"Kenny and team were amazing to work with - professional, polite, honest, and finished the project ahead of schedule and at a very fair price. We had two old single pane windows replaced in our basement (which may have been 50+ years old), and a new window well installed. The work was very well done. I have since recommended Clifton to multiple friends and other contractors. Five stars."

"Our sliding glass door was barely sliding – dragging would have been a more accurate word for it. Moses diagnosed the problem as more than just the need for new rollers, showed us where the track was excessively worn, obtained what was needed to repair the track rather than trying to replace it, and now our door rolls smoothly again. We are very pleased."

NOVA Exteriors, Inc. is a 12 time Angie's List Super Service Award Winner in several categories. We specialize in exterior remodeling and have over 50 years combined experience in the Metropolitan Area. We take pride in our work and we would appreciate the opportunity to showcase our services.

"NOVA Exteriors did a wonderful job replacing 3 exterior doors at our home. They checked every box one could ask for. Rob our sales rep was patient and understanding of our needs - even coming back a second time as we had a hard time deciding on what we wanted. Their team worked quickly and did a great job installing some beautiful new doors. We noticed after the installation that there were some imperfections on the hardware installed and they have agreed to replace them & their customer service was top notch. They responded quickly to some minor concerns and went above and beyond to fix the problem. While doors are never cheap, their price was right in line with other Provia vendors and 1/2 the price of Pella vendors. I'd highly recommend them."

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

Window replacement in Frederick enhances comfort by reducing winter drafts, blocking summer humidity, and improving indoor air quality. New windows can also reduce outside noise from busy local streets and boost curb appeal, especially in historic neighborhoods. Improved insulation supports lower energy use, while modern locking features add security. These upgrades make Frederick homes more comfortable, efficient, and aligned with local preservation values.

Helpful?

After window installation in Frederick, schedule any required inspections, especially if your home is in a historic district. Test all window locks, check for smooth operation, and inspect caulking for airtight seals. Establish a seasonal routine—clean glass, check for drafts, and watch for condensation during MD’s humid summers. Keep all permits and warranties organized, and monitor energy bills to track improvements in efficiency.

Helpful?

Homeowners in Frederick should consider historic district guidelines, which often require specific window materials and designs to maintain neighborhood character. The region’s variable climate means choosing windows with strong insulation and storm resistance is key. Window installation projects typically require permits, and egress standards are enforced for safety. Planning around Frederick’s spring pollen or winter weather can help avoid project delays.

Helpful?

For Frederick homes, prioritize safety by installing window stops that meet local code, opting for laminated or tempered glass on lower floors, and selecting pet-resistant screens for added durability. In older homes, check for lead paint before starting any window replacement. Choose window styles that limit how far they open, and always keep tools and materials out of reach during installation to ensure a safe environment.

Helpful?

In Frederick, window replacement or installation can impact nearby electrical wiring, HVAC airflow, and even original framing—especially in historic homes common to the area. Before starting, check for hidden wiring or ductwork near window openings. Upgrading to energy-efficient windows may also change how your HVAC system operates. Consulting a local window contractor familiar with Frederick’s housing stock helps prevent unexpected disruptions.
