"This team is amazing - I cannot underscore that enough! After my family member became disabled due to an accident, we needed accessibility modifications made to our home. AIP completely restructured a fairly small existing bathroom into an ADA-compliant bathroom with roll-in shower stall that is beyond what we had even thought possible. They had knowledge of and experience with specs and features that would be necessary for someone in our family’s situation - many of them details we didn’t even realize we had to consider. AIP were meticulous about sticking to their work schedule as promised and finished the job LITERALLY TO THE HOUR that they promised it would be done. They even left the new bathroom and their workspace sparkling clean and ready for instant use. Perhaps best of all, they demonstrated consistent care and compassion for our family as we made our way through the early weeks of our sudden and sad circumstances. I recommend them over and over again"

45 years of experience
Colonial Restorations is a father/son company. We use no subcontractors so at least one of us is always on site. Since 1981, Colonial Restorations has provided structural restoration and repair of historic timber frame buildings. A family business, Tom and Brad Green perform all work themselves in order to make sure that your historic timber frame project receives all the experience and commitment it requires.
"Barn Rescue – My barn was hit by a vehicle, which broke a large post and pushed section of siding out from under the roofline, plus major damage at ground level. Brad shored it up for the winter with an array of jacks and an enormous chain to ensure the thing wouldn’t fall down till they could return in the spring. Come spring, they fully replaced the damaged section’s support members and facade, and added bracing to the attic, rendering it stronger than before. Foundation support: The sagging beams and jerry-rigged support columns in the dirt basement of our 18th century house were inadequate. They dug and poured a dozen footings and lally columns, supporting a line of new 6x6 and 9x9 beams that provide solid support to the house above. They showed up promptly every day, worked fast, and left the site clean and finished. Both Brad and Chad have a deep knowledge about old houses and the techniques that were used, and I felt my historic register property was in good hands."

"Well the contractor like most contractors seem interested to get the job until of course they got the job then their customer service changed. HomePros never pulled a permit which they said they would. 75% of all worked preformed had to be redone a second time because of the poor workmanship and finished look of the job. Here is a few of those items. Ceiling, interior wall, exterior wall, and they ordered the wrong window size as well. The owner Randall spent very little time at all on the job site and was very difficult to reach once they had been given the job. The quality and fished product did not match the work that was advertised on their website. Ultimately I signed off on the job as happy however I would never higher this company again and would greatly advise those against it. The owners son was however very professional and took extra time and effort to correct the poor finished look of the work that the supposedly experienced worker was done with. His customer service is what convinced me to sign off on the job as done and satisfied. There was nothing else they could do to make it better so it didn’t make sense to me to drag out this job. In closing I would say at very best this company is capable of handyman work but not anything close to a full remodeling contractor. Buyer Beware!!’"
