Backed by 7 years of building across Collin County and a full team of skilled trades, EXL Extreme Line Construction transforms kitchens and bathrooms, builds custom homes from the ground up, and creates additions and outdoor spaces that add lasting value to your home. From Princeton and McKinney to Allen and Plano, every project is managed start to finish, delivered on time and on budget, and built to a standard that holds up against North Texas weather and soil.
We’re a full-service general contractor based in Princeton, TX. For 7 years, we’ve helped homeowners across Collin County and North Texas remodel the homes they have and build the ones they want, from McKinney, Allen, and Plano to the fast-growing communities of Anna, Celina, and Melissa.
From kitchen, bathroom, and whole-home remodeling to ground-up custom homes, additions, ADUs, and outdoor living, our work covers the full range of residential construction. Every project is built to last, from the waterproofing behind your tile to the reinforced and post-tension slab foundations and drainage that stand up to the Blackland Prairie clay beneath Collin County homes.
Every project is led by one team and a single project manager, from the first estimate to the final walkthrough. Our trades are certified, we’re insured and bonded, and we stand behind every job with a workmanship warranty.
As your general contractor, we manage the entire project, with one team accountable for the whole build. From the first design sketch to the final city inspection, everything lives under one roof:
From the slab to the final coat of paint, every phase is planned and built to the same standard.
We build and remodel every part of the home, from foundations to finishes.
Most of Collin County sits on Blackland Prairie clay, a dense soil that swells when it rains and shrinks in summer heat. That seasonal movement is the leading cause of foundation problems in the area, which is why the foundation is where a sound build starts.
For new homes and additions, we plan the foundation around that soil from the beginning. On flat lots, that usually means a post-tension slab, where steel tendons are tensioned after the pour to keep the slab in compression and ride out the soil’s movement. We give the same attention to drainage and grading, since water pooling against a slab is what sets the cycle in motion. That groundwork is what keeps everything built above it sound for decades.
We won’t always be the lowest bid, and on a remodel or a new build, that usually works in your favor.
Your price comes down to three things: the size of the project, the materials you choose, and the quality of the work you can’t see once the walls and slab are closed up.
The lowest bid usually gets there by leaving something out, whether that’s a skipped permit, builder-grade materials, or rushed work behind the walls like waterproofing and framing. Those shortcuts rarely show on move-in day. They show up later, in repairs that cost more than the savings ever did.
We price the whole job up front, put every change in writing so there are no surprises on the invoice, and use materials built to last. Over the life of the work, that costs you less, not more. And when budget is a concern, we offer financing through a lending partner, so quality work stays within reach.
45+ completed builds and remodels across Collin County and North Texas, with a 5-star client rating.
A clear estimate up front, every change in writing, and no surprises on the invoice.
Licensed trades, full insurance and bonding, and a workmanship warranty on every job.
Spread the cost of a larger project over time through our lending partner.
We come out, walk your space, and give you a clear, written price. No pressure.
We lock in the plan, help you choose materials, and pull the permits your city requires, whether that’s Princeton, McKinney, Allen, or Plano. Permits add a little time, but they keep the work to code and protect you.
Your project manager runs the schedule and brings each trade in at the right time, sequencing foundation, framing, mechanicals, and finishes in order. You always know what’s next, and any change goes in writing and gets priced before we start it.
We handle the city inspections, walk the finished project with you, complete the punch list, and back it all with our workmanship warranty. One point of contact the whole way through.
EXL Extreme Line Construction is led by founder RJ Jenblat, who has spent the past 7 years building it into a construction company that homeowners and businesses across North Texas trust. He stays hands-on and involved in the details of every project, holding the work to one standard: real craftsmanship, honest communication, and practical solutions that bring a client’s vision to life.
Behind RJ is a team of more than 20, including certified trades who’ve done this work for years. When you hire EXL, you know who’s accountable for your home.

Both. We build new custom homes from the foundation up across Collin County, and we bring that same structural standard to every remodel, addition, and outdoor project we take on.
North Texas sits on Blackland Prairie clay that expands when wet and shrinks during drought, which is the leading cause of foundation movement in the area. For new builds and additions, we plan the foundation for that movement, commonly a post-tension slab on flat lots, and we pay close attention to drainage and grading so water doesn’t work against your slab.
A post-tension slab is an engineered foundation by design, built to handle the seasonal movement in North Texas clay, and we plan each foundation around your lot and its site conditions.
Both. Across Collin County, we build new custom homes in growth communities such as Princeton, Anna, Melissa, and Celina, and we remodel and add onto established homes in cities like McKinney, Allen, and Plano. The project changes with the area, but the standard doesn’t.
You get one project manager from EXL running your job from start to finish, and one company accountable for all of it, including every trade on site.
Because we price the whole job up front, and if anything changes once we’re into the walls, we write it down and price it before we do the work. No surprise line items on your invoice.
It depends on the size of the project, the materials you choose, and how much hidden work is involved. A small bathroom refresh and a full kitchen remodel are very different numbers, so we give you a clear, full price up front rather than a vague range.
Most bathroom remodels run a few weeks. Kitchens usually take longer, often because cabinets have a long lead time. Whole-home projects and new builds run longer still. We give you a timeline with your estimate and keep you updated as the work moves.
Usually, yes, depending on the project. For a single room or a bathroom, most families stay put. For a big whole-home job, we’ll talk through what makes sense. Either way, we phase the work to keep your house livable where we can.
On older homes, it happens. We tell you straight, show you what we found, and price the fix before we move ahead. You’re never surprised by a bill you didn’t approve.
Yes. We pull the local permits your project needs and handle the city inspections, so the work’s done to code and you don’t have to deal with it.
Yes. An ADU is a smaller second home on your lot, like a backyard guest house or in-law suite. We check your zoning and setbacks first, since that sets how big you can build, then design and build it to match your main house.
We back our workmanship in writing.
