They worked thru the hottest day so far this year, with bo complaints and only showed there very best from set up to clean up. CAN'T FIND BETTER, that I've ever seen in a crew, or company...

Nagy Bros recently completed excellent work installing 25 Milgard Brand windows in my home - many were quite large. Rep Randy was fantastic! He was professional, knowledgeable and accommodating. He explained my options and provided detailed information; he helped with my window upgrade plan that was completed in 2 phases (fall 2025 & spring 2026) The install team of Scott, Dave, and Deana was impressive. They are definitely experts in their field - efficient with the install process and very capable dealing with heights and difficult window locations. I appreciate they did a thorough cleanup after each job. Lia the painter was meticulous with final touch ups. Rob was great. He monitored the difficult installs, and completed follow-ups and final inspections. One issue encountered was a manufacturer’s factory defect in one large window. A replacement order was promptly processed (through warranty) and a new glass pane was installed a couple months later in June 2026. My new windows have created an updated and amazing new look to my home. Nagy Bros provided outstanding customer service, a quality product, and exceptional results. I Highly recommend the Nagy Bros team. Elizabeth Carter

Jared was at our home yesterday to give us a quote on replacing some windows. He answered all our questions regarding construction and timing in the addition to giving us the estimate. We found him to be knowledgeable and we’re impressed with his presentation. We decided to go with this company.

I’ve had a great experience working with Nagy Brothers. Their professionalism stands out right away, and they actually follow through on what they say they’ll do, which isn’t always the case these days. Communication is clear, the work is solid, and you can tell they care about doing things properly. I’ve already recommended them to several people and will keep doing so.

The team at Nagy Bros was absolutely incredible! We recently had all of our home windows and sliding doors replaced. Jared took his time quoting the project and walking me through what to expect. Scott and the install team were professional, clean and efficient. You can tell they take pride in what they do. All of the finishings are top notch. Cannot recommend them enough!! Thank you all 🙂

Nagy Brothers installed all new windows for all the units at Creekside Villas one year ago. There are 3 condo buildings on this property. They were very professional, got the work done in a very timely and organized manner, consistent with what they had promised. The workmen that installed my windows were very informative and worked quickly to do the installation. They did a follow-up to make sure I was happy with the work done. I am very satisfied with the results and would highly recommend them to anyone needing windows. This seems to be the same feeling my neighbours had and any of the residents I have spoken to about their experience with Nagy brothers. Excellent job!

As both the resident manager and an owner of our complex I can say without doubt that the team at Nagy was absolutely amazing to work with. From a managerial standpoint they were quick and efficient handling everything themselves from scheduling units to corresponding with residents and access to the units. From an owners stand point the windows they installed have been a fantastic upgrade. My heating/ cooling bill has seen a decrease and the noise reduction is very noticeable. They were also very approachable and answered any and all questions ( I had many) with clear and responsive communication. I highly recommend Nagy.

As a contractor I've been buying windows and entry doors exclusively from Nagy Bros for the last few years. Their pricing is fair, product quality is great and their service is great too. I would highly recommend Nagy Bros to other contractors and to homeowners!

We had such a great experience with Nagy Bros on our full house project (22 windows and 2 door). Everyone we worked with was professional, friendly, and cared about doing a quality job. Our sales rep, Jared, was knowledgeable, approachable, responsive, and never pushy — which I really appreciated. The quote was competitive, and the installation crew (Scott, Dave, and Diana) were amazing. They worked efficiently, kept everything clean, and their experience really showed in the finished result. They were so kind and patient with my kids asking lots of questions throughout their workday! Rob was great with following up to make sure all the final tasks were complete. I’d highly recommend Nagy Bros to anyone considering a window project — they made the whole process smooth and enjoyable.

I had all my windows installed by Nagy Bros, and I couldn’t be happier with the experience. The entire team — from the owners and office staff to the installers — was friendly, professional, and courteous. The work was completed on time, and they left my home spotless when finished. They even followed up after the installation to make sure everything was perfect. Highly recommend! A sample of one window replacement. Before and after.

Frequently Asked Questions About Summerland Window Replacement

How much does window replacement cost in Summerland?

Homeowners should budget approximately $800 to $2,500 for each newly installed window in Summerland, which covers both the product and our expert labor. Your exact total will fluctuate based on the materials you select, the dimensions of the units, the caliber of the glass, and the complexity of the installation.

  • Frame Materials: Vinyl remains the most budget-friendly option without sacrificing efficiency, whereas fiberglass commands a premium for its unmatched rigidity and sleek look.
  • Glass Packages: Standard double-pane configurations provide excellent everyday performance, but triple-pane glass is the ultimate choice for extreme energy savings.
  • Installation Methods: Opting for a retrofit insert replacement is generally more cost-effective in terms of labor compared to tearing the window down to the rough framing.
What rebates are available for energy-efficient windows in BC?

British Columbia provides excellent financial incentives through the FortisBC and CleanBC Better Homes programs for property owners willing to upgrade their energy envelopes.

  • To be eligible, your replacement windows and doors must achieve specific Energy Star ratings and meet strict U-factor criteria.
  • The final rebate amount you receive is directly tied to the total number of qualified openings you choose to upgrade.
  • Nagy Bros eliminates the guesswork by giving you the precise manufacturer labels and detailed receipts required to successfully claim your funds.
Do I need a permit for window replacement in Summerland?

The District of Summerland typically waives building permit requirements if you are swapping out an old window or door for a new one of the exact same dimensions. However, if your renovation involves altering the home’s structure, you must secure municipal approval.

  • No Permit Necessary: Simple retrofit jobs or direct replacements that utilize the existing rough opening.
  • Permit Mandatory: Any project that requires cutting a brand-new opening, widening current framing, or shifting load-bearing studs.
  • Safety Standards: Keep in mind that any window installed in a bedroom is legally required to meet the egress size mandates dictated by the BC Building Code.
