Remodeling Company in West Covina, CA
Remodeling in West Covina is its own animal, and if you live here, you already know why. The city’s hillside lots, mid-century tract homes, and shifting clay soils create conditions flatland suburbs never deal with. We’re Mason Remodeling, part of the Threshold Group family of home-service companies since 2004, and we handle general contracting, bathroom remodels, and whole-home remodels across West Covina. Every crew member is identity-verified and introduced by name and photo before arriving at your door. Call us at (707) 760-7579 for a free estimate and a written price before any work starts.
Why West Covina Homes Are Different

Most West Covina homes were built between 1950 and 1980, and the housing stock tells that story in its bones. You’ll find ranch-style and two-story stucco houses with original wood framing, post-tensioned slab foundations, and electrical panels that were installed long before modern code requirements. Remodeling these homes means working around what’s already there, not starting from a blank slate.
The bigger variable is the terrain. West Covina spans both sides of I-10, and the difference matters. On the hillside streets above the freeway, we regularly encounter expansive clay soils that shift with the seasons. That means deeper footings, foundation retrofits, and retaining wall work that homeowners in flatter parts of the city rarely have to think about. South of the freeway, the ground is more forgiving, but the homes there share the same era of construction and the same need for careful planning.
The local climate adds another layer. Hot, dry summers and occasional Santa Ana winds push homeowners toward fire-resistant materials and drought-tolerant landscaping. Those choices ripple into hardscape, exterior, and even window decisions. None of this is exotic to a contractor who works here regularly, but it changes what gets specified and how the work gets sequenced.
Styles & brands we work with







Our Main West Covina Services
Most West Covina homeowners reach out to us for one of three things: a general contractor to manage larger projects, a bathroom remodel, or a whole-home remodel. Each has its own page below with pricing and details.
General Contractor in West Covina
General contracting in West Covina often means coordinating multiple trades across homes with hillside grading requirements and older structural systems. Whether it’s a kitchen overhaul, a structural repair, or a project involving additions, the work starts with a clear scope and a written price. On hillside lots, we account for soil movement and retaining-wall codes from the first walkthrough, not after excavation starts. Read more on our General Contractor in West Covina page.

Bathroom Remodeling in West Covina
Bathrooms in 1950s-to-1980s West Covina homes tend to be compact, and the plumbing is often original. Remodeling means working within post-tensioned slabs, which changes where drain lines can move and how quickly the job goes. We walk each homeowner through the options, from walk-in showers to tub-to-shower conversions, with pricing documented before work begins. Visit our Bathroom Remodeling in West Covina page for full details.

Home Remodeling in West Covina
Whole-home remodels in West Covina come in many forms, from updating interiors on a ranch-style home to reworking a two-story stucco house to fit a growing family. Older electrical panels, original framing, and hillside conditions all shape the plan. We deliver a written price before any tool is unpacked, and every project is covered by a written guarantee. See our Home Remodeling in West Covina page for scope and pricing.
