Have you ever gotten an estimate or from, or a large remodeling company that was overpriced? Mark Dziengiel, owner of DZ Renovation was a Vice President at a 75 million dollar, nationally recognized company. We know this industry like the back of our hand. There are too many multimillion and billion dollar remodeling companies overcharging consumers for premium remodels. DZ Renovation was founded on the same business model as the large companies everyone has heard of. We carry the same ultra-premium and custom made products, with factory trained installers, competitive financing, and all-inclusive lifetime warranties; without the massive markup. We are not the small remodeling company taking shortcuts to be the lowest bid, we do everything meticulously and only offer products we would put in or on our own home. We will be far from the highest priced company you can hire, while delivering highest quality service.

"Full house gutter replacement. Nick was 1 of 5 sales personnel that came to my home to present and gave me a no hassle free estimate, he left a lasting impression, months later I call to sign the contract and proceed, believe it or not he was the only salesman my wife remember because he was so professional, knowledgeable and respectful. From the time I signed to the time the work was completed was less than 1 week. The installers were awesome, couldn’t ask for more. I definitely recommend DZ renovation. Mark call after completion to make sure all went well. Thank you DZ. I can rest assured that water from my roofs is well controlled. "

Windows questions, answered by experts

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.

Yes, you absolutely need a permit to add a window to your house. Your contractor can likely obtain this permit on your behalf. Ask about this when getting quotes from multiple window contractors.

If you decide to forgo your old windows and upgrade them to modern day technology, there may be some people interested in the old windows. You can try selling them on an online marketplace for around $50 to $100 each (so long as the window wasn’t damaged during the removal). This can also help off set the overall price to replace them.

While all windows require some maintenance, vinyl windows are the least hands-off. They’re easy to clean, weather resistant, and extremely durable. If you like the look of wood windows but hate the price tag and high maintenance requirements, you can add a faux wood finish to vinyl as well. 

Replacing basement windows can be worth the cost if replacement is necessary. If your windows are leaking and leading to water damage in your basement, it’s absolutely worth replacing them. Similarly, if your basement windows are no longer insulating your basement or pose a security risk, you need to replace them.

In some cases, you may be able to save money by repairing a window instead of replacing it. A contractor can help you decide the right course of action.
