What Dallas Homeowners Say About Woolsey Insulation Dallas
Reviews aren’t decoration on a website. They’re a record of whether a company did what it said it would do, on the day it said it would do it, for the price it put in writing. We ask every Dallas customer to tell us straight how the job went, because the only way we keep the 365-Day Done Right Promise honest is by hearing about the times something didn’t go right. Glenn Hartley, our owner, reads every single review himself. The six below are from real insulation jobs in Dallas over the past year. They reflect the way we work: a written price before anything starts, techs in uniform who show up on time, and a guarantee in writing on every job.
Recent Reviews
“I’d been putting off attic insulation for years because I didn’t want to deal with pushy salespeople. Woolsey sent a tech who walked the attic, showed me photos of the bare spots, and handed me a written quote before he left. No pressure. They blew in Owens Corning fiberglass the following week and the upstairs stopped baking by 4 p.m. every afternoon.”
Ruben R. – Lakewood, Dallas
“Our electric bills in July and August had been running over $400 for a 1,900 square foot house. The tech found gaps around the attic hatch and recessed lights, plus old insulation that had settled to about four inches. They air-sealed everything and brought it up to R-38. First full summer after that, our highest bill was $260. I wish we’d done it years ago.”
Javier R. – North Oak Cliff, Dallas
“I called on a Sunday afternoon expecting a voicemail. A real person answered, scheduled us for Tuesday, and the tech texted when he was 20 minutes out. The spray foam job in our garage ceiling was clean, the workspace was spotless when he left, and the written guarantee was attached to the invoice. That’s how it should work.”
Marcy N. – Casa View, Dallas
“The previous owner of our house had done some questionable DIY work in the attic, including blocking the soffit vents. Woolsey removed the old crap, corrected the venting, and installed Johns Manville batts. Two weeks later we got hit with that June heat wave and our AC finally could keep up. The upstairs bedrooms stayed at 72 instead of 82. I checked the work myself afterward and it was tidy, which matters to me.”
Ernesto R. – Pleasant Grove, Dallas
“We wanted spray foam in a 1950s ranch attic with a low slope roof. Two other companies told us different things. The Woolsey tech explained open-cell versus closed-cell in plain English, recommended open-cell for our situation, and gave us a detailed written scope. The crew showed up in matching uniforms, laid drop cloths down the hallway, and finished in a day. It’s hard to find contractors who treat your house like that.”
Ruben R. – White Rock Valley, Dallas
“I got three quotes for attic insulation. Woolsey wasn’t the cheapest and wasn’t the most expensive, but they were the only ones who put the price in writing before I had to ask. They used GreenFiber blown-in cellulose, which I’d researched and specifically wanted for the sound dampening between our two-story house and the busy street. The install crew was polite, background-checked, and the attic looked better after they left than before they arrived. The 365-day guarantee in writing sealed it for me.”
Marcy N. – Lake Highlands, Dallas
Why Customers Trust Us
Every review above mentions something we don’t leave to chance. The written price before work starts shows up in almost every single one, because that’s the moment people feel safe moving forward. The clean job site gets mentioned too, and so does the guarantee. Those aren’t coincidences. They’re the way we’ve operated since 2002, and they’re written into how every job runs. When Ruben mentions a tech showing him photos of bare spots, that’s our techs doing what they’re trained to do: show evidence, explain the fix, and let you decide. When Javier saw his bill drop from over $400 to $260, that’s what proper air sealing and R-38 attic insulation actually does in a Dallas summer. When Marcy called on a Sunday afternoon, she reached a live person because that’s the only way we’ve ever answered the phone. No voicemail, no callback window. That’s part of being independently owned and operated under the Kingswell banner. Glenn Hartley runs this location personally, and the 365-Day Done Right Promise is his name on the line. If something isn’t right within a year, we come back and fix it at no charge. It’s in writing on every job. Call (469) 916-4622 and let us take a look at your attic. You’ll get a written price before anything starts, and a real person answers the phone any hour you call.
