Professional Window & Door Service in Pleasant Hill

Pleasant Hill's housing stock is a mix of mid-century homes, 1970s–80s builds, and some newer construction, each with its own window replacement considerations. We're experienced with all of them. Older homes often benefit most from a retrofit replacement, upgrading to dual-pane Low-E glass while keeping framing intact. We walk every homeowner through the options and recommend what actually makes sense for their home and budget.

Window & Door FAQ

Quick answers to what we hear most. See our full FAQ →

Four steps: (1) You request a free estimate, either in-home or remote. (2) We measure, spec the right product, and send you a written quote. (3) Once approved, we order your windows or doors. Lead times are typically 3–5 weeks depending on what you ordered. (4) Installation day: our in-house crew does the work, cleans up fully, and walks through the finished job with you before we leave.
Full replacement only. We don’t repair broken hardware, re-seal leaking frames, or do glass-only swaps. If you’re not sure whether you need repair or replacement, just call us and we’ll give you an honest answer, not a sales pitch.
You can replace as few or as many as you need. One window, a few rooms, or the whole house. We take on all of it. Many customers start with the worst ones and come back for the rest later.
Yes. We can provide the product specs, color samples, and written documentation most HOAs require for window or door replacement approval. Just let us know your HOA’s requirements upfront and we’ll prepare what’s needed.
Yes, removal and disposal of your old windows and doors is included in every job. We clean up the work area completely before we leave. No pile of old frames sitting in your yard.
Never. Every installation is done by Alex and Leon’s own in-house crew. No day laborers, no strangers at your door. This is how we maintain consistent quality and stand behind our 4-year installation warranty.
A few things worth knowing upfront: we don’t do repairs of any kind (no hardware fixes, re-sealing, or patching), glass-only replacement, screen repair or re-screening as a standalone job, interior door installation, or installation of windows and doors you’ve purchased elsewhere. We do full replacement only: windows and exterior doors, start to finish.
