Gutter sealing for homes and businesses in Crawley
Garage door frames let rain in when the sealant around them fails. We cut out the old sealant and reseal the frame with an exterior sealant. We work on gutter end caps, soffit joints and roofline trims, and common reasons people get in touch are earlier gutter repairs that have peeled off and streaks down the brickwork from a leaking joint.
Outside joints can only be sealed when they’re dry, so work in Crawley is booked around the forecast. Tell us about access to all sides of the building, including outbuildings and garages.
Our work is backed for twelve months.

What else we do in Crawley
Why act early in Crawley
You do not need new fascias just because the joints have opened. Sealing the joints tidies them up if the boards are sound. Where a wall is exposed, as many are in small places like Crawley, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
What you pay reflects the work, not guesswork. That’s why we ask a few questions first and agree the price before starting.
Why Crawley clients choose us

What we do, step by step
Before we leave, we go over the finished joints with you and explain the cure time. The visit itself normally takes a few hours, depending on the number of joints and the access, depending on the amount of work. Somewhere like Crawley needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.
- We start by tracing the leak and checking the gutter itself is sound.
- The joint or trim is cleaned out and old sealant removed.
- We make sure the joint is dry before sealing.
- Gutter or exterior sealant is applied and finished.
- The run is checked and any debris near the joints is cleared.
Preparing for the visit
- Tell us about any previous sealing or DIY attempts
- Where the joints are inside, avoid wetting them before we arrive
- Tell us about any water getting in

Advice
Should I try it myself first?
Sealing over old silicone is the commonest DIY error. New silicone will not bond to old, so it lifts and traps water and mould underneath. All the old material has to come out first.
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions.
How to look after the new joints
No joint lasts for ever, but care makes a real difference. Our tips:
- Make sure downpipes aren’t blocked
- Have sagging gutters refixed early
- Get leaks sealed before the wet months
- Clean out the gutters once or twice a year
If a gutter starts to sag, get the brackets looked at. Movement will pull the joints open again.
A drip from a gutter joint won’t stop on its own. The same spot gets soaked every time it rains, which can lead to staining and damp.

What the job involves on each surface
Gutter end caps
Drips from a stop end run down the brickwork. It’s a small job to fix.
Garage door frames
The joint between frame and brickwork moves and weathers. An exterior sealant suits them.
Walls and rooflines in Crawley
The South East is one of the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
In the older streets around Church of St Mary, old and new materials meet at the roofline and walls, which is where sealant earns its keep. Letting a property close to Winchester station? Then a dripping gutter joint or loose fascia trim is easy to miss until damp shows inside.
