"Allen Villacis Masonry came out right away and gave me a quote. They scheduled the work within a week and even finished earlier than expected. They were very accommodating and willing to use my old pavers. All the workers were polite and professional. Their price was very competitive and didnt change from what was quoted. I would recommend them and use them again for future projects."

"AFFORDABLE BASEMENT WATERPROOFING WITH A LIFETIME GUARANTEE! My basement walls had 3 cracks in them. They leaked water into the basement when we had heavy rains. To fix these cracks I called in top rated waterproofing companies for their estimates to do their repair work. I found these companies to be very expensive and give minimum time on their warranty's for their work, for the money you have to pay them! Then I found New York Waterproofing Inc. and owner George Carpozi III, George has been in the basement waterproofing business for many years and knows how to fix any type of basement water problem. He has waterproofed residential as well as commercial basements, fresh and ocean salt water problems, leaking basement walls, windows, joints, and water coming up through the basement floor. George can stop the leaks! He has his own system to do this without digging up outside your property! He is so sure he can fix your leak George gives a WRITTEN LIFETIME GUARANTEE on the work he has done for you. Who else does that? I hired George to repair my basement cracks, George and his crew came to my home the Sunday before the NY area had days of RECORD RAINFALLS last week. With all the rain we had, none of the cracks George repaired leaked! The pice I paid New York Waterproofing Inc, and with a written lifetime guarantee on the repairs they made, was about HALF the cost of the lowest estimate I received from the other waterproofing companies I called in! If you have any type of basement water problem, my recommendation is to call and get estimates, but DO NOT SIGN anything, until you call George Carpozi III, and New York Waterproofing Inc. You owe it to yourself, and your pocket! I don't know of any other basement waterproofing company who will give you a written lifetime guarantee on their work. I wish all with wet basements the best, and a happy dry basement to come as well, now go make that call!"

"I had John Whigham take care of waterproofing my basement. Everything about this project was just fine, from meeting with Bob to review the work and get an estimate through the completion of the job and the final work inspection. The John Whigham work crew were just great hard workers who took care of the job perfectly. They left the work site as clean as it was before they started. I would recommend John Whigham to anyone!"

"Eddie was great to work with! We had a limited time frame to adhere to town inspections and Eddie and his team knew exactly what we needed and quickly got the job done. The results were great and even the inspector acknowledged the impressive repair. They were able to put a knocked out garage wall back on the foundation and repair the interior dry wall. I would recommend this company for any professional contract work due to their reasonable price, ease to work with and quality of work."

"The Zavza Seal team were polite, professional, proficient. They removed tile from our Church basement fellowship hall and replaced with an overlay of colored painted and speckles over our existing concrete. The work was done with care and concern to produce the best possible outcome. They worked diligently to get the work completed to our satisfaction. Excellent workmanship."

"Really great experience with this company. We needed emergency repairs for a leak initially and they did such a good job we had them do some additional tiling work afterwards. Would definitely hire them again."

"It is with deep satisfaction that I recommend Gradys Painting and Plastering & Construction. Mr. George Grady is a skilled craftsman. He was hired to correct long neglected and extensive masonry and window issues on a large, beautiful Presbyterian Church built in the Civil War era in Philadelphia. The property was neglected with only minimal maintenance performed over the last 40+ years. The building was in severe decline and in need of stabilization and restoration on many fronts. Cracked ledge plates were chipped out and reestablished, internal walls damaged by leakage were broken out and repaired, brickwork was repointed and in severe cases reestablished to original strength and beauty. Leaks around the base of the building were addressed to stabilize deterioration of the foundation. Large rotted window sills under beautiful stained glass windows were restored after significant masonry reestablishment due to water damage under the rotted out sills. Broken and missing stained glass windows are in the process of repair and replacement. The process started with new metal frames cast by Mr. Grady. The new frames will hold clear painted replications of the original stained glass, also crafted by Mr. Grady. Regular windows all around the church and manse were also repaired and restored. Roof leaks were accurately identified and repaired. A sagging plaster ceiling has been torn out and restored. All this work was done by Mr. Grady alone or with an occasional helper. He worked with care, expertise and respect for the original structure. The results far exceeded our expectations and have injected new life into a building on the brink. This building, owned by the Presbytery of Philadelphia, now houses a new urban ministry in a newly gentrifying area of the city. We are happy to have had the good fortune to be connected to Gradys Painting and Plastering & Construction by Service Magic."
