Topside Attic Insulation in Washington
Topside Attic Insulation delivers sealed-first attic insulation to homeowners across Washington, and has since 2016. We air seal before we insulate, every time, then document the result with before-and-after blower-door numbers so you can see the performance change in a single figure. As part of the Haven family, Topside works to the Haven Standard: a written price before any work starts, a named technician on a real schedule, verified crews, evidence on every job, and no doorway upsell. Washington homeowners get the same flat-price promise, the same documentation, and the same 365-Day Done Right Promise whether the attic is in a 1920s craftsman or a 2019 production build.
Why Washington Homeowners Choose Topside Attic Insulation
The order of operations matters more than most people realize. Blowing insulation over an unsealed attic floor is like putting a thicker coat over a leaky roof. Topside seals first: top plates, can lights, wiring penetrations, plumbing chases, any gap where conditioned air escapes. Only then does insulation go in. Materials come from Owens Corning, Johns Manville, Knauf, Rockwool, CertainTeed, Icynene, Demilec, and GreenFiber, which means product selection follows the house, not a supply contract. After every applicable job we publish the blower-door numbers, a pressurization measurement showing exactly how much conditioned air the home was losing before and how much after. Since 2016, the Topside crew has sealed and insulated more than 9,000 homes across Washington, and every one of them left with a written price agreed before work started and a documented photo record when the crew finished. Haven Standard Clause 1: flat price, written scope, written warranty before anyone lifts a tool. Clause 5: no upsell at the door. We also offer a free second opinion on any written estimate, where we read a competing quote with you line by line. No proprietary product lock-in, no mystery pricing, no “while we’re in here.”
Backed by the Haven Family
Haven has existed since 1998, and the model is deliberately simple: the local business stays local, and Haven supplies the standard that protects the customer. Topside Attic Insulation is independently owned and operated, with its own crews, its own license, and its own neighbors. What Haven contributes is the five published clauses every Haven company signs, the documentation system that proves the work, and the buying power that keeps pricing honest. A haven is somewhere nothing bad is going to happen to you, and that applies to every attic job Topside performs in Washington.
