What Things Can Lower The Cost Of Garage Renovation?

Remodelling your garage can bring utility and value to your life and home. Garages are used for many things besides car storage. They can be storage areas for sports equipment and tools, including work areas and home gyms, and expand your living space if you do not use it as a car garage.

Garage remodels come in all shapes and sizes, from cosmetic makeovers to full conversions. This leads to a wide range of associated costs. The national average cost range for a garage remodel is between $7,000 and $15,000, with most homeowners spending around $11,000 on a full 2-car garage remodel with new cabinet storage and floor coating. 

This project’s lowest cost is around $3,000 for a cosmetic update with floor and wall paint and shelving. The high cost for this project is approximately $40,000 for a garage conversion that turns the garage into a bedroom and bathroom suite.

Garage Renovation Cost By Type

Like any renovation or remodelling project, there are levels of work that impact the outcome, including costs. In the case of a garage renovation, this can include a partial remodel, such as a cosmetic update, a full remodel, and garage conversion. Each has its set of costs and options to consider.

Partial Garage Remodel

The average cost of a partial garage remodels averages $500 to $5,000. Partial can take on many forms. It may focus on a specific thing, such as a new garage door, or be a cosmetic update of all surfaces like the floor and walls. 

Partial remodels make an older garage look better and can improve saleability. They do not change much in terms of structure. This is a good option if your garage looks tired and run down and you want to give it a facelift.

Full Garage Remodel

A full garage remodels costs between $7,000 and $15,000 on average. This is the most common type of garage remodels for those who intend to use their garages for car storage. It usually involves a high-quality floor coating, custom cabinets and storage units, finished walls, ceilings, and new garage doors. 

The idea is to make the garage a functional, attractive, and easy to care for space. You can use the garage for more than just car storage, but it does not lower your home’s value the way that removing the garage to turn it into a living space does. Full garage remodels take on many looks and styles that meet many needs and homes.

Garage Conversion Cost

Garage conversions have an average cost range of $20,000 to $75,000. Garage conversions make your car storage area into a living space. This could mean a home office or workroom, bedroom, mudroom, living room, or even a full apartment. Garage conversions have many pros and cons. 

They can expand your living space, particularly if you are not using it as a garage. They can be converted into nearly any room for any use, often for less than the cost of a full addition. However, if you plan on selling your home, converting your garage into a living space lowers your home’s value unless you add another garage to the property.

Cost To Remodel A Garage By Size

Full garage remodels some of the most common types of garage renovations. This is the project you want to undertake if you plan to use your garage as a garage but also need it to have more utility. Full remodels include new flooring, finished walls and ceiling, custom storage solutions, and a new door so that it looks good inside and out.

The cost of a full garage can be at least partially impacted by the space’s size. The larger the garage, the more room you have for storage or work areas. You also have more floor and wall space to cover and likely a larger garage door.

Partial Garage Remodel Cost By Type Of Project

A partial garage can take on many forms. It could be a simple cosmetic update, a new door, added storage, or other additions. While a full remodel may include several things simultaneously, a partial remodel focuses on one area. This means that partial remodels vary and have a wide range of costs.

Cost To Soundproof A Garage

The average cost of garage soundproofing is between $250 and $3,500. Soundproofing can be done on different levels. Soundproofing materials can be added to the floors, walls, ceiling, and garage door or areas adjacent to the house. 

Acoustic materials also come in many forms, from PET tiles that can be applied anywhere to foam insulation that improves sound quality. For this reason, costs vary greatly. When deciding to soundproof, consider where you need the most sound absorption and focus on those areas to get the most out of the project.

Remote Control Garage Door Cost

To have your garage door operate via remote control, the costs range from $300 to $940. It would help if you had a garage door opener that operates by remote control. There are several opener types and various remote systems. 

Each has costs for the opener and the installation. If you have an existing system that operates by remote control, you can purchase a replacement remote for $15 and $90, depending on the system. Remote controls do not work universally, so ensure that the remote and system are compatible.

Cost To Insulate A Garage

The average cost to insulate a garage is $400 and $1,000. Most garages are not insulated, so if you plan on using them for any reason other than car storage, insulating is generally a good idea. 

