Most Damascus homeowners aren’t renovating to impress a buyer. They’re renovating because they’ve been in Sweepstakes or Kings Valley for 20 years, they’re staying, and the original bathroom from 1983 has finally reached its limit. That’s a different kind of project and it deserves a different approach.
When you’re not going anywhere, the bathroom has to actually function for the long haul. That means proper waterproofing, not just fresh tile on top of an aging substrate. It means an exhaust fan sized for the room, not the cheapest unit that fits the hole. Damascus summers are humid genuinely, persistently humid and a bathroom that isn’t built to handle that will show you the damage within a few years.
Mold behind tile, soft spots in the floor, grout that starts cracking before the warranty conversation even comes up. These aren’t hypotheticals in northern Montgomery County; they’re what happens when waterproofing gets skipped to save a day or two.
What you get on the other side of a well-executed bathroom renovation is simple: a room that works every morning, holds up through every summer, and doesn’t become a problem you have to revisit. No callbacks, no remediation, no ripping out tile that was set on the wrong substrate. Just a bathroom that was built right the first time and stays that way.
Optima Design Group was founded in 1973 which means we were remodeling bathrooms in Montgomery County before most of Damascus’s current subdivisions were even platted. That’s not a trivia point. It means we’ve worked in the housing stock you’re living in, we know the plumbing configurations of that era, and we’re not caught off guard by what a 1978 bathroom looks like when you open it up.
We hold an active Maryland MHIC License (#28145) and carry general liability insurance and workers’ compensation coverage, which matters when someone is doing real construction work in your home. We’re also licensed in DC and Virginia so if your situation ever crosses a jurisdictional line, there’s no gap in coverage.
Damascus homeowners tend to be thorough when they vet a contractor. That’s the right instinct. We’re licensed, bonded, insured, and we’ve been doing this work in northern Montgomery County long enough that our reputation has had time to mean something.
It starts with a conversation about what you have and what you want. We look at the existing layout, the plumbing configuration, the condition of the substrate all the things that determine what the project actually involves before a single tile gets pulled.
If you’re on a private septic system, which applies to a number of Damascus properties on larger lots, we flag that early. Any plumbing changes that affect drainage can trigger a Montgomery County dye test requirement, and you want to know that before the project starts, not mid-demolition.
From there, we handle the permitting. Montgomery County’s Department of Permitting Services covers all of Damascus, and any bathroom work involving plumbing or electrical requires a permit. We manage that process the application, the inspections, the sign-off so you’re not chasing paperwork while trying to get ready for work in the morning.
The actual construction follows a clear sequence: demolition, waterproofing, substrate, tile, fixtures, finish work. We don’t skip the waterproofing layer to save a day. That’s the step that determines whether your bathroom holds up for five years or thirty. When we’re done, the space is clean, the work is inspected, and you’re not left wondering if something was done right.

The bathroom work we do in Damascus covers the full range full gut renovations, walk-in shower installations, tub-to-shower conversions, floor and wall tiling, cabinet replacement, and repainting. If your home was built in the 1970s or 1980s, there’s a good chance the bathroom has a single-piece fiberglass insert that’s been there since the beginning.
Replacing that with a properly built, tiled walk-in shower custom bench, built-in shelving, frameless glass if that’s the direction you want to go changes how the room feels and functions entirely. For smaller bathrooms, which are common in Damascus’s older subdivisions, a well-designed walk-in shower with frameless glass actually opens the room up rather than closing it in. It’s one of the most effective layout moves for compact spaces, and we’ve done it enough times in Montgomery County homes to know what works in a real bathroom footprint versus what looks good in a showroom.
Everything stays in-house. Tile, painting, carpentry, installation one team, one point of contact, one schedule. For Damascus homeowners who leave early and get home late, that matters. You’re not coordinating between three different contractors who’ve never met. You call us, and we handle it.
Yes, if the work involves plumbing, electrical, or structural changes. Damascus is an unincorporated community in Montgomery County, MD, which means all permits are issued through the Montgomery County Department of Permitting Services located at 255 Rockville Pike in Rockville. Cosmetic work like repainting, replacing a faucet, or swapping out countertops generally doesn’t require a permit.
