Without a doubt, one of the main elements to look for when buying a home is the envelope's energy efficiency. Besides ensuring optimal indoor temperatures, it minimizes heating and cooling needs, making the home impervious to drafts and water leaks.
Caulking is an important finishing step that will ensure the home has an airtight thermal envelope, maximizing its energy efficiency. In Canada, this is a common practice that ensures proper sealing around doors and windows, as well as exterior siding joints.
If your home is drafty or has a water leak, here and there, then it’s highly likely that your current caulking is cracked or peeling.

The cost of having a house caulked by a professional service can vary based on several factors, such as the home’s square footage and age. Plan on spending anywhere between $1,000 and $3,000 to caulk an average-sized home. The price range also depends on the degree of ease with which the joints can be removed and the gaps sealed. The cost will be higher if the gap is larger. Typically, it takes half a day to complete but can take up to two days for extensive caulking jobs.
Companies tend to use a dedicated type of sealant. For example, some use silicone-based sealants that are more eco-friendly compared to other caulking products. Note that caulking durability depends on the product warranty, which varies according to the quality of the sealant.
Tubes of Caulking Sealants: Types and Prices
Whether you apply the caulking product yourself or hire a professional to do so, note that there are different types of sealants. Prices vary depending on product composition and durability.
A thermoplastic sealant is a professional-grade product with an excellent service life. Such a versatile product adheres remarkably well to a slew of materials, including glass. Once applied, it quickly forms a dust-free film. Thermoplastic sealants are silicone-free and can stretch up to 1,400% without cracking. A 300 ml tube retails for about $8 in hardware stores.
Urethane sealants are known for their above-average resistance and durability. They have a flexible consistency and are highly resistant to cracking. Such a sealant adheres to most materials and allows a 25% range of motion. This product is available in stores for $8.50 or more, depending on the selected brand.
A latex sealant is an eco-friendly product, containing fewer than 3% volatile organic compounds. It’s ideal for exterior use, remains flexible, and is water-resistant. This sealant can be cleaned with soapy water and painted roughly 2 hours post-installation. Plan on spending about $2.75 for a 300 ml tube of latex caulk.
Noiseproofing sealants are used for both soundproofing and sealing purposes. Since this type of product is made with synthetic rubber, it won’t harden or stain and is easily applied with a caulk gun. It lasts roughly 20 years. This type of sealant runs about $5.50 for 300 ml.
What Factors Affect the Cost of Indoor and Outdoor Sealing Jobs?
Type of Work
The cost of caulking services varies significantly based on the exact work to be done. For example, sealing the perimeter of a house is a whole other ballgame compared to caulking around a window, bathtub, or shower. Generally, service rates are assessed on a project-based system: sealing a shower or tub will have similar prices, while the cost of caulking around the perimeter of a house tends to be calculated based on its length; windows are priced individually.
Caulking Product Used
As mentioned, it shouldn’t come as a surprise that prices will fluctuate based on the type of sealant or caulk used to carry out the commissioned job. Indeed, some caulking products cost three to four times that of others.
Scope of Work
Much like most remodelling or renovation projects, the scope of the work commissioned will significantly weigh on the project’s overall price tag. If there’s more work to be done, such as caulking all around a house's every single window, your invoice will be much steeper than, say, caulking around a single bathtub.
Furthermore, the bigger the job, the more sealant is needed. This will also increase costs.
What Are Potential Additional Costs?

Stripping the Old Sealant
If the old caulking bead has to be removed prior to applying the new one, doing so can potentially increase the time needed to complete the job, thereby increasing costs.
Accessibility
When assessing the service costs of caulking your home, repair site accessibility is a major contributing factor. Work requiring the use of ladders, roof access, or crawling through restricted spaces typically leads to steeper pricing, factors that will most likely be reflected in a professional quote.
Moreover, challenges related to material and tool transportation to the job site can also increase overall costs.
FAQ
What Is Silicone Sealant Used For?
Because of its waterproof properties, silicone sealants are often used in bathroom and kitchen to seal around showers, bathtubs, sinks, toilets, and more.
Why Is Silicone Sealant So Expensive?
Excluding inflation, the increased prices of silicone sealant primarily stem from supply chain issues.
How Much Does a Caulking Gun Cost?
Though the price can vary, most caulking guns are sold for around $30.
What Type of Caulking Should Be Used for the Exterior Doors and Windows of the House?
For exterior windows and doors, it's best to use silicone or silicone-latex caulks.
When Should Caulking Be Done/Redone?
The answer varies slightly depending on the location of the caulking. Whether it’s inside or outside, issues such as mould, cracks, water infiltration, gaps, air leaks, heat loss, or other damage will necessitate recaulking or, at the very least, an inspection.
For interior caulking, especially in damp environments like bathrooms, it's recommended to replace the caulking every 5 years. For exterior caulking, replacement is generally recommended every 10 years.
