From the time I contacted the company and spoke with Rob , I knew I was going with the service. House was very drafty and windows were sweating. Rob came by personally and did the quote for me and explained the process so I knew what to expect. Tech came the next week and did all the windows, doors and around the laundry vents and even the garage. Have noticed a big difference in heat retention in the house now and windows have stopped sweating. Highly recommend costa caulking!

Our bathtub needed re-caulking. From past experience, I knew that my high expectations for a smooth, even seam would be met by Robert, a master craftsman. He did not disappoint. Nobody does it better!
Thank you, Robert.

Read the reviews, scheduled the work. Costa Caulking did the work, it was even better than I had anticipated.

Exceeded expectation on scheduling, exceeded expectation on work performed.

I want to thank Kevin and his crew for the 2nd time who did caulking at my first house as well, they are very professional, polite and do great work. You can be sure that the work gets done properly and the price is reasonable, I highly recommend Costa Caulking there is no gimmicks considering that there are so many contractors nowadays who cut corners and do shotty work.

This is the second time Costa Caulking did work for me. They did a fantastic job on my first house years ago. This time Im calling them directly without asking anyone else. Kevin promptly provided me with an estimate and advised me little things I missed. Peter, the technician, patiently explained the work to me. He did a great job too. He was nice, on time, and polite. The quality of work is great, site is clean after the work done, I am very satisfied.

Costa Caulking delivered a very positive experience every step of the way!
They were right on time and very professional in their work.
The installer was extremely polite and respectful of us and our home.
The end result was amazing.
We have a lot of stone work on our home and all those little nooks crannies were sealed perfectly.
All of our windows and doors look brand new!
It is always reassuring that when your hire a contractor a professional shows up to do the work.
Costa Caulking are definitely professionals.

Very professional service, Dave is very knowledgeable, informative and a pleasure to talk to. Peter the installer was great he went above and beyond my expectations for the project. I would definitely use them again in the future.

I was so pleased by the work done by. Costa Caulking. Armando did an excellent job and was very pleasant and worked diligently all day. Everything was done to perfection. Robert who was also very pleasant came and helped out for a couple of hours with very high, hard to reach areas. Both excellent workers.

I couldn't agree more with all of the positive comments about Costa Caulking, and especially Peter, the technician. He was patient as we tested and finalized colour decisions, courteous and highly skilled. He also offered to come back to fix a bead at my front door that my todler destroyed an hour after they left the job! I am really really glad I went with Costa and would definitely recommend them to others. I have never left a comment for a company on homestars before, but these guys definitely deserved it!