Your garage can be insulated in several ways, but ensuring you have insulation between the wall studs is a good first step. You can also choose to have an insulated door installed or to insulate beneath the exterior siding. 

The most common garage insulation is fibreglass batts, which are also the least expensive. You can use other materials, such as loose-fill, if your walls have already been finished.

Cost To Add Windows To A Garage Door

The cost to add windows to a garage door averages $400 to $1,000. Window panels can usually be added to a standard garage door more easily than windows can be added to the garage walls. 

They are typically priced and installed by the panel. Most people add at least 4-6 panels of glass to their doors to maximise the light, but you can add fewer or more. The price is influenced by the door material and window glass type. Adding double-pane or specialty glass increases costs.

Garage Door Remodel

The cost of a garage door remodels is between $500 and $2,000 on average. Garage doors come in many sizes and styles. They can also be made of different materials. You can choose the opening style, whether it is insulated, and how it operates. Garage doors are typically priced by size and material. This means that you can have a wide range of costs for the same project.

Cost To Finish A Garage

The average cost to finish a garage is between $500 and $2,000. Finishing a garage comes in many forms. In most cases, it gives the space for finished walls and ceilings since many garages are left with unfinished cavity walls. 

Finishing can also give the floor a different finish than the plain concrete that many new garages have. In some cases, it could include a finished wall system, similar to those in basements. You may choose to finish the entire garage at once, or you can do sections at a time, leading to cost variation.

Car Lift For A Home Garage Cost

The cost of adding a car lift to your garage averages $500 to $5,000. Car lifts are available in many forms. You can get a simple lift or something typically seen in a professional garage. If you frequently work on your car, having a high-quality lift in your garage can pay off in the long term. 

If you want a lift for occasional use, smaller models may be a better fit. Most lifts are designed to be stationary in the garage when not in use so that they can take up a lot of space.

Add A Ductless Air Conditioner To A Garage

The cost of adding a ductless air conditioner to a garage ranges from $700 to $3,000. Keep in mind that most garages are not insulated. 

If you plan on adding an AC, you may need a larger unit than normal, or you may find that you need to run it for longer periods to cool the garage. To remedy this, make sure you insulate before adding an AC. The air conditioner’s type and size vary based on your garage’s size and insulation.

Cost To Refinish A Garage Floor

The cost to refinish a garage floor averages $800 to $12,000. There are many ways to refinish a floor, from a simple coat of floor paint to repairing significant issues before giving it a full epoxy coat or a decorative stain. 

The costs are reliant on two factors - the finish level you want and the floor’s condition. Garage floors in poor condition cost much more to refinish than a garage floor in good shape with some surface staining. All types of garage floor refinishing have a range of options so that you can control your floor’s final appearance.

Exterior Makeover

Garage exterior makeovers cost between $1,200 and $6,000 on average. A makeover can be as simple as a fresh coat of paint or as complex as adding new siding and a new door. You may also choose to add new trim, lights, or decorative hardware. This leads to a wide range of projects and costs. Your garage should coordinate with your home’s exterior, even if the garage is detached.


The cost of garage storage averages $1,500 to $3,000. Garage storage comes in both premade and custom variations, with the readymade typically costing less than anything custom. Storage can be from simple pegboards and hooks to custom-made workbenches with cabinetry. 

Most people use a combination, and you likely need more than one thing like shelves or cabinets to make the space work for you. Consider the space’s layout and what you plan to store before starting. Maximising your storage increases the space’s utility.

Cost To Expand A Garage

The average cost to expand a garage ranges from $2,000 to $10,000. Garage expansions are major undertakings. They involve removing a wall and bumping the garage out or putting another story and roof on it. 

This can be costly, depending on how much you expand. Small bump-outs cost the least, while major expansions, which involve the garage’s framing and roofing, cost the most. It is important to consider the exterior’s appearance and how it coordinates with the garage and property when expanding.

Garage Floor Coating Price

The average cost of a garage floor coating is between $5,750 and $8,625. While there are many ways to seal or refinish a garage floor, a coating system is unique. This is a solid epoxy coat for the floor. It is the best option for garage floors, which tend to get used. 

