I couldn’t be more grateful for this wonderful company. They went well out of their way to make sure I was taken care of properly. So much so, that when I was blocked in my garage by a fallen tree, Jason asked if I needed anything. That he would stop at the store for me, before he even got to my house to see if there even was any damage. The guys that came out to do the repairs fit me in to their schedule quickly. Their work was exceptional and they were very conscientious when they cleaned my driveway of debris. This is customer service and job workers who go above and beyond for their customers. I would recommend them to everyone who needs quality work and exceptional customer service. Thanks again you again for taking such great care of me.

Did another fantastic job on the roof. I am very pleased with the work. The installers and the project Manager Justin was awesome, I am a veteran and I am so grateful that they helped me out. Justin stayed with me for a couple hours, made sure the crew was on top of everything. I am forever grateful for him and Home Genius. This veteran is more than happy. AJ was phenomenal too, we talked about being in the military and we talked several times on the phone. Can't wait to meet him.

Signs Your Johnstown Home Needs New Windows

Johnstown homeowners should keep an eye out for these critical warning signs that a full replacement is necessary.

Visible Frame Decay and Structural Damage

Visible Frame Decay and Structural Damage

Widespread rot, warping, or soft spots on window frames are clear indicators that your windows' structural integrity is failing. In Johnstown and neighboring communities, exposure to temperature shifts can cause wooden frames to decay or vinyl to crack, meaning a temporary patch is no longer enough to prevent total failure.

Persistent Drafts and Poor Thermal Control

Persistent Drafts and Poor Thermal Control

If you are noticing air whistling through closed sashes, significant temperature swings near glass, or a spike in your Johnstown energy bills, your windows have likely reached the end of their functional life. When seals fail and allow unconditioned air to move freely into the structure of your home, a full replacement is the only way to ensure long-term comfort and energy efficiency.

Condensation Between Panes and Operation Issues

Condensation Between Panes and Operation Issues

If your windows are showing persistent fogging between the glass layers or have become nearly impossible to open, close, or lock, the internal components have failed. This level of mechanical and seal wear means your windows can no longer provide adequate security or insulation, necessitating a complete replacement to maintain your home's integrity.

Affordable Window Replacement Solutions

Transparent Pricing & Flexible Financing

We believe in clear pricing with no surprises for your window replacement. Every home in Johnstown is different, so the final cost depends on the number of openings, the high-performance glass packages you select, custom frame styles, and the complexity of the installation.

Our team provides competitive estimates tailored to the specific architectural needs of Johnstown homeowners, along with flexible financing options and a straightforward scope of work so you can make the right decision for your home without pressure.

Increased Property Value

Increased Property Value

Enhanced Energy Efficiency

Enhanced Energy Efficiency

Modern window systems utilize advanced Low-E glass coatings and argon gas fills to provide superior thermal insulation. By preventing heat transfer and eliminating drafts, new windows significantly reduce the strain on your HVAC system and lower your monthly energy bills in Johnstown.

Long-Term Cost Savings

Long-Term Cost Savings

While minor repairs or caulking may seem cheaper upfront, a full window replacement eliminates the need for recurring maintenance and temporary fixes. By installing durable, high-performance frames and seals now, you prevent expensive moisture damage and wood rot down the road.

Improved Home Comfort & Soundproofing

Improved Home Comfort & Soundproofing

Beyond just temperature control, new windows significantly enhance the daily living experience inside your Johnstown home. High-quality double or triple-pane glass acts as a powerful acoustic barrier, buffering your living space from neighborhood noise, traffic, and wind.

Superior Weather Resistance

Today I met with Sean w/HomeGenius for some windows and a door replacement. He went above and beyond on explaining the door and windows materials and make, also what options I had and how to go about getting things done. I was surprised and how genuine he was and toke time to explain things and make sure I understood what I am going to get done and the time frame in which it would be done. I would not be doing any home exterior work without going thru HomeGenius for doors and windows. I will give them a 5 Star all day. Thanks Sean H. n Team. Ray W.

We had our entire roof redone. We have solar panels, we were advised the project would include removing solar panels, when roof complete, reinstalling the solar panels. Plus they agreed to redo a portion of our living room ceiling. The panels were removed on Wednesday, Aug. 19th, 2026 - the roof completed on Thursday Aug. 20th, 2026. Today is Aug. 24th, 2026 and the solar panels have not been reinstalled. I have left 1 message by phone call, 1 message by text to the project manager and I believe Marc Bidic was a supervisor who I just left a text message to have our contract completed. I am hoping to hear something, but it is almost 4 pm and have doubts. The workers were great for the roofing, removing solar panels and we finally got the solar panels reinstalled on Wednesday, Aug. 26th, 2026. Solar is working. I feel bettet about the job, but individuals who are in charge need to pay attention to the work. I never saw a project manager until Fred visited us asking why I gave a low review. Money is tight for everyone, but to state step by step and me having to contact different individuals seems I only got attention when I submitted a poor review. The individuals who did the work are excellent and we just got our living room corner spackled and the two young men knew exactly how to handle the plaster and made it smooth so me and my mom can paint our ceiling. I hope management takes this job serious, cause to me there is not reason a week went by and we had low solar panels power.

My father woke up to water stains on his ceiling and immediately began contacting roofing companies for estimates. Within minutes of submitting his information online to Home Genius Exteriors, he received a call from a woman who was pleasant, attentive, and never made him feel rushed. It was refreshing to speak with a human rather than AI or an automated system, especially when dealing with an unexpected problem at home. An appointment was scheduled within 24 hours, setting the stage for what came next. Then we met William Flores. William arrived with a warm demeanor and a big smile, almost as if he were visiting people he had known for years rather than meeting my parents for the first time. He immediately made them feel comfortable. William listened carefully, answered every question and concern, explained their options clearly, and gave them the space to make their own decision. His approach remained the same throughout the visit. There was no rehearsed sales pitch, no pressure, and no attempt to sell my parents anything they did not need. He focused on what was necessary and worked with them to find an option within their budget. Watching William work made an impression on me professionally as well. As a Realtor, I could have recommended several roofing companies myself, but instead, I stood back and watched. After nearly 30 years in sales and customer service, I have encountered just about every approach imaginable. William could give a clinic on how exceptional customer service leads to a sale. He listened, connected, guided, and earned my parents' confidence without ever resorting to a hard sell. My father's reaction reinforced everything I had observed. Before William even finished the roof inspection, Dad was already canceling the other estimates scheduled for the day. His decision had been made before the appointment was even over. What began as a stressful morning ended with my parents feeling relieved and confident in their decision to choose Home Genius Exteriors. William, thank you for the kindness, respect, and genuine care you showed my parents. You are now familia, so please don't be a stranger! Knowing they were treated with such patience, and consideration means more to me than words can express. Five stars without hesitation.
