How we handle gutter sealing in Digswell
Failed sealant round a garage door frame lets rain blow in. We cut out the old sealant and reseal the frame with an exterior sealant. Typical jobs include streaks down the brickwork from a leaking joint and stop ends leaking at the end of a run, across gutter end caps, uPVC fascias and garage door frames.
Houses in smaller places like Digswell 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.
We stand behind the work with a one-year guarantee, so you’re not left on your own once the job is done.

Keeping the joints in good condition
Once the sealant has cured, a few habits help it last:
- Look for streaks or damp on the wall below gutters
- Get leaks sealed before the wet months
- Check fascia and soffit joints for gaps
- Keep downpipes clear
Give the sealant the cure time we tell you and avoid disturbing it.
Leaking gutter joints get worse over time. The same spot gets soaked every time it rains, which can lead to staining and damp.

What else we do in Digswell
Can I do it myself?
The biggest DIY mistake is sealing over old sealant. New silicone won’t bond to old, so it lifts and traps water and mould underneath. Everything old must be removed first.
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
What affects the quote in Digswell
For a quick quote, just ask. The main things that affect it are:
- Which sealant suits the joint
- Any working-time requirements on site
- The number of rooms or windows
- Whether there’s mould to deal with
The cost depends on the size of the job, how much old material has to come out and how easy the joints are to reach. You’ll have a clear quote before any work starts, so you know where you stand.
Asking for a quote
There’s no need for technical detail. It helps if you can tell us:
- Photos by email, if that is easy
- Access, such as stairs, a lift or height
- The type of property
- Where the job is, and your postcode
Asking for a quote is easy: let us know the job and the location and its rough size. Photos by email help us understand the job, and we will take it from there.
Gutter sealing in Digswell: local notes
Compared with the north and west, the South East gets less rain, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast. Welwyn Garden City, which Digswell is part of, was laid out as a garden city in the early twentieth century. Its houses span the original garden city homes and later estates, so outside joints of every age need looking after.
If you look after a building such as Harwood Hill Junior Mixed Infant and Nursery School, larger buildings have long runs of movement joint that eventually need resealing. Rented homes near Welwyn North station change hands often, and a dripping gutter joint or loose fascia trim is easy to miss until damp shows inside. If you live in an older home near Digswell Village Church, the joints between older walls, newer extensions and the roofline need a sealant that can move.

Why it’s worth doing now in Digswell
You do not need to replace a garage door because rain gets in round the frame. Resealing the frame joint is often enough, if the frame itself is sound. Around Digswell, water from a failed joint in an older home can soak into timber and plaster, and that’s a much bigger job than renewing the sealant.
Leaving a failed joint generally makes the job bigger, not smaller, because water and mould keep working on it. If you are unsure, call 0345 464 0079 or send us an email and we will give you an honest view and a quote.

The process
All our tools and materials come with us in the van, so you don’t need to buy or prepare anything. After a quick look at the joints together, we protect the area and start.
