DIY sealant or a professional job?
If you are set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions.
Gutter sealing for homes and businesses in West Twyford
Water dripping from a gutter joint can stain walls and soak the ground below. Often a reseal is enough, as long as the gutter is sound. We work on roofline trims, garage door frames and gutter end caps, and the jobs we see most are water dripping where gutter sections meet and streaks down the brickwork from a leaking joint.
In London terraces and converted houses, gutters and walls are often shared with the house next door, so a leaking gutter joint or failed wall joint can affect more than one home. For a flat in West Twyford, check the lease for who looks after the outside.
The work is covered for a year after we finish. If there’s a problem with it, please call 0345 464 0079 or email us.

When to call us in West Twyford
Water spilling over a blocked gutter is often mistaken for a leak. A blocked downpipe makes water back up so we check the cause first.
The problems people usually mention when they call are:
- Damp patches inside below a leaking gutter
- Stop ends leaking at the end of a run
- Rain getting in around a garage door
- Streaks down the brickwork from a leaking joint
Letting a property close to Stonebridge Park station? Then a gutter joint that drips onto the wall can turn into a damp complaint, so it’s worth checking.
Questions to ask before you book
- Who does the work, and how experienced they are
- Which sealant they’ll use, and why
- What the quote includes, VAT included or not
- Whether all the old sealant comes out first
What the job involves on each surface
Soffit joints
Gaps at soffit joints can let in draughts and insects. We close them with a suitable sealant.
Roofline trims
Roofline trims rely on sealant at their joints. Split sealant lets water in.
What we do, step by step
Every visit runs the same way: we check the joints, mask and protect the surrounding surfaces, do the work and clear up. It generally takes a few hours, depending on the number of joints and the access. In a London area like West Twyford, the main things to plan are parking and access: let us know about parking, the floor we’ll be working on and any lift or shared entrance.
- First we trace the drip and check the gutter is not damaged.
- The old sealant and dirt are cleaned out of the joint.
- The joint is dried before sealing.
- A gutter sealant is applied to the joint.
- The gutter is checked and debris around the joints cleared.
Preparing for the visit
- Mention any leaks or damp you’ve noticed
- Try not to wet indoor joints just before the visit
- Let us know about stairs, lifts or work at height

Why it’s worth doing now in West Twyford
If the problem is a blocked downpipe, sealing will not help. We check the cause first and point you to the right trade if needed. Converted houses in London often have a bathroom above someone else’s living room, so a small leak from tired sealant can mean a neighbour’s ceiling and a lot of disruption. Putting it right early is much less trouble for homes in West Twyford.
Leaving a failed joint generally makes the job bigger, not smaller, as water and mould keep getting in. If you are unsure, ring 0345 464 0079 or send us an email for an honest opinion and a quote.

Looking after it afterwards
A little care helps the new joints last. Our advice:
- Deal with a drip before winter
- Do not leave a sagging gutter
- Keep ladders off the guttering
- Check fascia and soffit joints for gaps
Check the joints after heavy rain. Drips are easiest to spot while it’s raining.
Leaking gutter joints get worse over time. Water keeps hitting the same part of the wall, which can lead to staining and damp.

In older buildings, older brick and stone need a sealant that suits them, at the right joint depth.