But if you’re moving a drain, adding a circuit, or reconfiguring the layout, a permit is required. Skipping that step isn’t worth it. Unpermitted work can create real problems when you refinance or sell, and Montgomery County inspectors do issue Stop-Work Orders for construction discovered without permits.
We handle the permit application and coordinate the inspections as part of the project you don’t have to manage that process yourself. It’s worth noting that Montgomery County is implementing a 15% permit fee increase in the 2027 fiscal year, so if you’re weighing timing, that’s a factor to consider.
For a smaller bathroom the kind common in Damascus homes built in the 1970s and 1980s active construction typically runs two to three weeks. When you factor in permit processing and the planning phase upfront, the full timeline from first conversation to finished bathroom is usually four to six weeks.
Larger or more complex projects, like a full master bathroom renovation or one that involves significant plumbing relocation, can run longer. The timeline is also affected by material lead times. If you’re selecting custom tile or specialty fixtures, those need to be ordered and on-site before certain phases of work can proceed.
We walk through that sequencing at the start of the project so there are no surprises mid-construction. For Damascus homeowners with demanding commutes, we’re clear about what days require access and what days the crew is working independently you shouldn’t have to rearrange your schedule around us more than necessary.
It can, depending on what the remodel involves. If you’re doing cosmetic work retiling, replacing fixtures, repainting a septic system isn’t a factor. But if the project involves adding a bathroom, relocating drains, or making changes that affect water usage or drainage flow, Montgomery County may require a dye test and site verification by a licensed installer before the work proceeds.
This is something we flag at the very beginning of the project for any Damascus property on a private septic system, which applies to a number of homes on larger lots outside the denser Town Center areas. An inexperienced contractor who doesn’t know the local requirements might not raise this at all, leaving you to discover the issue mid-project which is a significantly worse situation.
We know the Montgomery County requirements and coordinate accordingly so there are no stops or surprises once construction is underway.
A mid-range walk-in shower installation porcelain tile, frameless glass, standard plumbing configuration typically runs in the range of $8,000 to $10,000 based on current market data. The full range for walk-in shower installations runs from roughly $6,000 on the lower end to $12,000 and up for more involved configurations, custom features, or projects that require significant plumbing relocation.
For a full bathroom renovation in a Damascus home, the national median spend in 2025 is around $15,000, though the final number depends on the scope of work, the condition of what’s behind the walls when demolition starts, and the materials you select. Homes built in the 1970s and 1980s sometimes have aging subfloor or plumbing that needs to be addressed as part of the project we identify those conditions early and walk you through what they mean for the scope and budget before any work begins.
We don’t publish fixed prices on the website because every bathroom is different, but we do provide detailed written estimates so you know exactly what you’re agreeing to before anything starts.
Damascus sits in northern Montgomery County with warm, humid summers average July highs around 85°F and sustained high humidity from June through August. That climate is hard on bathrooms that aren’t built to handle moisture properly. Undersized exhaust fans, inadequate waterproofing behind tile, and grout that wasn’t sealed correctly all become visible problems faster in a humid environment than they would in a drier climate.
Research on bathroom renovation failures consistently points to waterproofing as the most common and most expensive issue repairs for waterproofing failures run from $2,000 to $12,000, and they’re the leading cause of post-renovation insurance claims. In Damascus’s climate, that risk isn’t theoretical.
We use professional-grade waterproofing membranes not consumer-grade products and we size exhaust ventilation for the actual room, not just the minimum code requirement. That’s not an upsell. It’s what the work requires to hold up in this environment for the long term.
Damascus is in Montgomery County, MD, which means any contractor doing home improvement work here needs an active Maryland Home Improvement Commission (MHIC) license. That’s a state-level requirement, and it’s verifiable you can look up any contractor’s MHIC number through the Maryland MHIC database online. Optima Design Group holds MHIC License #28145, which you can confirm independently.
Beyond the license itself, look for general liability insurance and workers’ compensation coverage. Liability insurance protects your home if something is damaged during construction. Workers’ compensation protects you from being held liable if someone is injured on your property while working. Ask for both before signing anything.
A contractor who hesitates to provide proof of either is a contractor worth walking away from. In a community like Damascus, where most homeowners have been in their homes for years and have real equity on the line, the licensing and insurance verification step is worth the five minutes it takes. We provide all of that documentation upfront no chasing required.
