Every house has gaps: under doors, around AC pipes, where the kitchen pipe enters the wall, between tiles and skirting, around window frames. Pests use every one of them. Sealing those gaps is the cheapest, longest-lasting pest control there is.
We do it as part of a pest treatment or as a stand-alone job, with the right material for each gap.
Why it happens in Pakistani homes and buildings
Cockroaches, ants, lizards and rodents enter through gaps and live inside them. Sealing removes both the entry and the hiding place, which is why treatment plus sealing lasts far longer than treatment alone.
Signs you need gap filling & sealing
- Pests returning soon after a treatment
- Visible gaps around pipes, frames and skirting
- Draughts and dust entering under doors
- A new house with unfinished joints
How Shield Agro does gap filling & sealing
- Inspection. We check doors, windows, wet areas, pipe entries, skirting and ventilators for gaps.
- Preparation. Old, failed sealant is cut out and surfaces are cleaned and dried.
- Sealing. Each gap is filled with the material suited to it and finished neatly.
- Door and vent proofing. Door sweeps, brush strips and ventilator mesh are fitted where needed.

What does gap filling & sealing cost in Pakistan?
Gap Filling & Sealing is priced on site after a free inspection. Priced by the number and size of gaps; usually a small addition to a pest treatment. There is no call-out charge, and the price we agree is the price you pay.
How to keep the problem from coming back
- Check behind the kitchen sink and the AC pipe holes first
- Fit brush strips under external doors
- Use the right sealant for wet areas versus dry joints
- Re-check seals after any plumbing or renovation work
Frequently asked questions
Which sealant do you use in the bathroom and kitchen?
A mould-resistant silicone in wet areas around sinks, baths and showers, and a paintable acrylic sealant on dry joints such as skirting and window frames. Pipe entries get foam or mesh backing before sealing so rodents cannot chew through.
How long before the sealant can get wet?
Silicone should be left to cure for about 24 hours before the sink or shower is used. Acrylic joints can be painted the next day. We tell you the cure time for each area before leaving.
Does sealing really help with pests?
A great deal. Cockroaches, ants, lizards and mice all enter through gaps, and a treatment lasts far longer when the entry points are closed. Sealing is included as an option with our pest treatments for that reason.
