Trusted Sunroom Builders Nationwide
A sunroom should add a bright, usable room to your home, not a hot box in July and an icebox in January. Most of the sunrooms we get called about were built without a real plan for heat, glass, or drainage, and the owners stopped using them within two years. Lodgewick ADU Builders has been building additions the right way since 2010 as part of the Kingswell family of home-service companies. If you also want to compare a full room addition contractor build, we can price both side by side.
A sunroom is a glass-walled room attached to your house, built to bring in natural light and give you a space you can use for most or all of the year. It can be a breakfast room, a home office, a plant room, or a quiet place to read. Russ Delmar leads our team, and every project runs under The Kingswell Guarantee: a written price before work begins, a defined arrival window, a clean job site, and a written guarantee on every build. Call (254) 602-5618 and a live person answers, 24/7.

Three-Season Sunrooms
A three-season sunroom is a glass room built for spring, summer, and fall. It usually has single-pane or basic double-pane windows, no insulation in the walls, and no connection to your home heating and cooling. Homeowners pick this style when they want a lower-cost way to enjoy the yard without a full addition. Lodgewick ADU Builders builds three-season rooms with proper framing, flashing, and drainage so they last.
What You Give Up and What You Save
The tradeoff is simple. Without insulation and conditioned air, the room gets cold in deep winter and warm on bright afternoons. In return, the price is far lower than a four-season room, often $20,000 to $50,000 for a standard size. We tell you plainly what you will and will not be able to do in the room so there are no surprises after the glass goes in.
Many owners add a small heater or a ceiling fan later. We rough in the electrical for those during the build, which costs a fraction of opening walls afterward.
Screen Rooms and Convertible Options
Some homeowners start with a screened porch and convert it to glass. We build the frame and roof so that upgrade is possible later without tearing anything out. That is a quiet way to spread the cost over a few years.
Four-Season Sunrooms
A four-season sunroom is a fully insulated, climate-controlled room that works like any other room in the house. It has insulated walls and roof, energy-rated glass, and heating and cooling tied into your system or served by its own mini-split. Homeowners choose this style when they want a true year-round living space, home office, or hobby room. Lodgewick ADU Builders treats a four-season sunroom as a real addition, built to the same code as the rest of your home.
Insulation, Heating, and Cooling
Glass loses and gains heat faster than a wall, so the system has to be sized for the room you actually have. We calculate the load before we choose equipment. A ductless mini-split is the most common answer because it heats and cools the room without taxing your main furnace or air conditioner.
The written estimate lists the equipment, the electrical work, and the insulation values by line. You see what is behind the walls before they are closed up.
Matching the Room to Your Home
The best sunrooms look like they were always part of the house. We match roof pitch, siding, trim, and flooring height so the room reads as part of the original design. A good transition at the door, with no step and no gap, makes a big difference in how the space feels.
Foundations and Structure
The foundation and frame decide whether a sunroom stays square and dry for decades or starts leaking at the wall in a few seasons. A sunroom carries glass, which is heavy and unforgiving, so the structure has to be right. Lodgewick ADU Builders checks the soil, the frost depth, and the condition of your existing house wall before we price the job.
Slab, Piers, or Existing Deck
Most sunrooms sit on a poured slab or on concrete piers. Using an old deck as the base is tempting, but many decks were never built to carry a roof and glass walls. We inspect the footings, the ledger, and the framing, and if the deck is not up to it, we say so and show you the fix in writing.
A new slab on a typical 12 by 16 room is a modest part of the total cost. Skipping it on a weak base is where owners end up paying twice.
Attaching to the House
The joint where the new room meets your existing wall is where most leaks start. We flash it in layers, lap the water barrier correctly, and keep the roof tie-in clear of valleys that collect debris. This is slow, careful work and it is the part you will never see, which is exactly why we do it the same on every job.
Glass, Roof, and Energy Performance
Glass choice sets the comfort, the energy bill, and how much furniture fades in the sun. A sunroom with the wrong glass can be unusable by noon. Lodgewick ADU Builders explains the options in plain terms and matches them to your orientation, your region, and your budget.
Low-E and Insulated Glass
Low-E coatings reflect heat while letting light through. On a south or west wall they can cut the heat load noticeably. Double-pane insulated units with argon fill are the standard for four-season rooms. For three-season rooms, we still recommend tempered or laminated glass for safety.
Roof Styles
You can choose a solid insulated roof, a glass roof, or a mix. A solid roof with a few skylights keeps the room cooler and quieter in rain. A full glass roof gives the open feeling many people want, but it needs shading and good ventilation. We show you both options with the written price for each, so the choice is based on real numbers.
Ceiling fans, operable windows, and a vented ridge all help a sunroom shed heat. We plan them in at the start.
Permits and Code Requirements
A sunroom is an addition, and in almost every jurisdiction it needs a building permit. Setbacks, lot coverage, and energy code rules vary widely, and building without approval can lead to fines or an order to remove the work. We pull the permits and schedule the inspections as part of the written scope.
