Gutter sealing for homes and businesses in Over Wallop
A leaking gutter joint marks the wall and wets the ground underneath. Often a reseal is enough, as long as the gutter is sound. We work on uPVC fascias, soffit joints and roofline trims, and people most often call us about water running down the wall below the gutter and internal damp traced to a gutter joint.
Outside joints can only be sealed when they’re dry, so work in Over Wallop is booked around the forecast. Tell us about access to all sides of the building, including outbuildings and garages.
The work is guaranteed for twelve months. If there’s a problem with our work within the year, let us know and we’ll sort it.

Work for landlords, hotels and businesses

A neglected joint can let water reach the structure, which is a bigger problem in a rented property. Resealing at the right time is simple maintenance.
Common questions in Over Wallop
Is Over Wallop in your area for gutter sealing?
Yes, Over Wallop is within the area we cover. Our work covers London and the South East. You can phone 0345 464 0079 or drop us an email and let us know what needs doing, and we will send you a clear quote.
Do you work for landlords with property near Grateley station?
Yes, landlords and agents are among the people we work for. Just call 0345 464 0079 or email us with the address and what needs doing, and we will give you a clear price.
Can new sealant go over the old?
No. Fresh sealant doesn’t stick to old sealant, and anything trapped underneath, including mould and water, stays there. We remove it all first.
How long does the job take?
It depends on the size of the job, but most jobs take an hour or two for a few joints, longer for a full run. We will tell you when we quote.
Do you clean gutters?
We clean the joints we’re sealing and any debris nearby is cleared. Cleaning the whole run is a different job.
Can you do several jobs on one visit?
Of course. Combining jobs makes good use of the visit, so mention them when you ask for a quote.
What about gutters on a second or third storey?
Single-storey work is the most straightforward. For anything higher, we will confirm what access is needed before we book.
What do you put in the joint?
It depends on the joint: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. We use products from Arbo and Everbuild.
DIY sealant or a professional job?
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
The biggest DIY mistake is sealing over old sealant. Silicone does not stick to old silicone, so it lifts and traps water and mould underneath. All the old material has to come out first.
Why it’s worth doing now in Over Wallop
A dripping stop end can soak the wall right through the wet months. Resealing it is a quick job compared with treating damp later. Where a wall is exposed, as many are in small places like Over Wallop, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
The cost reflects the work involved, not a rough estimate. That’s why we ask about the job first and agree the price before starting.

When it is not the sealant
Sealant isn’t the answer to every problem, and we’d rather say so up front. It won’t solve:
- Roof leaks, slipped tiles or failed flashing (a roofer’s job)
- Sagging gutters or broken brackets
- Blocked downpipes
If you’re not sure, just phone 0345 464 0079 or drop us an email and we’ll give you a straight answer before you book.

Walls and rooflines in Over Wallop
Rainfall in the South East is lower than in much of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
In the older streets around Church of St Peter, an extension built onto an older house moves differently, and the joint between them takes the strain. For site and facilities teams at buildings such as Wallop Primary School, movement joints, cladding joints and gutters on larger buildings need the same care as a house’s. Letting a property close to Grateley station? Then a gutter joint that drips onto the wall can turn into a damp complaint, so it’s worth checking.

Keeping the joints in good condition
How long the joints last depends on use and care. Here’s what we suggest:
- Have sagging gutters refixed early
- Deal with a drip before winter
- Check that water runs out of the downpipes
- Check fascia and soffit joints for gaps
Clear the gutters once or twice a year, so water drains away past the joints. Water left in a gutter tests every joint.
A drip from a gutter joint will not stop on its own. Water keeps hitting the same part of the wall, which can lead to staining and damp.
