I am a very satisfied repeat customer of Accurate Custom Sash. The professionalism and workmanship they provided is unmatched.

They took the time to layout and install a door opening that I was told could not be done. It was a pleasure to work with such a knowledgeable and courteous staff.

I will certainly call again for any future work, and would highly recommend them.

I want to tell you how pleased I am with my recent window replacement.

Your care was evident at our first meeting and your craftsmanship was apparent when my windows were installed, and continued through until installation.

My new wooden storm and screen windows have earned me many compliments. When my kitchen and bath needed new windows, you combined ideas and know how to provide me with windows appropriate to a 1920s bungalow.

I am always happy to tell anyone who did this work, because you and your company provide a level of craftsmanship and caring that is not common today.

Our family room in our home was very dark because we did not have windows... We consulted with Accurate Custom Sash and decided to install windows in our family room. The brick outside was removed and the windows went in.

We are so pleased with our new windows. They look as though they were always a part of our home.

Frank and Debbie Calace

We were so impressed with Accurate Custom's attention to detail, from the estimate... to the completion of the project.

We are very pleased with the results, and have received many compliments on the quality of craftsmanship, even from other tradespeople.

We look forward to working with the nice, professional people at Accurate Custom again!

Mark really knows what he is talking about. I have Biltbest windows and needed repair parts. Mark took the time to talk with me on the phone and he described exactly what I had and what I needed as if he were standing next to me looking at my windows. The correct parts were sent to me right away, and with the step by step instructions included, the entire repair went perfectly.
I am very satisfied with the service!

I would like to take a moment to thank Mark for using his valuable time to find a door lock replacement for me. I visited every home improvement store in the area yesterday. I even had one employee tell me that I would have to buy a new door. I had almost given up hope of finding what I needed. Dave Merry from Southland Log Homes, where we purchased our home referred me to Mark. He worked back and forth with me all morning until he found the part I needed.
Thanks again Mark for your help. Have a great day!!

Thanks Mark for the wonderful job you did to rebuild my window locks. Now I'm considering sending you my other ones that aren't broken - just so they all look as great! I was surprised how quickly you completed the repair and returned the items to me. I also appreciated your call when I placed the order, and again after I received the locks to make sure everything was ok.
I'm pleased to recommend you to others! Thanks from your Iowa neighbor.

"Hello Mark. Hope all is well with you. Mark, I am just getting around to my window repairs, and have found your rails and stiles to be "FLAWLESS! Your millwork is more consistent and of higher quality than the manufacturer.... Thank you for that!"

"We bought our 1991 home a year ago and soon discovered that the Biltbest windows were in bad shape. 21 years of weather and lack of maintenance had taken their toll. The seals were shot and our energy bills, we soon discovered, were through the roof. You could actually hear the wind whistle through most of the windows and feel the drafts. Not good in a Colorado winter or summer.
Replacing all the windows in the house would have been extremely expensive so we started looking at alternatives and found Mark and Accurate Sash.
I cannot speak highly enough about the products and service we have received from Mark and Accurate Sash. With Marks guidance and expert advice I ordered and am installing all new vertical/horizontal/leaf seals and replacing damaged hardware and wood as needed.
The cost of repairing what is essentially a very good window in need of maintenance is a fraction of replacement cost. It is my opinion we will recoup the cost of repair parts in only one or two months of energy savings.
Thanks Mark and Accurate Sash! You really stepped up to the plate for us!"

Just a note to say glad I found your site again, searching the internet. I purchased some BestBilt parts from you a few years ago to fix my casement windows and was in need of two more. I placed the order this morning and figured I would get a couple of extra, being I have fifteen on these in the house. When I came and picked up the original order a few years ago, I remember meeting you personally and you taking the time to explain how to replace the units. Your knowledge and professionalism is above anything I have ever experienced! Thanks for all your help.

I wish I had more business that I could do with you. If all vendors offered this kind of service, the world would be a better place."

“Can’t thank you enough for supplying the hinges for my casement windows!  My carpenter just finished installing the new hinges and they are wonderful!  Install with your excellent instructions went smoothly.  Not to mention the thousands of dollars saved by not having to buy new windows.  I highly recommend Accurate Sash.  Your customer service is excellent.  Thank you again.”


Thank you for being there!

"We installed the restored Pella casement sashes today (stained and varnished) and they fit perfectly. My finish carpenter was thoroughly impressed and now has your info for his clients. Thank you for saving my windows and making this repair possible. I couldn't be happier with my windows or Accurate Custom Sash and agree that you "are the experts". I am so relieved to have my home ready for winter.
