About our gutter sealing in Sandwich
Sealant only bonds to a clean, dry joint. So the old sealant and grime come out first, then dry the joint before sealing. We work on soffit joints, uPVC fascias and gutter joints, and the jobs we see most are open joints in fascias and soffits and cracked sealant along roofline trims.
Around Sandwich, garages, outbuildings and extensions all add to the joints on the outside of a home. Leaks normally start at a gutter end, a garage door frame or where an extension meets the house.
You are covered for a year from the day we finish. If there’s a problem with it, please ring 0345 464 0079 or email us.

What we do, step by step
We bring everything the job needs with us, so there’s nothing for you to buy. Once we’ve agreed what’s being done, we protect the area and start. It normally takes anything from an hour or two to a few hours. Parking around Sandwich is generally easier than in a town centre, but mention any lanes, gates or long drives. For outside work, side access and the height of the joints help us plan.
- We look at where the water is coming from and check the gutter is not broken or sagging.
- We clean out the joint and take out the old sealant.
- The joint is dried, because sealant will not bond to a wet surface.
- Gutter or exterior sealant is applied and finished.
- The run is checked and any debris near the joints is cleared.
Preparing for the visit
- For indoor joints, keep the area dry beforehand if you can
- Keep children and pets away from the work area
- Clear the area around the work

Advice
Why it’s worth doing now in Sandwich
If the problem is a blocked downpipe, sealing won’t help. We look at what’s really happening and point you to the right trade if needed. In an older home around Sandwich, damp from a failed joint can get into timber and plaster, and that’s a much bigger job than renewing the sealant.
No two jobs are quite the same, so each one gets its own quote. The number of joints, how easy they are to reach and the sealant needed all make a difference, and we will explain the quote if you ask.
Why book with us
- Neat joints and a tidy finish
- An ARBOMaster approved applicator
- White, clear, grey or coloured to suit, where the product allows
- Experience in homes, commercial sites and hotels
Keeping the joints in good condition
Looking after new joints is easy, and it makes a real difference:
- Check the gutters during heavy rain
- Keep an eye out for wet patches below a joint
- Sort out a dripping joint early
- Look along the fascias for open joints
Check the joints after heavy rain. Drips are easiest to spot while it’s raining.
The sooner a gutter leak is sealed, the less water reaches the wall. If we find a bigger problem, we’ll tell you.
DIY sealant or a professional job?
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
Sealing over old silicone is the commonest DIY error. New silicone will not bond to old, so it peels away and traps moisture behind it. Everything old must be removed first.
What gutter sealing looks like in Sandwich
Sandwich is close to the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. That is hard on gutter, fascia and roofline joints, especially on the side facing the sea. London and the South East are among the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
Schools such as Sandwich Infant School are buildings too, and larger buildings have long runs of movement joint that eventually need resealing. Letting a property close to Sandwich station? Then a gutter joint that drips onto the wall can turn into a damp complaint, so it’s worth checking. If you live in an older home near Sandwich United Reformed Church, the joints between older walls, newer extensions and the roofline need a sealant that can move.
