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!
Severna Park has some of the largest, most exposed homes in Anne Arundel County, and their windows work hard for it. The waterfront properties on the Magothy and Severn take wind and salt air off the water, and the 1970s–1990s colonials through Chartwell, Berrywood, and Shipley's Choice are hitting the age where the original wood and early vinyl windows have lost their seals. You can see the fog between the panes, feel the drafts in January, and watch the BGE bill climb every summer as the afternoon sun pours through single-pane and failed double-pane glass on the big west-facing elevations.
We replace them with ENERGY STAR-rated windows matched to how the house is built and how it faces. For most Severna Park homes that means double-hung or casement units with Low-E glass and argon fill, in a full-frame or insert installation depending on whether the existing frames are still sound. On the waterfront and west-facing elevations that take the sun and wind, we spec the Low-E coating that cuts solar heat gain and the impact-rated options where exposure calls for it. Every opening is flashed and foam-sealed so the new window performs the way the label promises — a window is only as good as the water-and-air seal around it, and that is where cheap installs fail first.
Every project is installed by our own local crew, and backed by a written workmanship warranty separate from the manufacturer's glass warranty. We pull Anne Arundel County permits, and for the communities with architectural review we match sightlines and grille patterns where it matters. Before we quote, we measure every opening and note which frames can take an insert versus a full-frame replacement, and we put that in writing so there are no surprises on install day. As a licensed window contractor in Severna Park, we handle full-frame window installation and replacement.
Most Severna Park window projects run $650–$1,500 per window installed for standard double-hung or casement units, with bay, bow, and specialty shapes higher. Whole-home replacements of 12–25 windows on the larger homes here typically land between $11,000 and $34,000 depending on size, glass package, and full-frame versus insert. You get a written, per-window estimate before scheduling. Call 410-508-6141.
Windows in Severna Park — Common Questions
How much does window replacement cost in Severna Park, MD?
Most standard double-hung or casement windows run $650 to $1,500 each installed in Severna Park. Bay, bow, and specialty shapes cost more. A whole-home replacement of 12–25 windows on the larger homes here usually lands between $11,000 and $34,000 depending on size, glass package, and install type.
Full-frame or insert replacement — which do I need?
It depends on the existing frame. If the frame and sill are sound, an insert replacement is faster and less invasive. If there is rot — common on older waterfront homes — or you want to correct air leaks, full-frame replacement is the right call. We inspect and note it per opening in writing before you decide.
What glass should I choose for a waterfront home?
For Severna Park waterfront and west-facing homes, Low-E glass with argon fill cuts the solar heat gain and heat loss those big exposed elevations let through. Where exposure to storms off the water is a concern, we can spec impact-rated units. We match the package to each elevation.
Will new windows lower my BGE bill?
On the 1970s–1990s Severna Park homes with failed wood or early vinyl windows, yes — noticeably. ENERGY STAR Low-E glass stops the heat loss and solar gain those old units let through, especially on the large west- and south-facing elevations common here.
