Leisure World was built starting in 1965, with most of its units going up through the 1970s and 1980s. That means a lot of windows in this community are pushing 40, 50, even 60 years old. Original aluminum-frame single-pane windows from that era have almost no insulating value by today’s standards. Even early double-pane units from the 1980s frequently develop failed seals that foggy, cloudy look between the panes that tells you the insulating gas is gone and you’re essentially back to single-pane performance. You can’t repair that. It has to be replaced.
The U.S. Department of Energy estimates that windows account for 25 to 30 percent of a home’s heating and cooling energy use. For a Leisure World resident who’s home during the day, every day, that’s not a statistic it’s what you feel every winter morning near a drafty window and every summer afternoon when the AC can’t keep up. Replacing old windows with ENERGY STAR certified double-pane units can reduce your utility bills by an average of $42.50 per month. That’s over $500 a year back in your pocket, just from better glass.
There’s also a federal tax credit available right now. Through 2032, the IRS offers a 30 percent credit on qualifying window materials up to $600 per year under Section 25C of the Inflation Reduction Act. If your windows qualify, that’s real money returned at tax time on top of the monthly savings. For anyone managing a fixed income, that combination matters.
We’ve been working in the DC metro area since 1973. That’s not a marketing line it means Gordon Franks, our founder and owner, has been doing this work in Montgomery County longer than many Leisure World residents have lived here. When you reach out, you’re talking to him directly. Not a salesperson. Not a scheduler. The person who will write your contract and make sure the job gets done right.
We hold an active Maryland Home Improvement Commission license (MHIC #28145), which is required for any contractor pulling a building permit in Montgomery County. Optima Design Group is also fully licensed in Washington, D.C. and Virginia, and we carry full general liability and workers’ compensation insurance. In a community like Leisure World where exterior modifications require mutual board approval and the work happens in close proximity to neighbors that kind of documented, verifiable credentialing isn’t optional. It’s the baseline.
We’ve earned 300-plus recommendations on Washington D.C. Consumers’ Checkbook, a subscription-based consumer research service that doesn’t sell placements. That’s the kind of track record you can actually verify.
The first step is a free in-home estimate. Gordon comes out, looks at your existing windows, and gives you a clear picture of what replacement involves what type of windows make sense for your unit, what the scope of work looks like, and what documentation you’ll need if your mutual requires board approval before exterior work can begin. If you’re in a mutual like Mutual 14, which explicitly lists window replacement as a modification requiring board sign-off, that approval step happens before any scheduling. We can help you understand what the board typically needs and how to document the project correctly.
Once approvals are in place and materials are ordered, installation moves quickly. For most insert replacements where the new window fits into the existing frame opening without structural changes our professional crew can complete eight to twelve windows in a single day. You’re home for the whole thing, which is why punctuality and cleanup matter. We work clean, protect your floors and furniture, and leave the space the way we found it.
Montgomery County adopted updated building codes in December 2024, including new energy efficiency requirements for replacement windows in Climate Zone 4A. Any windows we specify for your project will meet those standards. If your replacement involves structural changes to the opening, we handle the Montgomery County permit process as part of the job including the MHIC license documentation the county requires.

Not every window in Leisure World faces the same conditions. A unit in The Overlook with south- or west-facing glass overlooking the golf course gets full afternoon sun with no shade buffer. That’s a very different thermal challenge than a ground-floor garden condo facing an interior courtyard. The window that’s right for your unit depends on its orientation, its exposure, and what you’re actually trying to fix whether that’s heat loss in winter, solar heat gain in summer, road noise from Georgia Avenue, or failed seals that have been fogging up for years.
We handle vinyl window replacement, double hung window installation, and energy efficient window upgrades throughout Leisure World and the broader Silver Spring area. Vinyl is the most common choice it holds up well in Montgomery County’s mixed climate, requires virtually no maintenance, and consistently qualifies for ENERGY STAR certification. For units near the perimeter along Georgia Avenue or Norbeck Road, double-pane glass with a laminated acoustic interlayer can make a real difference in day-to-day noise levels, which matters more when you’re home during the day.
Every window we specify for a Leisure World project carries NFRC performance ratings the independent certification that lets you compare actual U-factor and solar heat gain numbers across brands, not just marketing claims. That documentation also supports your federal tax credit filing and gives your mutual board the technical specs they may request as part of the approval process.
In most cases, yes. Leisure World’s individual mutuals govern exterior modifications, and window replacement typically falls under that category. Mutual 14’s published renovation rules, for example, explicitly list window and door replacement as modifications requiring board approval, and the mutual retains authority over exterior styles and colors. Other mutuals have similar requirements through their Architectural and Environmental Control Committees.
