About our gutter sealing in Bishop's Waltham
Open fascia and soffit joints spoil the roofline and can let weather in. We seal them in a colour to suit where possible. If you’re dealing with cracked sealant along roofline trims and open joints in fascias and soffits, we can put it right, on garage door frames, gutter joints and soffit joints alike.
Homes around Bishop's Waltham range from older cottages to newer houses, with walls and rooflines of every type. Older homes need their gutter and trim joints kept tight, newer ones their movement joints.
The work is covered for a year after we finish. If anything is not right with it, ring 0345 464 0079 or send us an email.

What we do, step by step
All our tools and materials come with us in the van. Once we’ve agreed what’s being done, we protect the area and start. It normally takes an hour or two for a few joints, longer for a full run. For a job in Bishop's Waltham, we agree the time, the access and parking before the day. If the work is outside, the weather plays a part, as sealant needs a dry surface.
- We find where the water is coming from and check the gutter is sound.
- The old sealant and dirt are cleaned out of the joint.
- We dry the joint so the new sealant can bond.
- We seal the joint with a sealant made for gutters.
- The gutter is checked and debris around the joints cleared.
Before we arrive
- Keep children and pets away from the work area
- Let us know about earlier repairs to the joints
- Tell us about any water getting in
Getting a quote
A good description makes for an accurate quote. Let us know the location, the problem and roughly how many joints, and email pictures if that’s easy.
Advice
Can I do it myself?
If you do try it yourself, take your time over the 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.
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.
Outside joints around Bishop's Waltham
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.
Managing a site like Bishop's Waltham Junior School? Then its movement joints, gutters and trims need looking after like any other building’s. In the older streets around Church of St Peter, old and new materials meet at the roofline and walls, which is where sealant earns its keep.

Looking after it afterwards
How long the joints last depends on use and care. We suggest:
- Check that water runs out of the downpipes
- Keep the gutters clear of debris
- Keep ladders off the guttering
- Watch for drips in a downpour
A sagging gutter needs its brackets checked. If it drops, the joints will open.
Leaking gutter joints get worse over time. The same spot gets soaked every time it rains and that can cause damp inside.

Do you seal gaps in fascias and soffits?
Yes. Open joints along uPVC fascias and soffits can be sealed in a matching colour.

Not at all. We work neatly, protect the area around the joints and tidy up afterwards.

We work for landlords and agents as well as homeowners. Resealing between tenancies keeps a property looking cared for.
What we are called out for in Bishop's Waltham
When a gutter sags, its joints open. Resealing a sagging joint won’t last so the brackets need attention first.
Any of these means the joints need attention:
- Open joints in fascias and soffits
- Streaks down the brickwork from a leaking joint
- Stop ends leaking at the end of a run
- Damp on an inside wall under a dripping gutter
Letting a property close to Botley station? Then a gutter joint that drips onto the wall can turn into a damp complaint, so it’s worth checking.
What to look for in a quote
- What product goes in the joint
- Whether they’re fully insured
- Whether all the old sealant comes out first
- How much experience the applicator has
Leave it or put it right?
A new garage door isn’t needed for a leaking frame. Sealing the frame generally stops it, if the frame itself is sound. Around Bishop's Waltham, water from a failed joint in an older home can soak into timber and plaster, which is far harder to put right than the sealant itself.
Combining jobs into one visit is normally more efficient than separate visits, so tell us about everything that needs sealing. We will send you a clear quote for the lot.

What the job involves on each surface
uPVC fascias
Our work is the joints, not new fascias. Damaged boards need replacing by an installer.
Gutter end caps
End caps take the pressure of water running along the gutter. When their seal fails, they drip.
