The family behind it
The name on the truck is the name on the job.
Grech Family Construction is exactly that — family-owned and owner-operated. Patrick Grech is hands-on from planning to the final board, skilled across framing, electrical, plumbing, concrete and finish carpentry, and he treats every project like it's his own home.
It's a deliberately small operation built on clear communication, honest pricing and craftsmanship that's meant to last. When you call, you reach the person who'll actually be on your site — and who answers for the work when it's done.
Patrick built a deck for me, and it is a Masterpiece! Professional and personable — I am saving up to have Patrick and his crew do some more work.