This doesn’t mean the process is complicated it means you need to start there before scheduling any work. Your mutual’s bylaws are available through HomeWiseDocs.com, and most boards have a straightforward review process. What helps is working with a contractor who already understands what the board typically needs: product specifications, NFRC ratings, proposed colors, and a description of the scope. We’ve worked in managed communities throughout Montgomery County and can help you pull together the right documentation so the approval process doesn’t slow down the project.
It depends on the scope of work. A standard insert replacement where the new window fits into the existing frame opening without changing the rough opening size generally does not require a building permit in Montgomery County. This is the most common type of replacement in Leisure World’s condominiums and townhomes, and it’s the reason most projects can be completed in a single day.
If the work involves structural changes to the window opening enlarging it, adding a new window where there wasn’t one, or doing a full-frame replacement that alters the rough opening then a Montgomery County Department of Permitting Services permit is required. Any contractor pulling that permit must hold an active Maryland Home Improvement Commission (MHIC) license. We hold MHIC #28145, which means the permit process is handled correctly from the start. Montgomery County also offers a Fast Track review program that can turn around eligible permits in three to five business days, so a permit requirement doesn’t necessarily mean a long delay.
There are a few things worth looking at. If you see fog or condensation between the panes of glass that hazy, cloudy film that doesn’t wipe off the seal has failed. The insulating gas fill has escaped, and the window is performing at roughly single-pane efficiency. That can’t be repaired. The glass unit needs to be replaced, and in most cases it makes more sense to replace the full window rather than just the glass.
Other clear signs: the sash is difficult to open or close, there’s visible rot or corrosion on the frame, you can feel a noticeable draft near the window on a cold day, or the window is a single-pane aluminum unit from original construction. Given that Leisure World’s housing was built primarily in the 1960s and 1970s, a significant number of units still have windows from that era or first-generation replacements from the 1980s and early 1990s that are now approaching or past the end of their useful life. A free in-home estimate gives you a clear answer without any obligation to move forward.
Montgomery County sits in IECC Climate Zone 4A, which is classified as mixed-humid. That means your windows need to perform in both directions holding heat in during cold winters and blocking solar heat gain during hot, humid summers. The county’s updated building codes, adopted in December 2024, set specific performance thresholds for replacement windows: a U-factor of 0.30 or lower and a Solar Heat Gain Coefficient of 0.40 or lower for most residential applications.
For most Leisure World units, a double-pane vinyl window with Low-E glass and an argon gas fill meets those requirements comfortably and qualifies for ENERGY STAR certification. Low-E coating reflects infrared heat back into the room in winter and blocks it from entering in summer which is particularly useful for south- and west-facing units in Leisure World that overlook the golf course and get extended afternoon sun exposure. Triple-pane glass is available for units with extreme exposure or specific acoustic needs, though double-pane with the right glass package handles the vast majority of situations well.
Yes, and the numbers are specific enough to be worth looking at. The U.S. Department of Energy estimates that windows account for 25 to 30 percent of a home’s heating and cooling energy use. ENERGY STAR certified replacement windows save an average of $42.50 per month compared to older single-pane or failed-seal double-pane windows based on a 2025 survey by This Old House across real homeowner projects.
For a Leisure World resident who’s home all day, that monthly figure is more meaningful than it might be for someone who’s out of the house from 7am to 7pm. You’re running the heat or AC during the hours when the sun hits hardest and the cold is most persistent. The savings add up faster. On top of the monthly reduction, qualifying ENERGY STAR windows currently make you eligible for a federal tax credit of up to $600 per year on material costs through 2032. Between the two, a window replacement project can return over $1,000 in year one alone for many households.
A few things set us apart. First, we’re a Montgomery County contractor headquartered in Bethesda, licensed under MHIC #28145, and familiar with the permit process at Montgomery County’s Department of Permitting Services. That’s not the case for every window company that shows up in a search result for Silver Spring or the 20906 ZIP code. Some are lead-generation services that refer your project out. Some use subcontractors for installation. Knowing who is actually doing the work and whether they’re properly licensed for the county you’re in matters.
Second, we’re a general contractor, not a window-only specialist. That means if your replacement project uncovers trim damage, requires drywall repair, or needs paint touch-up around the new frames, it gets handled in the same project by the same crew. You’re not coordinating two or three separate contractors. Third, Gordon Franks has been doing this work in the DC metro area since 1973. Leisure World itself was founded in 1965. Our history in this market nearly spans the community’s entire existence and that kind of longevity in one market is hard to fake.
