Temprano Construction is a licensed, EPA Lead-Safe Certified New Jersey general contractor serving Westfield homeowners with home additions, remodels, roofing, and siding — led hands-on by owner Ray Temprano from first call through final walkthrough.
Westfield is one of Union County’s most established communities — Victorian-era streetscapes, top-ranked schools, and a NJ Transit stop that connects you to New York in under an hour. Homeowners here don’t leave. They invest.
That investment mentality shows up in how Westfield homeowners approach renovations. When you’re sitting on a home that may have been in the family for decades — on a street where your neighbors have already done the additions — you want a general contractor who understands what this house is, what it’s worth, and what it takes to build on it correctly.
That’s what Temprano brings to Westfield.
Ray Temprano is a second-generation builder with 40+ years of combined family experience in Northern New Jersey construction. He is on-site, personally, at every project he takes — not a project manager you’ve never met. And as an EPA Lead-Safe Certified firm with Ray individually certified as a Lead Renovator, Temprano is built for the reality of Westfield’s housing stock: older homes, layers of history, and materials that require care.
Westfield’s homes span Victorian, Colonial Revival, and Craftsman bungalow styles — many of them built before 1950, some before 1920. The bones are solid. The footprints are often smaller than what today’s families need.
Adding a first-floor rear addition or a second story to a Westfield Colonial or Victorian requires GC experience that matches the architecture. These aren’t spec homes. Proportions matter. We plan additions that integrate with your existing rooflines, siding profiles, and interior flow — not additions that read like an afterthought from the street.
Pre-war and mid-century Westfield kitchens and bathrooms were designed for a different era. Opening sightlines, expanding layout footprints, and updating mechanicals — all coordinated under a licensed GC who pulls permits and does the work right.
From a dated 1960s hall bath to a full primary suite renovation — tile, fixtures, layout, lighting, and plumbing coordination handled under one roof.
From the ground up, we bring your new home vision to life — built right, on time, and on budget.
Westfield’s tree canopy is beautiful and hard on roofs. We handle inspections, tear-offs, and full replacements, plus siding that holds up to New Jersey weather without sacrificing the curb appeal your block expects.
Westfield basements are some of the more common projects we handle in Union County. Older foundations, proper egress planning, and correct moisture management are all part of what separates a lasting basement from one that needs redoing in five years.
The Westfield real estate market makes moving expensive. Buying up in this town — or in the surrounding Union County communities that carry the same school district value — means competing for limited inventory at prices that often don’t reflect what you’ll actually get.
An addition gives you the square footage your family needs in the neighborhood you already chose. A finished basement gives you the home office, gym, or flex space that a 1940s floor plan never included. A gut-reno kitchen gives you the space to actually cook in a house that was designed around a cast-iron stove.
We’ve seen Westfield homeowners time and again realize that the cost of a well-executed addition — $200–$400 per square foot for an addition, more or less depending on scope and materials — is a fraction of what it would cost to buy equivalent space in this market.
We’ve completed basement finishing work in Westfield — older Union County homes where the existing foundation, utility layout, and egress requirements all had to be addressed before we could build anything worth living in. That’s the kind of work that looks simple from the outside and requires experienced judgment to execute without problems later.
The process is the same regardless of project type:
If your Westfield home was built before 1978 — and most were — it may contain lead-based paint in walls, trim, windows, and doors. This isn’t a reason to panic, but it is a reason to hire right.
Temprano Construction is an EPA Lead-Safe Certified Firm (Cert #NAT-F321755-1), and Ray is individually certified as an EPA Lead Renovator (Cert #R-I-99273-26-01798). That means every renovation we handle in an older Westfield home follows EPA-required lead-safe protocols — protecting your family, our crew, and your property.
This certification is uncommon among Northern NJ general contractors. If you’re getting estimates for work on a pre-1978 home, it’s worth asking about it.
Projects Completed
From our base in Northern New Jersey, we regularly work in:
Westfield · Cranford · Scotch Plains · Fanwood · Mountainside · Summit · Springfield · Clark
We also serve homeowners across Essex, Bergen, Morris, Passaic, and Somerset counties. If you’re within an hour of Belleville, we can come to you.
Yes. In Westfield Borough, home additions and significant renovations require permits through the municipal construction office. Temprano pulls all required permits as part of every project scope — this is included in our process, not an afterthought. Permit timelines vary; they’re outside our control, but we plan around them.
If your home was built before 1978, the answer is probably yes — at least in some areas. Westfield’s housing stock skews significantly older than 1978. Temprano is EPA Lead-Safe Certified, which means we follow federally required protocols for any renovation work that disturbs these surfaces. This protects your family and is required by law.
Ask for their NJ Home Improvement Contractor license number and verify it at the NJDCA website. Temprano’s license is #13VH11462700 — active and verifiable.
Most additions we build run $200–$400 per square foot depending on scope, materials, and addition type. A 500 sq ft rear addition might run $100,000–$200,000; a full second-story add-a-level on a larger footprint will cost more. Every Temprano proposal is itemized — no vague ranges after you’ve signed.
Both. If you already have an architect and plans, we can work directly from your drawings. If you don’t, we can connect you with architects we work with in the area.
Yes. Ray Temprano is on-site at every project he takes. He’s not selling jobs and handing off to a crew. If you have a question mid-project, you call Ray.
Whether it's improving your home or upgrading your business space, we make every project simple, stress-free, and built to last.
