Jim and James are master craftsmen. This was our second experience with them. We had them come back when our new stove was installed and required a Corian fix to make it all look perfect. We couldn't be happier with the way it came out! And they left the place cleaner than they found it too! Highly recommended!

Jim is awesome! So knowledgeable and kind. He helped me with some screw issues on a butcher block island/table top. The piece looks great!

Excellent work to repair two cracks in our corian countertop following the installation of a new cooktop. Excellent match. James thoroughly explained the process, reinforced the area around the cooktop and recaulked the area behind the cooktop. Highly recommend.

After 19 years, our Kohler kitchen sink, mounted under our Corian counter, rusted through. The Corian cutout does not fit any sink that is still being made! Jim Heaphy and his son at TopRepair told us that they could retro-fit a solid surface Corian double sink and adjust the cutout to match, and do it so that you'd never know it wasn't always there! And that is exactly what they did! In one day, they removed the old sink, brought in the new sink, re-shaped the cut-out hole in the corian, and made the new corian sink match perfectly with the old countertop! And it looks perfect, beautiful

Had two small chips in my quartz countertop by my sink. Top Repair came out and fixed them and I am more than pleased with the results. I would highly recommend them.

Jim and James did a perfect job repairing a prominent crack in our Corian just in front of the stove-top! We can't tell where the crack was, except, of course for the water damage on the cabinet below. That's the next repair to come! Corian repair is a messy, noisy, smelly job, but they did their best to minimize the disruption -- and the results are great! We are totally pleased!

We had the seam of our granite countertop lifting due to water damage. Rather than fix it, we viewed it as an opportunity to get the farmhouse sink we always wanted. We contacted Top Repair, took some measurements and exchanged a few pictures. They came in and got the job done in one day just like they said. They know what they are doing. Good people too. Hire them!

They repaired my cracked Corian around my built in stovetop. Both father and son were there working all day to repair 4 large cracks. They did a fantastic job and we did not have to replace our countertop. Cost a lot less to repair than replace.

Jim and James recently came to my house to do a repair on my 25 year old Corian countertop. The Corian had developed a 6 inch crack along a seam that extended through the decorative, elaborate countertop edge. I had my doubts as to whether anyone would be able to repair it so that the damaged area would not be visible. Jim and James brought many years of experience with them and were not only able to repair the seam but polished the adjacent surfaces so that they looked brand new! I would challenge anyone to find the previous crack, the work was done so well. They arrived on time and were very

We recently had Top Repair in our home to enlarge a countertop opening for a new cooktop. Jim and James Heaphy were both here to measure, cut, smooth and ensure our new appliance would work in the countertop. While here they also provided helpful info on countertop maintenance and care. They were professional and very knowledgeable about countertop materials. I would highly recommend their business for any countertop repairs or revisions.

I had a tile kitchen backsplash put in my house by another contractor, but while it was being put in my granite countertop got damaged. The other contractor did their best to repair the granite, but it was not up to my satisfaction.

I contacted many different contractors but they all said they could not do a better job to repair the granite.
Then I found Top Repair. Instead of refusing the job, they insisted that they could significantly make it look better. Just look at the before and after picture. They are very professional, and I would recommend them for any type of granite repair.
