What our customers have to say about us.

We worked with Stephen and his team on a window restoration project on a warehouse with original windows from 1933. The project spanned over the course of roughly 1 year. The total scope of the contract with Stephen's company consisted of 6 large windows. Stephen's company accommodated numerous bids and reviews of the bids with respect to complete replacement of apertures, renovation of existing windows. Ultimately we opted for a combination of restoration (1 window, 5' x 8') and the restoration of the remaining 5. Ultimately, we were very pleased with the workmanship and attention to detail on both the new construction and the renovation and can strongly recommend the contractor for either type of job. Project teams were very communicative and well received by tenants. They worked very professionally and safely with respect to lead paint abatement and working from heights. We will happily continue to work with Stephen and his crew when we have any future window related concerns

I hired Stephen Colvin and his crew to repair sash cords, and make and install storm windows for 12 wood windows on our house. The work was planned in the summer and completed by end of the the year following the time course initially projected. An email notice provided advance notice of each stage. The team that arrived was always punctual, and the work was performed with efficiency and great care. Interior areas were well covered in advance and cleaned after each work day. The crew are knowledgeable about wood frame windows and enjoy in their work.

I've worked with Stephen a couple of times now to do custom wood storm windows to enhance energy efficiency, reduce draftiness, and protect some intricate old leaded glass windows. Our experience with Stephen was excellent. He is a skilled craftsman and was always extremely professional. Highly recommended!
