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!
Hanover's homes are young by Maryland standards — the townhomes and single-family houses of Arundel Preserve, the Reserve at Arundel Preserve, Oxford Square, Two Rivers, and Parkside mostly went up in the 2000s and 2010s near Arundel Mills, where the 21076 ZIP straddles Anne Arundel and Howard counties. That youth fools people into thinking the windows are fine, but the builder-grade double-hungs installed during that boom were the cheapest units that met code, and fifteen-plus years of Maryland summers and winters have taken their toll: seals are starting to fail, you'll spot fog between the panes, sashes stick, and the thin glass packages let heat pour out of end units and top floors.
We replace them with ENERGY STAR-rated windows chosen for how each home is built and how it faces. For most Hanover townhomes and single-family homes that means double-hung or casement units with Low-E glass and argon fill, installed as inserts where the builder's frames are still square and sound, or full-frame where they aren't. On the tall, sun-exposed elevations common in these newer developments, the right Low-E coating cuts solar heat gain so upstairs bedrooms stop overheating in July. Every opening is flashed and foam-sealed — the same detail rushed builder crews often shortcut — so the new window actually delivers the efficiency on its label and your BGE bill reflects it.
Every project is installed by our own local crew, and backed by a written workmanship warranty separate from the manufacturer's glass warranty. Because Hanover sits across the county line, we pull permits from whichever jurisdiction your address falls under, and we coordinate with your HOA on approved window styles and grille patterns in the planned communities so your replacement clears review the first time. Before we quote, we measure every opening and note which frames can take an insert versus a full-frame replacement, then put that 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 Hanover job, so the crew replacing the windows in your Arundel Preserve or Oxford Square home is accountable to the same warranty we hand you — not a rotating cast of subcontractors. As a licensed window contractor in Hanover, we handle full-frame window installation and replacement.
Most Hanover 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 Hanover — Common Questions
How much does window replacement cost in Hanover, MD?
Most standard double-hung or casement windows run $650 to $1,400 each installed in Hanover. 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.
My house is only 15 years old — do the windows really need replacing?
Often, yes. The builder-grade double-hungs installed during Hanover's 2000s–2010s boom were the cheapest units that met code. After fifteen-plus Maryland seasons the seals fail, you see fog between the panes, and the thin glass lets heat escape — especially in end units and top floors.
Full-frame or insert replacement — which do I need?
It depends on the frame. Because Hanover homes are newer, many builder frames are still square and sound, which makes a faster insert (pocket) replacement possible. Where a frame is racked or leaking, full-frame is the right call. We inspect and note it per opening in writing before you decide.
Do you handle county permits and HOA approval in Hanover?
Yes. Hanover's 21076 straddles Anne Arundel and Howard counties, so we pull the permit from whichever applies, and we coordinate with your HOA in communities like Arundel Preserve and Oxford Square on approved window styles and grille patterns so your replacement clears review the first time.
