Why Decontamination Matters

• Health risks: Rat droppings and urine can carry pathogens.
• Odour & flies: Soiled insulation holds smell and attracts blowflies.
• Heat loss: Compressed, gnawed insulation performs poorly.
• Property value: A clean, documented loft helps for sales and surveys.

Our Loft Clean-Up Process

1. Survey & quote: Assess contamination, access and proofing needs.
2. PPE & containment: Sheeting at access points; technicians work in full PPE.
3. Insulation removal: Lift and bag contaminated insulation for licensed disposal.
4. HEPA vacuuming: Fine-particulate removal from joists, sarking and voids.
5. Biocidal treatment: Targeted application to surfaces and hotspots.
6. Odour neutralisation: Breaks down smell at source (no masking sprays).
7. Re-insulation: Install new insulation to current recommended depths.
8. Proofing: Seal obvious gnaw points/penetrations; advise further works.
9. Report: Photos, findings and recommendations for your records.

What It Costs & How Long It Takes

Pricing depends on loft size, access and contamination level. Most homes are completed in a single day. You’ll get a fixed quote after survey—no surprises.

Before We Arrive

• Clear the area below the loft hatch for safe access.
• Keep pets/children away from the workspace.
• Tell us about any known electrical issues or delicate cabling in the loft.

Pair With Prevention

Loft contamination is a symptom. We can fit air brick guards, seal pipe penetrations, and—if sewer ingress is suspected—recommend a Rat Blocker for drains. See our Rat Control for complete protection.

Service Area

Dunstable, Houghton Regis, Tithe Farm, Downside, Sewell, Kensworth and surrounding LU5–LU6 postcodes.

FAQs

Do you have to remove all the insulation?

If contamination is localised, we can remove only affected sections. Heavy activity usually means a full strip, HEPA clean and re-insulate to guarantee results.

Will the smell go completely?

Yes—post clean and neutralisation, residual odour typically fades within days as ventilation improves.

Can you do this if rats are still present?

We can, but it’s smarter to remove the active population first so you’re not re-soiling new insulation.

What happens to the waste?

All contaminated insulation and debris are bagged and removed for licensed disposal. Paperwork available on request.

Do you offer discreet service?

Yes—unmarked vehicles available. Technicians work quietly and cleanly.

What We Class as “Entry Points”

• Air bricks & vents (broken, oversized or low to ground)
• Pipe penetrations (waste, soil, heating, AC, redundant pipes)
• Cavity breaks & sub-floor vents
• Damaged brickwork, gnawed sills and gaps around doors
• Roofline gaps (eaves, soffits, lifted tiles) and boxed-in pipe runs
• Drains & sewers (paired with control or a rat blocker if needed)

We don’t guess—we test, trace and prove the route before sealing.

Our Proofing Method (No Foam & Hope)

1. Full survey: Track marks, smear lines, burrows, droppings, gnaw points.
2. Route confirmation: Smoke/air checks, endoscope/thermal where needed.
3. Material selection: Stainless steel mesh, welded mesh grills, rodent-proof plates, mortar/cementitious fillers, steel wool composites—no plain expanding foam.
4. Professional install: Vent guards, pipe collars/escutcheons, brick repairs, sub-floor vent upgrades.
5. Validation: Re-inspect interior activity and set monitors where appropriate.

Garden & Outbuilding Proofing

We also deal with the outdoor drivers that keep reinfesting homes:

• Compost bays and under-shed burrows (burrow collapse and mesh skirts)
• Food sources: bird feeders, pet food, bin storage recommendations
• Outbuilding door thresholds and gnaw-resistant trim

Pair Proofing With Control for a Permanent Result

Proofing is most effective alongside an active rat control programme to remove the current population while we close routes. Where sewer ingress is suspected, we’ll recommend a rat blocker or drain checks.

Pricing, Guarantees & Access

• Fixed quotes after survey—no surprises
• Workmanship guarantee on all sealed points
• Discreet service; unmarked vehicles available on request

FAQs

Can rats chew through your materials?

No. We use stainless/welded mesh, metal plates and cementitious fillers designed for rodent resistance.

Will you proof even if I still have activity?

Yes—but we’ll combine it with control so you don’t trap rodents inside new barriers. We’ll advise the order of works on survey.

Do I need a drain blocker as well?

Only if the survey points to sewer ingress. If so, we can install a rat blocker and provide CCTV if required.

How long does proofing take?

Most homes are completed in one visit; complex properties or roofline repairs may take longer. You’ll get a clear timeline with the quote.
