Worked quickly and did a good job. Professional and friendly service.

Very professional from estimate through sealcoating. 100% recommend Chad & his crew.

Yes great service and the work looks great! Super nice people..

Very congenial and professional. Did a great job. Would absolutely recommend him

They were fantastic! On time, friendly, professional,and high quality work and craftsmanship. I would definitely recommend and will be hiring them again. They did our landscaping and driveway and very fairly priced. We'd give them 6 stars if we could

I would highly recommend. The customer service and quality was excellent.

Weâ re on time. Very neat clean job. Several more neighbors have hired them after seeing my driveway.

Did a great job. Very personable and easy to work with. He was the only bidder to come to the house and actually look at the work to be done before bidding would hire again.

Well done

They ran out of seal coat twice, job was not done properly Not a smooth finish I called, sent pictures, they promised they would come back and fix, Yet they never returned, nor have I heard from them since Would not recommend Driveway was a fresh repair , one yr ago. Now it is cracking and I will have to invest more money to repair

Chad did a great job, kept us informed about when he would come to do the job, was careful to keep the sealant contained to the work area and not on the grass or sidewalk. I highly recommend Costello seal coating as they were very professional. Also, heâ s local and I prefer to support local businesses

Work was done as if they were doing there own

Kept us informed with his progress , always asking if we had any questions, completed the job with professionalism. Would recommend him to others.

Yes very efficient and great communication.

Chad (owner) was very quick in response to my inquiry. I received his co info from another client that was very pleased with their work. He was VERY thorough on what he saw as to the repairs we needed. Noticed cracks. Explained how he took care of it. Explained his warranty on the work. Heâ s licensed and bonded so that alone tells you he is PROFESSIONAL. We have a contractor (residential remodeling) comp and get people asking us all the time if we have a referral. Chad offers many more talents. I will pass his info that for sure. (His wife is as sweet as can be. )

This guy is the best they I got my quote it was very fair he came out within the week and had the work done within the week and it's look perfect I will be using them again.

Good Customer Service.

quality job

Great job and great communication

Excellent service. Kept us informed of revised schedule due to weather difficulties.

Excellent job. Iâ m impressed with the way Chad answered texts and phone calls. Showed true concern about my problems and situation. I would recommend Costello Sealcoating to anyone that wants a timely, professional job done!!!

What a great experience very professional

They did a great job at a fair price. Done by hand, not sprayed on.

Chad and his crew did the best seal coat I have had in 30 years on our driveway . He was knowledgable, personable and gave a good fair price for the work performed. I will use them again next time without reservation. Did a great job!

Does great work, explains everything clearly. Will work with them in the future
