What a fantastic job Dave did.
Everything right from Dave walking, he was courteous and the caulking was done to perfection.

You are a life-saver!
Thank you so much for doing such a fabulous job!

After we made the terrible mistake of hiring an inexperienced general contractor to replace the caulking around the windows and doors of our home, we were disappointed and very upset. Not only did you remove and repair the mess that was made by the previous contractor, you went the extra mile and made our 8-year-old windows look brand-new.

Your crew arrived on time, they were fast, efficient, professional, courteous and friendly, and left the site clean and tidy.  It is obvious that you take pride in your work.  We are proud of our home and, happy to show off your fabulous work.  We’ve already recommended Costa Caulking and, we will gladly recommend you to our family and friends again and again. We are so happy with the professional job that you did.

The extra touches such as adding a bead to all the vents and outside electrical outlets, the basement windows, and to the porch above the cantina were beyond the original scope of the job.  We really appreciate all the little extras that you gave us without hesitation.

Thank you so much for your help.

Costa Caulking was, without a doubt, the perfect choice for re-doing the caulking on my house. They exemplified professionalism right from the point I placed the call for a quote, to the point the truck pulled away from the house when the job was done. Excellent quality work. I highly recommend them.

My advice is look no further. This is the company to do business with. First, David is very honest. He came to provide me a quote. When I asked him, he told me my windows caulking can last another year. I chose to do it this year anyways. Also he told my neighbor he can wait several years. This tells me that he is horniest. Secondly, his quote is competitive. Lastly, his crew is professional. They arrived on time, the work is done very nicely. They cleaned up the garbage. I had a chat with the crew, they told me David is the best. Payment is done professionally as well. He’ll email me the invoice, I’ll mail him the check. Everything gives me the comfort feeling when dealing with this company. Thank you David.

David Costa provides honest, professional and competitive service. The phone is always answered with courtesy and promises are kept. His employee Robert, was meticulous and actually took the time to caulk an area that was not included in the contract. We would wholeheartedly recommend Costa Caulking without hesitation. Thank you David and Robert

Myself and two neighbors used Costa Caulking for all our windows and doors. We are all very pleased with the professionalism of Dave and his crew. The job was completed quickly and very neatly. Highly recommended.
