What they say about us.

Gavin and Apex Construction made the build experience on our home an easy and pleasant experience. The team were consultative in their approach and they stood by their work.

Aaron Miller

Gavin Mandt at Apex Construction made the home building process a dream. Not only was he proficient and professional, he often acted as a consultant by offering feedback on our plans and our ideas. The result of his experience and guidance was our dream home.

Tiffany Dennis Miller

Gavin Mandt has a strong work ethic and shows impeccable management skills with his subcontractors. Keeping calm under pressure and digging into a job when it's needed is very impressive. Great things are on the horizon for this home builder.

I have worked with Gavin and Apex on numerous projects and have recommended them, and will continue to recommend to anyone that wants quality workmanship at a fair price and timely completion

Jack Mueller

Gavin Mandt and Apex Construction are the best! Over the last 2 years they have done multiple projects on my 1950s era home, inside, outside, room addition, fencing...they’ve done it all! The quality is outstanding, they look for ways to save their customer money without sacrificing quality, and they listen to their customer’s wants and needs. They are the best in Grayson County and I wouldn’t trust my home to anyone else.

Gavin is an outstanding general contractor, and I would highly recommend him. I was in a real mess on a rental property rehab, and Gavin jumped in half-way through, took over the job as GC, did all of the work correctly the first time for a fair price, and then navigated a difficult inspection and approval process to get the property back in service.
