Preventing Pests During Home Renovations and Extensions: A Newmarket Homeowner’s Guide
Newmarket is a town of constant improvement. From the restoration of historic cottages to the modern extensions being added to family homes, many residents are investing in their properties. However, there is a hidden side effect to construction that many homeowners overlook: the invitation it sends to pests.
When you open up a wall, dig up a floor, or leave a building site unattended overnight, you are essentially removing the “armour” of your home. At Newmarket Pest Solutions, we frequently see a spike in rodent activity in properties undergoing work. In this guide, we explore why renovations attract pests and how pest proofing during renovation can save you from a major headache later.
1. The “Open House” Effect: Why Construction Attracts Pests
A renovation project creates the perfect storm for pest activity. Whether you are adding a kitchen extension or converting a loft, several factors make your home a target:
Exposed Voids and Cavities
Modern and historic homes alike rely on sealed wall cavities and floor voids to remain pest-free. When a builder removes a section of the external wall or pulls up floorboards, these “highways” are exposed. Rats and mice, which are naturally curious and constantly looking for new nesting sites, will seize the opportunity to move into the quiet, undisturbed parts of your home.
Disrupted Soil and Drains
Building an extension usually involves groundwork. Digging foundations or moving drainage pipes can disturb existing rodent burrows or break old clay pipes. If a redundant drain is not capped off correctly, it becomes a direct tunnel for rats to enter your new extension from the sewer system.
Construction Waste and Food
Building sites are messy. Piles of rubble, timber, and sand provide excellent cover for pests to hide. Furthermore, if builders leave food wrappers or lunch scraps in the skips or around the site, it provides a high-calorie food source that will attract rodents from the entire neighbourhood.
2. The Dangers of “Building In” a Problem
The biggest mistake a homeowner can make is finishing a beautiful new extension without checking for pests first. Once the plasterboard is up and the new kitchen is fitted, dealing with a rat or mouse problem becomes significantly more difficult and expensive.
Gnawing at New Infrastructure
Rodents have a biological need to gnaw. In a new extension, they can quickly damage:
Plastic Plumbing Pipes: Leading to slow leaks behind new kitchen units.
Electrical Wiring: A major fire hazard, as we discussed in our post on rats chewing wires.
Insulation: Mice love to shred modern loft and wall insulation for nesting material, reducing the energy efficiency of your new room.
3. Essential Steps for Pest Proofing During Renovation
To ensure your new space remains a sanctuary, follow these proactive steps:
Cap Your Drains: If you are moving a toilet or sink, ensure the old pipes are professionally capped with concrete or a specialist metal bung. Never just “stuff” a pipe with a rag or expanding foam.
Check the Junctions: The point where your new extension meets the old house is a common weak spot. Ensure that the cavity closers are installed correctly and that there are no gaps in the masonry.
Install Rodent-Proof Mesh: Use stainless steel mesh around any new air bricks or vent openings.
Keep the Site Tidy: Ensure your contractors use lidded bins for food waste and that building materials are stored off the ground where possible.
4. Why Call a Professional During the Build?
At Newmarket Pest Solutions, we can work alongside your builders to provide a “Pest Audit” during the construction phase. We can identify vulnerabilities that a general builder might miss, such as a faulty sewer connection or a gap in the eaves of a new roof.
By installing professional pest proofing while the walls are still open, you are making a one-time investment that protects your property for decades to come.
Conclusion: Protect Your Investment
A home renovation is an exciting time, but don’t let the “guests from the garden” ruin your new space. By integrating pest prevention into your building plan, you ensure that your beautiful new extension is safe, hygienic, and structurally sound.