A garage floor coating system protects your floor from future damage. It also helps transform its appearance for various looks, colours, and finishes. Garage floor coatings are often recommended as part of full and partial remodels.

Garage Conversion Cost By Type

When not using your garage for car storage, you can convert it into another space. This is true whether the garage is attached or detached and regardless of its size. Garage conversions have a wide range of costs. 

This is because garages may be “finished” or “unfinished” before the conversion, and many may not be insulated.

Conversions are often subject to local building codes and regulations. They require a permit, which costs $300 to ​$1,500. They can also have a range of costs, depending on what you convert them into.

Convert A Garage Into A Utility Room

The cost to convert your garage into a utility room is between $3,000 and $8,000 on average. Most utility rooms are not finished, so this project’s costs can be lower than other conversions. Most of your expenses come from plumbing and wiring to the area. 

Most garages are not already plumbed and do not have the necessary drains for things like water heaters. So, all utilities must be rerouted to this space. If you want to finish the laundry area, your costs are higher.

Garage To Gym Conversion Cost

The cost to convert a garage into a home gym averages $3,000 to $10,000. The costs are based on how comfortable you want the gym to be. If you need to add heating, cooling, or insulation, your costs are higher than if you only put down mats on the floor and add mirrors to the walls. 

Equipment costs also vary. Some home gym systems are very costly, while others are relatively inexpensive. Consider how you plan to use the space before converting it to make the most of your investment.

Convert A Garage Into A Mudroom

The average cost to convert a garage into a mudroom is between $7,000 and $12,000. Like the home gym, part of the costs come from how comfortable you want to be. Adding insulation, heating, or cooling increases your costs. 

In addition, the flooring type, cabinetry or storage, and garage finish impact prices. You must also decide if you want to remove the garage door and replace it with a standard entry door. This increases the project’s costs because it requires additional siding, exterior, and interior finish work.

Cost To Convert A Garage Into A Living Space

The cost to convert a garage into a living space ranges from $7,000 to $75,000. Garage living spaces can be interpreted in many ways. You can convert it to a playroom for kids, a bedroom, a kitchen, or a complete in-law apartment. 

Any addition of plumbing to the space increases the total cost. In addition, the HVAC system that you use and whether you tie the heating system with the home or use a separate system also impact the total price. 

Converting a space usually includes an exterior makeover to remove the garage door and give it the appearance of a living area rather than a garage. All these factors impact the final costs.

Cost To Convert Garage To Office

The cost to convert a garage into a home office averages $10,000 to $20,000. The cost range includes variations in how you heat and cool the space. It also considers that some garages are finished while others are unfinished. 

If the garage is insulated and has finished walls, it costs less to convert than an unfinished garage that needs insulation. Garage doors can be hard to insulate, so you likely want to remove the door, including some exterior renovation. How you finish the office and the flooring and furnishing types also impact the cost.

Cost To Convert A Garage To A Bedroom

The average cost range to convert a garage to a bedroom is between $10,000 and $20,000. Like the home office conversion, the cost of a bedroom conversion is influenced by many things. 

These include the garage’s finish level, if it is insulated and how you intend to heat and cool the bedroom. Adding a bathroom ensuite increases the project’s cost as well. How you finish the garage’s exterior also impacts the price. Most people remove the door to eliminate direct access to the bedroom from outside.

Convert A Garage Into A Bathroom

The average cost range to convert a garage into a bathroom ranges from $15,000 to $30,000. Anytime you need to run plumbing to the garage, your costs increase. You also must add an HVAC system and insulation to the area. 

Drilling through a concrete garage floor to put in a waste drain for a toilet installation can be very expensive. Bathrooms can also have a wide range of finishing costs. You have various fixtures and finishes to choose from, depending on the bathroom’s size and style.

Convert Garage Into Kitchen Cost

The average cost to convert a garage into a kitchen is $20,000 to $40,000. Like the bathroom conversion, a kitchen requires plumbing. This automatically increases the conversion cost. 

You also need to add an HVAC system and insulation and potentially a gas line. Cabinets, countertops, lighting, and flooring all have additional costs that contribute to the final cost. It would help if you also considered the conversion’s exterior work.
