Hi, I’m Jonathan — owner of Dallas Mastic.

I started Dallas Mastic because I kept seeing the same problem across DFW: homeowners with cracked, failing pool joints who couldn’t find anyone who actually specialized in the work. Most calls went to general contractors who treated mastic as an afterthought — wrong materials, rushed prep, sloppy lines. The job looked bad in six months and the water damage continued.

So I built a company around doing it right. That means proper removal, real prep work, commercial-grade Sika sealants, and finished lines that actually look clean. No shortcuts, no upselling work you don’t need.

What I hear most from customers is that I actually show up when I say I will and communicate throughout the job. That shouldn’t be a differentiator — but in this industry, it is.

Every job gets the same attention whether it’s a small crack repair or a full pool joint replacement. If you text me a photo of your pool joint, I’ll give you a straight answer on whether it needs work and what it’ll cost.
