They are published typical ranges; Trench Guys prices every job in writing after a free inspection. Labor is a big share of these jobs, and construction wages in the Macon area run below the national average, but what is under your house moves the price more than anything else.

Two homes on the same street can need very different work. These are the lines that make the difference on a quote.
Square footage drives liner, drain and insulation jobs. A crawl space under two feet tall slows every step, and some jobs need hand digging or extra hands.
Wet insulation, debris, mold or rotted wood has to come out or be repaired before anything new goes in, and that prep is its own line on the quote.
A crawl space that floods after rain needs a drain and sump pump before it can be sealed. One that is only humid may need a liner and a dehumidifier.
A thin floor sheet, a heavy reinforced liner run up the walls, sealed vents and doors, and a dehumidifier are four different price points.
Sistering a few joists costs a few hundred dollars each; a new main beam or a row of piers costs thousands. The number of piers and the depth to firm soil set a foundation price.
Exterior drains, waterproofing and piers mean excavation, a Georgia 811 locate request first, and sometimes a building permit.
