Doors and windows are among the main entry points for rodents and insects into a home or business. A worn seal, an ill-fitting door sill or a cracked window surround is enough to let a mouse or column of ants through. Nova Extermination’s door and window caulking seals these openings in a lasting way, on the South Shore of Montreal and in Montérégie.
Why caulk your doors and windows
A mouse squeezes through an opening the size of a dime, and crawling insects exploit the slightest crack around the frames. In addition to pests, poor caulking also lets in cold air and humidity and increases your heating costs. Sealing these areas therefore protects against infestations and improves the comfort of the building.
How pests infiltrate through doors and windows
The most common weak points are the bottom of doors, thresholds, connections between the frame and the wall, storm windows and wiring passages near openings. Our technician inspects each of these locations to identify actual and potential accesses before intervening, in Longueuil, Boucherville, Brossard and elsewhere on the South Shore.
Our caulking service
We seal cracks and joints with suitable sealants and, for larger openings, gnawing resistant materials such as steel wool and wire mesh. We adjust or replace weather stripping and door bottoms as needed. This exclusionary approach is naturally integrated into a comprehensive prevention plan or following an extermination.
Sustainable materials, not temporary solutions
A simple foam plug or tape does not resist rodents for long. We favor durable materials and careful installation for reliable waterproofing over time. Nova Extermination is a certified company (RBQ, CNESST).

Frequently Asked Questions: Window and Door Caulking
Does caulking doors and windows really keep mice out?
Yes, by sealing doorways, sills and window surrounds with gnawing resistant materials, you remove the access that mice and insects use. This is one of the most effective exclusion measures, especially when combined with a complete inspection of the building on the South Shore.
What is the difference between caulking and simple weatherstripping?
Weatherstripping improves airtightness, but is not always enough to block rodents. Our caulking combines sealants, adjusted weatherstripping and resistant materials (steel wool, wire mesh) for both thermal and anti-pest protection in Longueuil or Boucherville.
When should you caulk your doors and windows?
Autumn is ideal, before rodents seek warmth indoors, but the intervention is relevant in any season. It is also recommended after an extermination, to avoid re-intrusion through the same openings.
Does caulking improve energy efficiency?
Yes, by blocking cold air infiltration around doors and windows, good caulking reduces heat loss and improves comfort. This is a benefit that is in addition to protection against pests.
How much does a window and door caulking service cost?
The price is established on the basis of an evaluation, depending on the number of openings to be treated, their condition and the materials required. An inspection on the South Shore allows you to put an accurate price on the work. It is a paid service carried out by certified technicians.
Do you offer a guarantee against any new intrusions?
We aim for sustainable results evaluated on a case-by-case basis, without promising an absolute guarantee, because a building evolves and new cracks can appear. Our technicians will show you the areas to be monitored after the intervention.
