"I called GSM inquiring about their HVAC and insulation services. I also asked if I could have someone perform a Manual J load calculation (surprise to me, the Manual J calc was free!) as I felt that my existing heat pump was sized too small for my home (2.5 ton dual-zone single stage heat pump for 2200sq ft 2-story house). We agreed on an appointment time, and they sent Kelly out to my house. Kelly was very nice and professional, and did a thorough job explaining what all could be done and what my options were. Due to having so little room to work inside of the mechanical closest, you would have to remove the air handler completely just to wrap all of the duct work. Since I would be removing the old air handler that was 8 years old anyway, I decided to replace the entire system with a new Amana 3-ton 18 SEER dual-zoned heat pump. Kelly also told me they could seal up the hole & the mechanical closet so that hot air could no longer enter that space as well. I agreed to their quote, and they came out a week later (it would've been sooner but GSM wanted to make sure that the new system was designed properly, so they had to architect and design the layout of the new equipment to fit the small space) to do the work. Owen and Jason came out to perform the installation. They were both very professional & thorough, and they did an excellent job with the swap out & installation of the new heat pump. When GSM told me that it would take two days to do the work, I was prepared to be miserably hot trying to sleep at night with no air conditioning. Not only did GSM bring a portable AC unit for me use that evening so that wouldn't be the case, Owen and Jason actually got the heat pump wired and working the first day so I had full AC that evening, and the portable unit wasn't needed! They also insulated the attic space & mechanical closet with spray foam and foam board so the hot attic air will no longer be an issue. All in all, my experience with GSM has been great! They've been easy to communicate with throughout the entire process, they did an excellent job with the installation of the new equipment, and now I can rest easy knowing that everything has been taken care of!"

"Very satisfied overall with the installation. Only issue I had when installers left was that the humidity sensor in the crawlspace didnâ t work. This was a very minor issue resolved with replacing a couple â AAAâ batteries."

Eifs Installers FAQs, answered by experts

Finding a reputable contractor for an egress window installation involves researching and vetting potential candidates. Start by searching for local professionals, reading customer reviews, and checking their websites for a portfolio of their work.

Once you have a shortlist, ask the following questions to ensure they are qualified:

• Are you licensed and insured?

• What experience do you have installing egress windows?

• Can you provide references from previous customers?

• Do you perform the work yourself or use subcontractors?

• What is the estimated project timeline and your current schedule?

• How do you handle payment?

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.

Basements are generally required to have windows for your safety. At a minimum, windows should provide an egress in the event of a fire. But basement windows do more than offer a way out; basement windows also offer natural light and ventilation in an area of your home that is otherwise dark and musty.

Most professionals can install a window well in two to three days, depending on the size of the well and the window you want inside it. If you’re just replacing an existing window well, the work is much less intensive, and most experts can get the job done in just one day. Connecting the window well to a drainage system or installing a custom concrete window well will naturally take longer, but even the most complicated installations shouldn’t take more than three days.

Yes, you can always make an existing window bigger, but the job complexity varies widely depending on the location of the window and the framing around it. Exterior walls are always load-bearing, so making windows wider will require structural changes that make for a more complex but doable project. Making windows taller often won’t require structural changes.
