What Maryland homeowners say

⭐⭐⭐⭐⭐ Excellent Service, Professionalism, and Quality Work! I had an excellent experience with Apper Construction! From the very beginning, Leandro was professional, friendly, and attentive. He took the time to answer all my questions, explain the process, and provide clear information about the work and pricing. I contacted them regarding the installation of a roof vent for my bathroom exhaust fan, and I couldn’t be happier with the experience. I also want to recognize the technician who performed the installation. He did an excellent job, worked professionally, and made sure everything was properly completed. I truly appreciate his attention to detail and the quality of his work. What stood out to me the most was the excellent communication, honesty, professionalism, and dedication to customer satisfaction from start to finish. Thank you to Leandro and the technician for making this such a positive experience. I highly recommend Apper Construction to anyone looking for reliable service, quality workmanship, and a team that truly cares about its customers. I would definitely hire them again!

We were in need of a new roof and there was a time limit on it due to a horrible insurance company, you know the one that’s “on your side”, but they’re really not. I had at least four roofing companies come out and give me their speech like they do. For the fifth company, I dialed the wrong number that day and somehow by the grace of God a gentleman answered by the name of Leandro who owned a roofing and construction company. What are the chances? I Explained my situation and he came out the very same day to check out the roof which was 4,400 sq.ft. Mr. Leandro was so professional and answered all of our questions. Just listening to him speak about the procedure for a roof replacement was remarkable. Needless to say, he and his employees got the job! My roof was replaced even with new plywood, in one full working day. Mr. Leandro brought nine workers starting 7 AM and leaving around 6 PM. Once the Job was complete, you would’ve never known they had been there, which was so impressive. They had tarped everything, blew gutters out, and used a huge magnet to make sure there were no loose nails laying around. Throughout this whole ordeal, did I mention the price was very very fair! God Bless You Mr. Leandro and your hard-working employees!

From first meeting until job completion Apper was responsive, punctual, and expertly professional: highly recommended for vinyl siding replacement. The company owner showed personal interest by doing the initial estimate, checking work progress, and asking my impressions as work progressed. The 5-man crew operated efficiently, with well orchestrated precision, completing the job with excellent results in 2-days. Apper Construction is the place to start for expert vinyl siding replacement at a fair price!

Strongly recommend Apper construction for any roof and exterior needs. Noticed a leak on Sunday, they were out on Monday to assess and give a quote. Leandro and his team were impressively thorough and they did a great job. Very thorough cleanup too!

Gambrills' colonial subdivisions — Two Rivers, Walden, Andrews Mill, Saddle Ridge, Conway Forest — were built mostly between the 1990s and 2010s, and the windows that came with them are now doing exactly what builder-grade windows do at this age: the argon has bled out of the sealed units, the weatherstripping has hardened, and the early vinyl frames on the oldest of these homes are starting to fog with failed seals. On a big two- or three-story colonial with a lot of glass, that adds up to real money on the BGE bill and a house that never quite holds its temperature through Maryland's humid summers and cold winters. We replace those tired units with ENERGY STAR double-hung, casement, and bay windows carrying Low-E glass and argon fill, sized and styled to fit the way these colonials were designed. The efficiency gain is the headline — cutting the heat transfer that drives heating and cooling costs — but on Gambrills' larger homes the comfort difference is just as noticeable, especially on the tall gable-end walls and the two-story foyers where the original builder windows leaked the most air. Because so many of these homes share the same builder floor plans, we've replaced windows on plenty of them and know where the flashing and sealing shortcuts tend to hide behind the trim. We inspect every opening rather than quoting a blanket price. Where the frame and sill are sound, an insert replacement keeps the trim and interior finish intact; where there's rot or a failing original frame, a full-frame replacement lets us flash and foam-seal the opening properly instead of trapping a future water problem behind the new glass. We match the sightlines and grille patterns so the new windows read correctly on these colonial elevations, which also matters for the HOAs — Two Rivers, Walden, and most Gambrills communities run architectural review, and we prepare and submit that paperwork so a window swap doesn't run afoul of the board. Every install is done by our own local crew, backed by a written workmanship warranty, and permitted through Anne Arundel County. As a licensed window contractor in Gambrills, we handle full-frame window installation and replacement.

Most Gambrills window projects run about $650–$1,500 per window installed, or roughly $10,000–$30,000 for a whole-home replacement, depending on size, style, and whether an opening needs full-frame work. The larger Two Rivers and Saddle Ridge colonials with many openings and tall gable walls sit toward the top of that range. You get a written, line-itemed estimate — including any full-frame and flashing work — before anything is scheduled. Call 410-508-6141 for a free written estimate.

Windows in Gambrills — Common Questions

How much does window replacement cost in Gambrills, MD?

Most Gambrills window jobs run about $650 to $1,500 per window installed, or roughly $10,000 to $30,000 for a whole-home replacement. Cost depends on size, style, glass package, and whether an opening needs full-frame work. The larger colonials with many openings sit toward the top. We measure every opening and put a line-itemed number in writing before scheduling.

Why are the windows on my 1990s Gambrills colonial failing?

Age. The builder-grade windows on Gambrills' 1990s–2010s subdivisions are now at the point where the argon has bled out of the sealed units, the weatherstripping has hardened, and the earliest vinyl frames are fogging with failed seals. That leaks air and drives up your BGE bill. ENERGY STAR Low-E windows with argon fill fix it.

Insert or full-frame replacement — which do I need?

It depends on each opening, so we inspect them. If the frame and sill are sound, an insert replacement keeps your trim and interior finish. If there's rot or a failing original frame, full-frame replacement lets us flash and foam-seal the opening correctly instead of hiding a water problem behind new glass.

Will you handle the HOA architectural review in my Gambrills community?

Yes. Two Rivers, Walden, and most Gambrills communities run architectural review that can cover window style and grille pattern. We match the sightlines to your colonial's design and prepare and submit the board paperwork so the project is approved before we start.
