Rat Proofing in Hazlemere (HP15) — Entry Point Sealing That Lasts
Getting rid of a few rats is easy. Stopping the re-entry is what saves you money. Our Hazlemere team surveys your property, proves the access routes, and seals them with rodent-resistant materials—not the “foam and pray” approach you’ve seen elsewhere.
Already mid-infestation? We can combine proofing with our Professional Rat Control so you’re not chasing your tail.
Typical Rat Entry Points We See in HP15 Homes
- Air bricks & vents: damaged clay vents, oversized modern grills, low vents near planting
- Pipe penetrations: gaps around waste/soil pipes, heating and AC lines, redundant holes
- Sub-floor & cavities: missing weep guards, broken air bricks, gaps at DPC level
- Rooflines: lifted tiles, eaves gaps, soffit breaks, boxed-in soil stacks
- Outbuildings: shed bases, compost bays, bin stores and garage thresholds
- Drains: cracked laterals or shared runs that allow sewer ingress (often needs a blocker)
How We Diagnose the Actual Route (No Guesswork)
- Evidence sweep: smear marks, tracking, droppings, gnaw signatures
- Void checks: endoscope/borescope into boxed runs and cavities
- Flow tests: smoke/air tests where drafts are suspected
- Drain mapping: dye/CCTV if sewer ingress is on the cards
- Plan of works: staged proofing to avoid trapping live rodents
What We Use to Seal (and Why It Holds Up)
- Stainless or welded mesh (proper gauge) set into mortar/frames for vents & openings
- Metal escutcheons/collars and cementitious fillers around pipes and chases
- Rodent-proof plates for larger defects and redundant penetrations
- Upgraded air brick covers that maintain airflow but block access
- Roofline repairs to eaves/soffits where daylight is visible
Expanding foam is used only as a backing where appropriate—never as the finished barrier. Rats can shred it in minutes.
Garden Drivers We Tackle Too
Outside conditions keep infestations going. We address:
- Under-shed burrows and slab voids (mesh skirts and ground works)
- Bird feeder positioning and bin hygiene to cut food supply
- Gaps to garage doors and outbuilding thresholds
Pair Proofing With Control & Drain Protection
For a permanent result, we remove the current population while we close the routes, and where needed we add drain protection with a non-return rat blocker. See our Rat Control page for options.
Pricing, Warranty & Discretion
- Fixed quotes after survey—no surprises
- Workmanship warranty on all sealed points
- Unmarked vehicles available on request

FAQs
Can you proof if rats are still active?
Yes—proofing is staged alongside control so we don’t trap rodents inside new barriers. We’ll set the sequence during the survey.
Will vent covers reduce airflow?
No. We use purpose-made guards that maintain ventilation while blocking access.
Do you use expanding foam?
Only as a backing where suitable. The final barrier is always metal/mesh/mortar so it can’t be gnawed through.
Do I need a rat blocker for the drains?
If signs point to sewer ingress, yes. We can run a quick trace/CCTV and install a stainless non-return valve to stop re-entry.
How long does the work take?
Most homes are completed in a single visit; roofline or structural repairs may require a follow-up. You’ll get a clear timeline with the quote.
