Home Weatherization in Lexington, SC

Drive through Lexington’s newer neighborhoods off Sunset Boulevard or out toward Red Bank and you’ll see the same story house after house: two-story vinyl-sided homes built between 1995 and 2015, sold with builder-grade insulation that barely met code the day it went in. Fifteen or twenty Lake Murray summers later, that thin attic blanket and the unsealed gaps behind it are why upstairs bedrooms won’t cool down and July power bills clear $400.

Home weatherization fixes the house itself — sealing the leaks, restoring the insulation, and tightening the ductwork — so the AC you already own finally keeps up. Attic and Crawl Space Solutions has weatherized Midlands homes since 2014, and every Lexington project starts with a 100% free inspection and a written quote.

What Home Weatherization Covers in Lexington

“Weatherization” is the umbrella for every upgrade that makes a Lexington home hold its conditioned air instead of leaking it. A project can be one of these or all of them together — the free inspection tells you which ones your house actually needs:

• Attic insulation — blown-in or batts to R-38–R-49, the backbone of every weatherization project
• Air sealing — closing the gaps, chases, and penetrations that let conditioned air escape
• Duct sealing — mastic-sealed, insulated ductwork so cool air actually reaches the rooms
• Blower door testing — before-and-after numbers that prove the improvement
• Home energy audits — a whole-house diagnosis when you want the full picture
• Crawl space moisture control in Lexington — sealed vapor barriers and dehumidification, because humidity is half of a South Carolina energy bill

Built Fast, Insulated to Minimum: Lexington’s Housing Stock

Lexington grew faster than almost anywhere in the Midlands over the last twenty-five years, and speed shows up in the details: R-19 attics where R-38 to R-49 belongs, duct trunks run through 130-degree attics, bonus rooms over garages with almost nothing in the knee walls, and top plates that were never air sealed. None of it is visible from the living room — all of it shows up on your bill.

The fix is straightforward and permanent. We air seal the attic plane first (it’s the step production builders skipped), then blow insulation to R-38–R-49, seal and insulate the ductwork, and verify the whole envelope with a blower door test so you can see the improvement as a number, not a promise.

Why Lexington Homes Bleed Energy in a South Carolina Summer

A Lexington two-story fights a specific battle: heat soaks the roof deck all afternoon, radiates into an under-insulated attic, and pours down into second-floor bedrooms just as the family gets home. Meanwhile conditioned air leaks out of attic ducts before it ever reaches a register. The symptoms are predictable:

• Upstairs runs 5–8 degrees hotter than the thermostat floor
• Bonus room over the garage is unusable by 4 PM
• AC runs continuously from June to September
• Power bills that jumped a size class since you bought the house

Every one of those symptoms has a measurable cause, and weatherization fixes causes — not symptoms. That’s why the results hold up year after year with zero maintenance.

How a Weatherization Project Works

• Free inspection — we measure insulation depth, check ducts, inspect the crawl space, and photograph everything.
• Written quote — exact scope and exact price, explained in plain English. No pressure, no expiring discounts.
• One- to two-day install — air sealing first, then insulation, then ducts. Clean crews, protected floors.
• Verification — blower door numbers and photos of the finished work, so you can see what you paid for.
