What We Fix in Boulder County

• Professional Installation: Our certified installers follow manufacturer-specified procedures on every job, which keeps your warranty valid and your door performing as designed. Professional install avoids the costly problems that come from DIY or handyman attempts.
• Precise Measurements: We use laser-level tools and careful measurement to confirm every opening is sized and squared before install begins. That precision removes the gaps, binding, and uneven operation that plague badly measured jobs.
• Code Compliance: Every installation meets or beats local building codes for structural integrity, energy efficiency, and impact resistance where required. We handle permit applications and coordinate inspections so your project passes clean.
• Premium Brand Partnerships: As authorized installers for Andersen, Pella, and other top manufacturers, we offer access to the industry's finest door systems at competitive prices. Our brand partnerships also mean dedicated support and full manufacturer warranty protection for your investment.
• Waterproofing Expertise: Proper flashing and sealing around a sliding door opening is critical to preventing water damage. Our installers use proven waterproofing techniques and premium sealants to create a watertight barrier that protects your home's structure.
• Clean, Efficient Workmanship: We respect your home by protecting floors and furniture during installation, keeping the work area organized, and performing a thorough cleanup when the job is complete. Most installations are finished in a single day with minimal disruption.

Our Door Installation Process in Boulder County

1. Measure Opening. We measure the rough opening and check it against the door's specs, noting header height, sill level, and jamb plumb. Getting these numbers right up front is what makes the door fit clean later.
2. Check Level & Squareness. We use laser levels and squares to confirm the opening is level and plumb, and we correct the framing first if it is not. A door set in a crooked opening binds and leaks no matter how good the unit is.
3. Remove Old Door & Prepare Opening. We take out the old door and hardware, then prep the opening with flashing tape, waterproofing membrane, and a level sill pan. That gives the new door a weathertight base to sit on.
4. Install Tracks & Secure New Door. We set and level the track, hang the panels, adjust the rollers for smooth travel, fit the locks and handles, then seal, test, and inspect the whole assembly before we call it done.
