About our gutter sealing in Garston
We do not replace gutters, fascias or roofs. What sealant does is close joints and it cannot mend broken brackets, split sections or blocked downpipes. We work on garage door frames, soffit joints and gutter end caps, and the jobs we see most are trim joints where the sealant has failed and leaking gutter joints and stop ends.
Houses in smaller places like Garston can stand more in the open than those in a built-up town, and walls and rooflines facing the weather take the worst of it. That’s where gutter joints and wall joints tend to fail first.
Big or small, it’s backed by our 12-month guarantee.

What happens on the day
There isn’t much for you to do on the day. Show us the job and we will take it from there. The job generally takes a few hours, depending on the number of joints and the access. In a smaller place like Garston, parking is seldom the issue; lanes, gates and long drives are worth mentioning. For outside work, side access and the height of the joints help us plan.
- We find where the water is coming from and check the gutter is sound.
- We remove the old sealant and clean the joint.
- We dry the joint so the new sealant can bond.
- A gutter sealant is applied to the joint.
- The gutter is checked and debris around the joints cleared.
Preparing for the visit
- Mention any tricky access
- Where the joints are inside, avoid wetting them before we arrive
- Move anything stored near the joints

Work for landlords, hotels and businesses

We work for landlords and letting agents as well as householders. Resealing between tenancies keeps a property looking cared for before the next move-in.

Common problems we fix in Garston
Debris in the gutter keeps water sitting at the joints. Water that can’t drain works its way through a weak joint and leaks out.
Any of these means the joints need attention:
- Water dripping where gutter sections meet
- Old sealant on roofline trims that has split
- End caps that drip every time it rains
- Wet patches on the wall under a gutter joint
Homes close to Stanborough Park Church include some older properties, and older walls, gutters and the joints where extensions meet them need a flexible sealant.

Why it’s worth doing now in Garston
Replacing fascias because of open joints is normally unnecessary. Sealing the joints tidies them up as long as the boards are in good condition. In a smaller place like Garston, wherever a wall is exposed, a failed outside joint is a real source of damp. Indoors, a failed seal lets water into floors and panels as it would anywhere.
There are no prices on our website, because each job is priced on what it involves. For a quick quote, please phone 0345 464 0079 or send us an email.

Surface by surface
Garage door frames
Resealing a garage door frame keeps rain and draughts out.
Gutter end caps
We seal end caps from the inside where we can reach, after cleaning and drying.
Should I try it myself first?
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
Sealing over old silicone is the commonest DIY error. Silicone does not stick to old silicone, so it lifts and traps water and mould underneath. Everything old must be removed first.

Outside joints around Garston
Rainfall in the South East is lower than in much of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day. With historic houses such as High Elms Manor (about 1 mile north-west) nearby, there’s older building stock in the area around Garston as well as newer homes. Where a home is older, older walls and rooflines need a sealant that moves with them and suits the material.
For landlords with property near Garston station, a dripping gutter joint or loose fascia trim is easy to miss until damp shows inside. Schools such as The Grove Academy are buildings too, and movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.
