"Jamen was prompt in returning my call for a quote and his prices were very reasonable for installing some ceiling fans. He was thorough and did a great job!"

"Patrick is friendly, but the workmanship is poor. I hired him for two repairs, and both were done inadequately. The first involved exterior trim. The trim was replaced, but the caulking was incomplete and never corrected despite raising the issue. The final cost far exceeded the initial estimate. While on the roof, Patrick and his partner also damaged my new shingles. That repair alone cost nearly $3,000, which they paid only after I threatened a small-claims court filing. The second project?repairing loose chimney bricks?was also done poorly and left unfinished. Mortar was slopped onto the bricks, the bricks are still loose, and there is no mortar cap. I requested a refund since the work must be redone by a qualified professional, and it was refused. Do not hire. The only reason I learned of the extent of the damage and the substandard work was that roofers later documented it."

"Great service and the assembly work was done perfectly.."

"Devin was so professional and knowledgeable. Great company and service!! Highly recommend."

"I dealt with Ken from beginning to end. He was prompt, professional, knowledgeable, and very skilled! Our new front and back doors are gorgeous, well made, and installed with perfection. Our back door jamb was not plumb and Ken spent time and energy to ensure that our door was installed properly. I appreciate the quality and attention to detail. I would definitely recommend using them."
