Four Seasons Room Contractor in Gaithersburg, MD
Elevate Remodels is a licensed and insured remodeling company based in Gaithersburg, Maryland, serving homeowners across Montgomery County. A four seasons room is one of the highest-value additions a homeowner can build because it adds true year-round living space, not just a seasonal bonus area. The difference between a sunroom that gets used three months a year and one that gets used every day of the year comes down to how it is built.
We build four seasons rooms the same way we build home additions: on a proper foundation, with fully insulated walls and roof, thermal-pane glass packages, and HVAC integration so the space is comfortable in January and August. Every project is managed from the first permit application through final finish work under one contract. You are not coordinating between a window company, a foundation contractor, and an HVAC subcontractor. We handle all of it.

How Your Four Seasons Room Project Works
Every four seasons room project at Elevate Remodels follows the same three-step process. You know what it costs before it starts, you know who is building it, and nothing gets added to the invoice without your written approval.
01
We come to your home, walk the space where the room will be built, and listen to how you want to use it. We assess the foundation requirements, HVAC options, and zoning conditions on your lot, and give you an honest read on what the project will cost and how long it will take. No obligation and no pressure.
02
We put together a written, itemized estimate covering every phase of the project: foundation, framing, roofing, glass package, HVAC, electrical, and interior finish. You see the full cost before approving anything. We also file the permit with Montgomery County and coordinate material lead times before construction begins.
03
Construction is managed by our team from foundation pour through final walkthrough. We coordinate every trade in the correct sequence, schedule all inspections, and keep you updated throughout the build. The project is not complete until you have walked the finished room and signed off.

Why Montgomery County Homeowners Choose Elevate Remodels for Their Four Seasons Room
A four seasons room is a long-term investment in your home, and the quality of the build determines whether it becomes one of your favorite rooms or a space you only use a few months a year. Here is what separates Elevate Remodels from kit installers and general exterior contractors.
Built as a Real Addition, Not a Kit
Most sunroom companies install prefabricated kit rooms with aluminum framing and limited insulation. Elevate Remodels builds four seasons rooms the same way we build home additions: stick-framed, fully insulated, on a permanent foundation, and tied into your home’s structure. The difference shows up in energy bills, comfort, and long-term performance.
Exterior Match to Your Existing Home
A four seasons room that looks like an afterthought hurts your home’s value and your enjoyment of the space. We match the exterior siding, roofline, trim, and window style of your existing home so the addition reads as part of the original structure, not a bolt-on. That integration matters at resale and it matters every time you pull into the driveway.
Proper HVAC Sizing
One of the most common mistakes in four seasons room construction is relying on the existing HVAC system without verifying it can handle the additional load. We calculate the heating and cooling load for the new space and recommend either an extension of your main system or a dedicated mini-split, whichever performs better. Getting this decision right is the difference between a comfortable year-round room and an expensive underperforming space.
Full Permit Management
A four seasons room is a full home addition in Montgomery County, which means it requires a building permit, zoning review, and multiple inspections. Elevate Remodels manages the entire permit process from application through final inspection. You do not chase the county, wait for callbacks, or track inspection windows. We handle it.
Frequently Asked Questions About Four Seasons Rooms in Montgomery County
Below are answers to the most common questions homeowners ask when planning a four seasons room or sunroom in Montgomery County, MD.
How much does a four seasons room cost in Gaithersburg, MD?
A four seasons room in Gaithersburg, MD typically costs $40,000 to $120,000 or more. Smaller insulated sunrooms start around $40,000, standard rooms between 200 and 350 square feet usually run $60,000 to $85,000, and larger rooms with premium glass and vaulted ceilings can exceed $120,000. The main cost drivers are square footage, foundation requirements, glass package, insulation, and HVAC approach. Elevate Remodels provides a detailed, itemized written estimate before any work begins. Call (301) 287-6134 to schedule a free in-home consultation.
What is the difference between a four seasons room and a three season room?
A four seasons room is fully insulated and climate-controlled for year-round use. A three season room is a lighter structure with limited insulation and no heating or cooling, meaning it is not comfortable during Maryland winters or peak summer. Four seasons rooms have proper foundations, insulated walls and roofs, thermal-pane windows, and HVAC integration. Three season rooms cost less upfront but cannot be used year-round. Elevate Remodels builds both and helps homeowners decide which fits their use case and budget.
Do I need a permit for a four seasons room in Montgomery County?
Yes. A four seasons room is considered a full home addition in Montgomery County and requires a building permit. Depending on your lot, the project may also require zoning review, setback confirmation, and impervious surface calculations. Elevate Remodels manages the full permit process from application through final inspection on every four seasons room project.
How long does a four seasons room take to build in Maryland?
A four seasons room in Maryland takes 8 to 14 weeks from permit approval to final completion. Smaller rooms can be completed closer to 8 weeks, while larger projects with complex foundations or custom glass packages run toward the 14-week end. Permit processing at Montgomery County can add 4 to 8 weeks before construction starts. Elevate Remodels provides a written project schedule as part of every estimate.
Can a four seasons room be tied into my existing HVAC system?
Yes, in most cases, but it depends on your existing system’s capacity and the size of the new room. If your HVAC can handle the additional load, we can extend supply and return ducts into the new space. If it cannot, a dedicated mini-split unit is typically the better solution because it provides independent temperature control and is more energy-efficient for a single-room addition. Elevate Remodels evaluates both options during the estimate and recommends the approach that will perform best for your home.

Yes. Elevate Remodels builds four seasons rooms and sunrooms throughout Montgomery County including Gaithersburg, Rockville, Bethesda, Germantown, Potomac, Chevy Chase, Olney, Kensington, Clarksburg, and Damascus.
