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!
Jessup's windows tell two stories. In the older sections of Maryland City, Savage, and Brockbridge, the original aluminum and early vinyl units on decades-old homes have lost their seals — the fog between the panes gives them away — and they bleed heat in January and let cool air escape through Maryland's humid summers. In the newer developments near Annapolis Junction and Dorsey, many of them home to Fort Meade and NSA families, the builder-grade double-hungs installed to hit a price point are already fifteen years old and failing early. Sitting in Howard County's 20794, it's a practical community where homeowners want lower BGE bills and windows that finally seal tight.
We replace them with ENERGY STAR-rated windows matched to how each home is built and how it faces. For most Jessup homes that means double-hung or casement units with Low-E glass and argon fill, installed as inserts where the existing frames are still sound or full-frame where there's rot or old air leaks to correct. On the sun-exposed elevations we spec the Low-E coating that cuts solar heat gain so upstairs rooms stop baking in July, and on the older homes we match sightlines and grille patterns so the new windows suit the house. Every opening is flashed and foam-sealed, because a window is only as good as the air-and-water seal around it — and that seal is exactly where cheap installs leak and BGE bills climb.
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 Howard County permits, and in the HOA developments near Dorsey we coordinate on approved window styles and grille patterns. For the military families moving on a PCS timeline, we give a firm written scope and per-window price before scheduling and keep the job on schedule.
We measure every opening first and note which frames can take an insert versus a full-frame replacement, in writing, so there are no surprises on install day. Apper Construction has been family-owned since 2016 and installs with its own local crew on every Jessup job, so the same team that measures your Maryland City or Savage windows is the one accountable to the workmanship warranty we hand you. As a licensed window contractor in Jessup, we handle full-frame window installation and replacement.
Most Jessup window projects run $650–$1,400 per window installed for standard double-hung or casement units, with bay, bow, and specialty shapes higher. Whole-home replacements of 10–20 windows typically land between $9,000 and $28,000 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 Jessup — Common Questions
How much does window replacement cost in Jessup, MD?
Most standard double-hung or casement windows run $650 to $1,400 each installed in Jessup. Bay, bow, and specialty shapes cost more. A whole-home replacement of 10–20 windows usually lands between $9,000 and $28,000 depending on size, glass package, and full-frame versus insert install.
Will new windows actually lower my BGE bill?
On older Jessup homes with failed aluminum or early vinyl windows, yes — noticeably. And on the newer homes near Dorsey, ENERGY STAR Low-E glass with argon fill outperforms the builder-grade units that came stock, cutting the heat loss and solar gain so your HVAC runs less year-round.
Full-frame or insert replacement — which do I need?
It depends on the existing frame. If the frame and sill are still sound, an insert (pocket) replacement is faster and less invasive. If there's rot or you want to correct old air leaks — common on the older Maryland City and Savage homes — full-frame is the right call. We inspect and note it per opening in writing.
Can you work around a military moving timeline?
Yes. Many Jessup homeowners are Fort Meade and NSA families on PCS timelines. We give a firm written, per-window scope and price before scheduling, use our own local crew so the job doesn't wait on subcontractors, and keep it on schedule. We also pull Howard County permits and handle HOA style approvals.
