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.
