From start to finish, we were happy with the entire procedure. We believe we received good value for our money by purchasing high-quality windows. Excellent communication and they also listen to our concern and very attentive as well. Very thorough installation and I was satisfied with the result. I will definitely use them again.

Great quality of windows! The use of Master Seal to analyze my needs and show me what solutions are available amazed me. They arrived on time and were really professional and courteous. They spent a lot of time explaining their items to me, the product was excellent and windows works excellently.

I recently purchased my SECOND Master Seal Door. it's a Storm door. My house is 70 years old so of course no standard door would fit. I chose a gorgeous color called Woodberry that matches the brick. When the installers set an appt they call and text you the day before and the day of TO LET YOU KNOW when you can expect them. They are professional courteous, friendly and PROMPT! After installation we noticed a minor issue.
We called and they sent someone out right away. The determined a solution to the problem. Today my door was fixed with the usual professional and very prompt service. I couldn't be happier with Master Seal. Their doors are not the cheapest, but the quality and the customer service are OUTSTANDING. Worth EVERY PENNY. HIGHLY RECOMMEND!

This company has high quality products, and excellent installation and service. I've bought three doors from them on different occasions. They show up and time and there are no surprises in pricing or service. The professional installer Ron Behr was outstanding. I highly recommend this great company!

Master Seal Installers rank among the best I've ever known. I am a retired carpenter and former owner of a home improvement company. I personally replaced this window and the 14 others in my home 30+ years ago. Other replacement window bidders excluded protection/restoration of the beautiful interior finishes for this window (see picture) above our Kitchen sink where we spend a lot of time when we're indoors.
I would estimate that the effort put forth to install this unit and leave the interior finishes intact exceeded 30% of the effort to install the other 14 windows that were included in the job. I rate the quality of the work, the skills of the craftsmen, their patience, courtesy, friendliness and diligence to be truly outstanding. Post installation we have had two service calls to correct malfunctioning window latches, and both were handled very promptly.
