"We had a wonderful experience with Coldstream Exteriors. Last year our roof was looking pretty rough. We called Coldstream Exteriors. They came out and looked at it the next day and determined we needed a new one. Ricky Waller worked with our insurance company and got us the best deal possible. He also supervised the roofing crew, who were also amazing. They were very respectful and thorough. The crew Cleaned up after themselves and Ricky came back the next day to check our roof, for stray nails on the ground and to make sure we had a good experience. So when we decided to replace our gutters in September there was no question that we would call Coldstream Exteriors and ask for Ricky Waller. He had his crew out in just a few days. Start to finish was only 3 hours. They installed gutters and gutter guards. Besides being knowledgable they are the nicest people to interact with. They were very respectful of our home and flower beds and no mess after. Again Ricky waller came out after to check installation and for way word nails or screws. I would highly recommend Coldstream Exterior and especially Ricky Waller"

"I used H&F exteriors to install windows in a 130 year-old historic property. The old windows were crusty and inefficient. The new windows are great, and have cut the heating and cooling bills in half. H&F and their team were terrific to work with, honest and responsive."

"Amazing! We purchased the wrong item. Not only did he advise what to buy. He found it sent us a link and contacted us immediately when he arrived. Then the work he did when he got here was on point. No surprise costs either. Over communicated. Highly recomend"

"We looked at four companies to install a new furnace and Total Comfort offered the best product at a very competitive price. The crew that installed the furnace was excellent and the County inspector who inspected the completed installation gave the installation crew high marks for the quality of their work. I will highly recommend this company to anyone needing a new furnace."

"It was great. They came out, they showed us all different kinds, and we picked out what we wanted. They came back out within two weeks. They make the windows themselves so that you don't have to go to a separate factory. It was a very nice experience. They took out literally a wall in my living room for the bay window. They had them installed. They took out the sliding glass door in my kitchen which had to be special ordered because it was originally a french door that was converted into a sliding door. They did both of them in the same day and quickly. It didn't even take the whole day. They showed up promptly and got to work right away. They were done before 2 in the afternoon. That's not even that generous on the time. They were just bam, bam, bam. I would recommend them to anybody."

Eifs Installers questions, answered by experts

New window installation costs range from $300 to $1,500 per window, depending on size, material, and energy efficiency features.

Adding windows to a house is expensive. Budget roughly $5,800 to add a single window, and double or triple that to add two or three. In some cases, adding a single window can exceed $20,000, depending on the type of exterior wall, the size of the window, the type of window, local permit costs, and other factors.

Egress windows require regular maintenance to ensure they function correctly. This includes cleaning the glass, inspecting the frame and well for debris, and making sure the cover or well drains properly. It is also important to check that the window sills and wells are watertight and to inspect and repair any damage to the window frame or seals to prevent leaks and maintain functionality.

The entire window replacement process, from the initial consultation to the final installation, typically takes between four and 15 weeks. This timeline accounts for measuring appointments, ordering, and manufacturing. On the day of the job, the physical installation takes about 30 minutes to two hours per window. A full-house replacement can take one to three days to complete. Factors that can extend this timeline include the total number of windows, custom sizes, complex window types, second-story installations, and any necessary repairs to existing window frames or openings.

Yes, you can install a bay window in an existing house. You’ll need to have a structural engineer draw up plans to add the necessary support to your exterior load-bearing walls and a general contractor to make the changes to the framing around the new wall opening. This will cost an average of $3,000. After that work is done, a window installer can set the new bay window in place.
