Very small, isn&#8217;t it? And above all, it is not easy to spot. The solution? The mouse caulking of your home! It is difficult <a href=\"https:\/\/www.novaextermination.com\/rongeurs-nuisibles-2\/\">to get rid of a rodent<\/a> if the source of infiltration is not blocked or clogged. Our mouse caulking service is <strong>a complete solution<\/strong> to permanently remedy your infestation problem.      <\/p>\n\n<p class=\"wp-block-paragraph\">The junction between the roof and the exterior wall of the house is where unwanted visits most often seep in. Indeed, sometimes a hollow forms there, and the mice only have to <strong>climb on the brick to get there quite easily<\/strong>. They also manage to enter the house through the chimney or ventilation dampers. Door sills and roofs are also places to which attention must be paid.   <\/p>\n\n<p class=\"wp-block-paragraph\">Here are the other animals that get into the holes in your home:<\/p>\n\n<ul class=\"wp-block-list\">\n<li>Birds<\/li>\n<li>Bat<\/li>\n<li>Flying insects (wasps, hornets, etc.)<\/li>\n<li>Crawling insects (ants, cockroaches, spiders)<\/li>\n<li>Rats  Field Mice<\/li>\n<\/ul>\n\n<h4 class=\"wp-block-heading\">Identify sources of infiltration<\/h4>\n\n<p class=\"wp-block-paragraph\">It is difficult to get rid of a rodent if the source of infiltration is not blocked, clogged or caulked. Our <a href=\"https:\/\/www.novaextermination.com\/en\/rodents\/mice-exterminator\/\"><strong>mouse or rat hole caulking<\/strong><\/a> service is a complete solution to permanently remedy your infestation problem. <\/p>\n\n<h4 class=\"wp-block-heading\">Mouse caulking<\/h4>\n\n<p class=\"wp-block-paragraph\">Once these flaws have been spotted and the undesirables have been exterminated, it is time <strong>to caulk against mice and pests<\/strong> of windows and doors as well as any other holes reported. However, we suggest that you repair an opening as soon as you spot it as a preventive measure. <strong>Have any cracks and openings repaired<\/strong> before it&#8217;s too late. A simple little hole could get you in a lot of trouble! At Nova Extermination, we have the necessary solutions to caulk the flaws, and solve your infestation problem once and for all.    <\/p>\n\n<h2 class=\"wp-block-heading\">Where we come in when we talk about caulking<\/h2>\n\n<p class=\"wp-block-paragraph\">The bulk of our caulking operations are concentrated in the immediate corridor of the South Shore. In <a href=\"https:\/\/www.novaextermination.com\/en\/exterminator-in-longueuil\/\">Longueuil (Vieux-Longueuil),<\/a> it is mainly the triplexes of Vieux-Longueuil and the bungalows of Saint-Hubert that occupy us: stone foundations, poorly jointed soffits, staggered dormers. In <a href=\"https:\/\/www.novaextermination.com\/en\/exterminator-brossard\/\">Brossard and the surrounding area<\/a>, alphabetical perimeters A to R require systematic sealing of dryer ducts and exterior plumbing entrances. Our comprehensive <a href=\"https:\/\/www.novaextermination.com\/en\/exterminateur-rive-sud-3\/\">caulking offer on the South Shore<\/a> covers the entire MRC territory, with a particular intensity in the intermediate suburbs. In <a href=\"https:\/\/www.novaextermination.com\/en\/exterminator-boucherville\/\">Boucherville and its residential neighbourhoods<\/a>, Old Boucherville and the edges of Parc national des \u00celes produce a steady stream of interventions on heritage soffits. Further east, <a href=\"https:\/\/www.novaextermination.com\/en\/exterminator-saint-jean-sur-richelieu\/\">caulking in Saint-Jean-sur-Richelieu<\/a> is heavily affecting Old Saint-Jean and Iberville, where the brick foundations have aged. Finally, our technicians regularly travel to <a href=\"https:\/\/www.novaextermination.com\/en\/exterminator-saint-hyacinthe\/\">Saint-Hyacinthe and surrounding areas<\/a> for multi-unit dwellings in the Saint-Joseph sector and farmhouses on the edge of the farm.      <\/p>\n\n<h2 class=\"wp-block-heading\">Pest Caulking Methodology: Steps and Materials<\/h2>\n\n<p class=\"wp-block-paragraph\">Effective caulking is not just about plugging a few holes: it follows a strict sequence of inspection, mapping of entry points and sealing with materials adapted to each gap. Our technicians always start with a complete diagnosis of the external perimeter of the building, starting from the ground and working up to the roof. Every sensitive junction is documented: pipe penetrations, soffits, dryer ducts, air intakes, foundation joints, dormers, concrete slabs and flashings. Mice can pass through a 6 mm hole, and crawling insects exploit cracks less than 2 mm. That&#8217;s why we map each opening accurately before choosing the right material.    <\/p>\n\n<p class=\"wp-block-paragraph\">The choice of material depends on the type of opening and the use of the area. For utility passages (pipes, electrical wires), we use stainless steel wool combined with a polyurethane sealant that is resistant to rodent chewing. For foundation cracks, a fast-setting hydraulic mortar is preferred. The soffits and roof-wall junctions are fitted with a galvanised wire mesh of at least 6 mm, mechanically fixed and caulked with a neutral silicone sealant. The basement windows and ventilation ducts are protected by screwed stainless steel grids, never simply glued. All of our materials meet the standards of the National Building Code of Canada and CMHC recommendations for the thermal envelope.     <\/p>\n\n<h2 class=\"wp-block-heading\">Reference table: typical entry points and recommended materials<\/h2>\n\n<table style=\"width:100%; border-collapse:collapse; margin:1em 0;\">\n<thead><tr style=\"background:#f5f5f5;\">\n<th style=\"padding:8px; border:1px solid #ddd; text-align:left;\">Port of entry<\/th>\n<th style=\"padding:8px; border:1px solid #ddd; text-align:left;\">Typical<\/th>\n diameter<th style=\"padding:8px; border:1px solid #ddd; text-align:left;\">Recommended<\/th>\n material<th style=\"padding:8px; border:1px solid #ddd; text-align:left;\">Target<\/th>\n species<th style=\"padding:8px; border:1px solid #ddd; text-align:left;\">Holdover time<\/th>\n<\/tr><\/thead>\n<tbody>\n<tr><td style=\"padding:8px; border:1px solid #ddd;\">Staggered Vinyl Soffit<\/td><td style=\"padding:8px; border:1px solid #ddd;\">5 to 25 mm<\/td><td style=\"padding:8px; border:1px solid #ddd;\">Galvanized Trellis 6 mm + Sealant<\/td><td style=\"padding:8px; border:1px solid #ddd;\">Mouse, Squirrels, Bats<\/td><td style=\"padding:8px; border:1px solid #ddd;\">10 to 15 years<\/td><\/tr>\n<tr style=\"background:#fafafa;\"><td style=\"padding:8px; border:1px solid #ddd;\">Passage of external hose<\/td><td style=\"padding:8px; border:1px solid #ddd;\">8 to 50 mm<\/td><td style=\"padding:8px; border:1px solid #ddd;\">Stainless steel wool + polyurethane<\/td><td style=\"padding:8px; border:1px solid #ddd;\">Mice, rats, ants<\/td><td style=\"padding:8px; border:1px solid #ddd;\">15 to 20 years<\/td><\/tr>\n<tr><td style=\"padding:8px; border:1px solid #ddd;\">Foundation crack<\/td><td style=\"padding:8px; border:1px solid #ddd;\">1 to 10 mm<\/td><td style=\"padding:8px; border:1px solid #ddd;\">Hydraulic mortar + epoxy<\/td><td style=\"padding:8px; border:1px solid #ddd;\">Ants, crawling insects, mice<\/td><td style=\"padding:8px; border:1px solid #ddd;\">20 to 30 years<\/td> old<\/tr>\n<tr style=\"background:#fafafa;\"><td style=\"padding:8px; border:1px solid #ddd;\">Dryer duct<\/td><td style=\"padding:8px; border:1px solid #ddd;\">100 mm<\/td><td style=\"padding:8px; border:1px solid #ddd;\">Check valve + stainless steel grid<\/td><td style=\"padding:8px; border:1px solid #ddd;\">Birds, squirrels, mice<\/td><td style=\"padding:8px; border:1px solid #ddd;\">8 to 12 years old<\/td><\/tr>\n<tr><td style=\"padding:8px; border:1px solid #ddd;\">Brick basement<\/td><td style=\"padding:8px; border:1px solid #ddd;\">200 to 400 mm<\/td><td style=\"padding:8px; border:1px solid #ddd;\">Metal screen grid 3 mm<\/td><td style=\"padding:8px; border:1px solid #ddd;\">Mice, rats, raccoons<\/td><td style=\"padding:8px; border:1px solid #ddd;\">15 to 25 years<\/td><\/tr>\n<tr style=\"background:#fafafa;\"><td style=\"padding:8px; border:1px solid #ddd;\">Concrete slab joint<\/td><td style=\"padding:8px; border:1px solid #ddd;\">3 to 15 mm<\/td><td style=\"padding:8px; border:1px solid #ddd;\">Exterior polyurethane sealant<\/td><td style=\"padding:8px; border:1px solid #ddd;\">Carpenter ants, earwigs<\/td><td style=\"padding:8px; border:1px solid #ddd;\">10 to 15 years<\/td><\/tr>\n<\/tbody>\n<\/table>\n\n<h2 class=\"wp-block-heading\">Caulking: pricing and duration of intervention<\/h2>\n\n<p class=\"wp-block-paragraph\">In Quebec, a complete anti-pest caulking on a single-family home is based on evaluation, depending on the size of the perimeter and the number of entry points identified. A duplex or triplex in a dense urban area (Plateau, Vieux-Longueuil, Vieux-Saint-Lambert) varies on evaluation, due to the complexity of the multiple soffits and stone foundations. A condominium or a commercial building is subject to a specific estimate after inspection. The intervention typically lasts between 4 and 9 hours for a standard house, and between 1 and 3 days for multi-unit buildings. All our work complies with CNESST safety protocols, particularly for working at height and the use of articulated ladders above 3 meters. Depending on the case, we can provide a before\/after photographic report and a guarantee on the treated areas.     <\/p>\n\n<h2 class=\"wp-block-heading\">Did you know?<\/h2>\n\n<p class=\"wp-block-paragraph\">Mice leave odors so that other mice know where to find them. This is why an infestation problem will return, even if the mice are exterminated. That&#8217;s why finding and caulking the entry points against mice is important!  <\/p>\n\n<h2 class=\"wp-block-heading\">Mouse and pest caulking: get information<\/h2>\n\n<p class=\"wp-block-paragraph\">Contact Nova Extermination at 1-844-880-6682 or 514-MON-NOVA for emergency service.
