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!

Leandro and his company replaced the siding on my house. From the very beginning of the estimate to the completion of the job I was very pleased with it all. Leandro is kind, honest, polite and professional explaining every thing in detail with an itemized estimate. He and the crew were all prompt and efficient. I highly recommend!

Windows fail early in Pasadena because of where the town sits — a peninsula between the Magothy and Patapsco with salt-laden wind pushing moisture at every seal. The old aluminum windows in the winterized cottages around Riviera Beach and Green Haven, and the early vinyl units in the 1970s and '80s builds off Mountain Road, are the ones we're called to replace most. Owners see fogging and condensation trapped between the panes — the tell-tale sign of a blown seal — along with drafts, hard-to-open sashes stiff with corrosion, and rising BGE bills as the failed insulated glass stops holding conditioned air. On a waterfront elevation facing open water, a single-pane or blown-seal window is a genuine comfort and energy problem, not a cosmetic one. We replace with ENERGY STAR-rated windows — double-hung, casement, and bay units with Low-E coatings and argon fill that cut solar heat gain in summer and hold warmth in winter, which shows up directly on the power bill. The right install method depends on the wall. Where the existing frames and sills are sound, an insert replacement keeps the trim intact and goes in cleanly. Where salt and moisture have rotted the frame — common on older Pasadena shoreline homes — we go full-frame, remove down to the rough opening, inspect for hidden damage, and rebuild it properly. Every window is flashed and foam-sealed so wind-driven rain drains out instead of finding its way into the wall. For homes on the open water and the exposed points around Rock Creek and the Magothy, we offer impact-rated and sound-reducing glass packages that knock down both wind noise and storm exposure. Every job is installed by our own local crew and measured to the exact opening, because a window ordered a quarter-inch off is a window that leaks air for twenty years. A family-owned Anne Arundel contractor since 2016, we treat each Pasadena opening individually rather than working off a rough count, and we walk you through the difference between the glass packages before you commit. We give you a written, line-itemed estimate with the exact product, glass package, and install method spelled out, pull Anne Arundel County permits where required, and haul off every old sash and frame before we leave. As a licensed window contractor in Pasadena, we handle full-frame window installation and replacement.

Most Pasadena window projects run about $650–$1,500 per window installed, or roughly $9,000–$34,000 whole-home, depending on window type, glass package, insert vs. full-frame, and any frame rot. Impact and sound-reducing glass for waterfront elevations sit higher. You get a written, line-itemed estimate before anything is scheduled. Call 410-508-6141.

Windows in Pasadena — Common Questions

How much does window replacement cost in Pasadena, MD?

Most Pasadena window projects run about $650 to $1,500 per window installed, or roughly $9,000 to $34,000 for a whole home. Glass package, insert vs. full-frame, and any frame rot drive the number, and impact or sound-reducing glass for waterfront elevations sits higher. You get a line-itemed written estimate first.

My windows are foggy between the panes — why?

That fogging is a failed seal — the argon or air between the panes has leaked out and moisture got in, so the glass no longer insulates. It's common on the old aluminum and early vinyl windows in Pasadena's shoreline homes. Replacing with Low-E, argon-filled units restores the insulation and clears the view.

Insert or full-frame replacement?

It depends on the frame. If the existing frame and sill are sound, an insert keeps your trim and installs cleanly. On older Pasadena waterfront homes where salt and moisture have rotted the frame, we recommend full-frame so we can inspect the opening and rebuild it right.

Can you cut the wind noise from off the water?

Yes. For homes on open water around Rock Creek and the Magothy, we offer sound-reducing and impact-rated glass packages that lower both wind noise and storm exposure. We'll spec the right package for your elevation and put it in the written estimate.