Setbacks and Lot Coverage
Your lot has limits on how close you can build to a property line and how much of the lot can be covered. We check those before we draw anything, so the design is one the building department will approve. If the room cannot go where you pictured it, we tell you early and show you the closest option that works.
Energy and Safety Rules
Four-season rooms must meet the local energy code, which sets glass ratings and insulation levels. Any glass near a door or low to the floor must be safety glazing. Rooms with fuel-burning appliances need proper venting. We handle each of these items so your final inspection passes the first time.
Sunroom or Room Addition?
Many homeowners are not sure whether a sunroom or a standard addition fits their goals. A sunroom is lighter, faster to build, and usually costs less per square foot. A standard addition has solid walls, which gives you more privacy, easier furniture placement, and better sound control. If you need a bedroom or a larger multi-use space, see our second story addition contractor page or our ADU construction service for a fully independent unit.
We are not set up to push you toward the bigger job. If a sunroom is the right size of project, we say so, and the written estimate shows it. For homeowners weighing a few paths, we price each one so you can compare real numbers. You can also start from our home page to see everything we build.
Signs You Need a Pro Right Now
- An existing sunroom or enclosed porch leaks at the wall or roof joint. Water behind the siding rots framing quietly. We trace the source, repair the damage, and reflash the joint properly.
- Foggy glass between the panes. That means the seal has failed and the unit no longer insulates. We replace failed units and check the frame for moisture while the glass is out.
- The room is unusable most of the year. If it is too hot or too cold to sit in, the glass, ventilation, or heating was never sized right. We can upgrade the room instead of rebuilding it.
- A previous contractor walked off the job. We see this too often. We assess what was done correctly, what needs redoing, and give you a written price to finish the project.
- You have a quote that feels too low or too vague. If it does not list the slab, permits, electrical, glass, and finishes, it is not a real price. We show every line item before you sign anything.
Our Process, Step by Step
- 1
Phone consultation. Call (254) 602-5618 and a live person answers. We talk through how you want to use the room, your budget range, and the basics of your home. If it makes sense to move forward, we schedule a site visit.
- 2
On-site assessment. We walk the property and measure the wall, the grade, the sun exposure, and the utility locations. We take photos and notes that drive the design and the written price.
- 3
Written estimate and scope. You get a line-item written price covering foundation, structure, glass, roof, electrical, climate control, permits, and the 365-Day Done Right Promise. No vague allowances. No price changes at the door.
- 4
Design, permits, and ordering. We finalize the plans, submit for permits, and order the glass and long-lead materials. You get a schedule with defined arrival windows, and we hit them or call ahead with a new time.
- 5
Construction and final walkthrough. Our uniformed crew builds to the plan, keeps the site clean daily, and walks you through the finished room before we call it done. The written guarantee is in your hands at completion, not promised later.
How Much Does Sunroom Builders Cost?
Sunroom costs depend on the style and the site, but honest national ranges help you plan before you sign anything. A three-season sunroom typically runs $20,000 to $50,000. A four-season sunroom with insulated walls, quality glass, and climate control usually lands between $50,000 and $120,000. Large custom rooms with a glass roof, premium finishes, or a difficult foundation can go higher. The written price you get from Lodgewick ADU Builders shows every line item, so there is no mystery about where the money goes.
What moves the number: room size, foundation type, glass quality, roof style, how much electrical and HVAC work is needed, and how much of your existing wall must be modified. The way to avoid overpaying is to get a fixed written price with no allowances for vague categories. The way to avoid underpaying and getting burned is to check that the low bid includes permits, the foundation, and a real warranty. Our free estimate includes the full written scope, the schedule, and the guarantee in writing.

Frequently Asked Questions About Sunroom Builders
Sunroom builders design, permit, and construct glass-walled rooms attached to your home. That covers the foundation, framing, roof, glass, electrical, and any heating or cooling. Lodgewick ADU Builders has built additions since 2010 and handles the whole project under one written contract, from the first site visit to the final inspection.
A three-season room has no insulation or climate control and is comfortable in spring, summer, and fall. A four-season room is fully insulated, uses energy-rated glass, and has heating and cooling, so you can use it all year. The four-season option costs more but works like any other room in the house.
A three-season sunroom typically runs $20,000 to $50,000. A four-season sunroom usually lands between $50,000 and $120,000. Size, foundation, glass, and climate control move the number. You get an exact written price before any work begins, with every line item shown. Call (254) 602-5618 for a free estimate.
In almost every area, yes. A sunroom counts as an addition, so it needs a building permit and inspections, and it must follow local setback and energy rules. We pull all permits and schedule all inspections as part of the written scope, so the room is legal from day one.
Most sunrooms take four to ten weeks of construction once permits and materials are in hand, depending on size and style. Permitting and custom glass lead times can add several weeks before work starts. Your written schedule shows the arrival windows and milestone dates before the first day on site.
Every Lodgewick ADU Builders project includes the 365-Day Done Right Promise in writing. If the work is not right within a year of completion, we come back and make it right at no charge. That covers our workmanship and the materials we installed, and it is printed in the contract before construction begins.
