Home Additions, ADUs, Basement Finishing & General Contracting in Westminster, CO
D&J's Construction Services runs out of Arvada, about four miles from Westminster. That's not a selling point about convenience; it's a fact about how quickly Joseph can be on your property, look at the actual conditions, and give you a number that reflects what the job really is. He's been in construction for over fifteen years and has done every part of the work himself: drawn the architectural plans, handled the structural engineering, filed for permits, and swung the hammer. Most contractors hand those pieces off to whoever is available. Joseph keeps them together because the problems always live at the handoffs between them.
Westminster homeowners tend to have solid lots and houses with real square footage potential, and the calls Joseph gets most often are from people who want more space without moving. A finished basement turns unused square footage into something the family actually uses. A home addition pushes a wall out and gives you the room you've been rearranging furniture to fake. An ADU gives a separate unit to a family member or generates rental income from ground you already own. Whatever the project, Joseph is the one who picks up when you call (303) 570-2753, and he's the one you'll talk to at every step after that.

One contractor who handles the whole job
The way most residential construction works is fragmented by design. A designer draws plans without talking to the engineer. The engineer stamps them without knowing what the builder will actually find in the walls. The builder asks questions nobody answered on paper, and the homeowner ends up in the middle of three phone calls that should have been one conversation months earlier. Joseph built D&J's to eliminate that structure entirely. He prepares the architectural drawings himself. He does the structural engineering himself. He pulls the permit himself. Then he runs the build. That means when something changes, and something always changes once walls open up, the person who can make the call is already on site, not somewhere waiting to be contacted. It also means the drawings that go to the permit counter actually match the way the work will be done, because the same person who drew them is the one building from them. Because Joseph handles every phase in sequence rather than handing off between offices, he catches conflicts between the design and the structural requirements before they become field problems. That coordination happens internally, during the drawing and engineering phase, so by the time a permit is filed the plans reflect how the job will actually be built. Westminster is close enough to the Arvada shop that Joseph can be on your lot fast, look at your specific conditions, and give you a plan that fits your house rather than a template. Estimates are free, and he carries full licensing and insurance with proof available before any work begins.

General Contracting
From a kitchen gut to a full structural remodel, Joseph manages the project the same way across every job: he knows what's been drawn, what's been engineered, and what the crew is doing each day. You're not tracking down subcontractors or wondering whether the plans match reality. One person holds all of it. - 02
Home Additions
Adding square footage to a house is an engineering problem before it's a carpentry problem. The new structure has to tie into the existing one correctly, and the loads have to be calculated before a wall comes down. Joseph handles both sides, the design and the structural math, then builds it. - 03
Basement Finishing
An unfinished basement is usable square footage you're already paying for. Framing, insulation, mechanical coordination, drywall, trim, and flooring. Joseph runs it as a single organized sequence rather than a series of separate bids. The result is a space that feels like the rest of the house, not an afterthought. - 04
ADU Construction
Backyard cottages, garage conversions, granny flats. ADU work requires drawings, engineering, and permitting before a shovel moves. Joseph does all three in-house, which cuts out the delays that come from plans sitting between offices that have never spoken. Westminster lots can be good candidates for this kind of project.

Why the owner-run model changes how the work goes
A lot of contractors are project managers who coordinate people they've hired. That structure works until something goes sideways: a framing condition that doesn't match the drawings, a structural detail that needs a field decision, a material that's backordered and requires a substitution someone has to approve. In those moments, the question is always who actually has the authority to make the call and how long it takes to reach them. Joseph is the architect, the structural engineer, and the builder. When a question comes up on a Westminster job, the answer doesn't have to travel anywhere. He's standing there. That matters most on additions and ADUs, where the design, the engineering, and the construction have to stay tightly coordinated through every phase. It matters on basements too, where mechanical systems and existing structural conditions have a way of complicating what looked simple on paper. Because Joseph drew the plans, ran the engineering, and is now running the crew, he can read a field condition and know immediately whether it changes the structural assumptions or just the sequencing. He doesn't have to call a designer or wait for an engineer to review a photo. He makes the call, adjusts the work, and keeps the job moving. Over fifteen years of doing this kind of work, Joseph has learned that the jobs that go smoothly are the ones where the person making decisions actually understands the whole project from foundation to roof. D&J's is built around that idea, and it shows in how the work runs day to day.
From first call to finished work.
Every D&J's project in Westminster follows the same sequence. No handoffs between offices, no gaps between phases.
1. You call, Joseph answers
When you dial (303) 570-2753, you reach the owner. Not a scheduler or a sales rep. Joseph asks the real questions about your project on that first call: what you're trying to build, what the existing conditions look like, and what your timeline is. That way he shows up to the site visit already thinking about your specific situation rather than starting from scratch when he walks in the door.
2. Site visit and free estimate
Joseph comes to your Westminster property, walks the space, and looks at the actual conditions. He measures, checks the structure, and asks anything the phone call left open. The estimate that follows is based on what he saw, not a formula applied from a distance. Because he's done the design and engineering work on jobs like yours before, he knows during the site visit which conditions will drive cost and which ones are straightforward.
3. Architectural drawings
Joseph prepares the drawings himself. They reflect the real dimensions and conditions of your house, not a generic plan adapted after the fact. Because he's also the one building from them, they're drawn the way a builder thinks, not just the way a designer prefers. Details that matter in the field, like how a new beam bears on an existing wall or how a floor system transitions at an addition joint, are worked out on paper before anything is ordered or framed.
4. Structural engineering and permit
Joseph handles the structural calculations and prepares what the permit counter needs. He files it. Pulling your own permit as the contractor of record means he's accountable for the work meeting code, and he knows exactly what was submitted and what the inspectors will be looking for. There's no lag between the engineering and the permit application because the same person is doing both.
5. The build
Joseph runs the crew. He's on site, not managing the job from an office. When conditions in the walls or the foundation differ from what the drawings assumed, the person who drew the plans and did the engineering is right there to adapt without a delay. He can look at what the walls reveal, compare it to what he designed, and make a sound decision on the spot rather than waiting for outside review.
6. Walkthrough and close
When the work is done, Joseph walks the finished project with you. Any punch-list items get handled before the job closes. You have his number and he's four miles away. If something comes up after, you're calling the person who built it.

Westminster projects, handled close to home
Four miles is a short drive, and it shows up in how jobs here actually run. Joseph can make a quick site visit to check a condition, drop off materials, or deal with something that came up without it becoming a half-day commitment. That proximity keeps Westminster jobs moving. It also means when you call with a question mid-project, he can often just come look rather than trying to diagnose the situation over the phone. When he does come out mid-project, he's not just eyeballing the work; he's checking it against the drawings and the engineering he produced, so he can tell immediately whether what he's seeing is within the plan or needs an adjustment. That's a different kind of site visit than one where a project manager is relaying observations back to a designer somewhere else. D&J's is licensed and insured, and Joseph can show you proof of both before any work starts. That's not a formality. It's the basic standard a homeowner should hold any contractor to, and it should be easy to verify before you sign anything. If you have a project in mind and you want to talk through what it actually involves, call Joseph directly. He'll tell you straight what the job looks like, what it will take, and what a realistic number is. The estimate costs you nothing.
