How much does an Ottawa contractor charge for re-sealing all eavestrough joints on a whole house?

Re-sealing eavestrough joints on a complete house in Ottawa typically costs between $300 and $800, depending on the size of your home, number of joints, and accessibility. Most Ottawa contractors charge either a flat rate for the entire job or between $15 and $35 per joint for comprehensive sealing work.

The cost varies significantly based on your home's configuration. A typical Ottawa bungalow with 120 to 150 linear feet of eavestroughs has roughly 8 to 12 joints that need sealing, including corners, end caps, and downspout connections. This usually runs $350 to $550 for complete re-sealing. A two-storey home with 180 to 220 linear feet might have 12 to 18 joints, pushing costs to $500 to $800. Complex rooflines with multiple dormers, bay windows, or architectural features can have 20 or more joints, increasing the total accordingly.

Material choice affects pricing significantly. Most Ottawa contractors use high-quality polyurethane or silicone-based gutter sealants that remain flexible through our extreme temperature swings from minus 30 to plus 35 degrees Celsius. Premium sealants cost more upfront but last longer in Ottawa's harsh freeze-thaw cycles. Some contractors include a warranty on their sealing work, typically one to three years, which adds value but increases the initial cost.

Timing impacts your final price. Spring and early summer represent peak season when contractors discover winter damage, so expect higher rates from May through July. Fall work before freeze-up is also in high demand. Winter emergency sealing during mild spells costs significantly more due to difficult working conditions and limited material performance in cold temperatures.

The job involves more than just applying sealant. Professional re-sealing includes cleaning old, failed sealant from joints, checking for proper eavestrough slope and alignment, and ensuring downspout connections are secure. Many contractors will also inspect hangers and fascia mounting points during the sealing process, as loose eavestroughs often cause joint failures.

Consider the age and condition of your existing sealant. If your eavestroughs are more than 10 years old and have never been re-sealed, or if you notice water stains on fascia boards or basement moisture issues, joint sealing is a cost-effective maintenance step that prevents much more expensive repairs later.

For comprehensive eavestrough joint sealing, hiring a professional ensures proper surface preparation, appropriate sealant selection for Ottawa's climate, and safe access to second-storey work.
