About our gutter sealing in Wheathampstead
Open fascia and soffit joints spoil the roofline and can let weather in. We seal them in a colour to suit where one is available. We work on gutter joints, roofline trims and gutter end caps, and the jobs we see most are gaps along fascia and soffit joints and trim joints where the sealant has failed.
Around Wheathampstead, garages, outbuildings and extensions all add to the joints on the outside of a home. Leaks normally start at a gutter end, a garage door frame or where an extension meets the house.
Whatever the size of the job, you get the same 12-month guarantee.

Outside joints around Wheathampstead
The South East is one of the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day. Historic houses like Shaw's Corner (about 1.9 miles north-east) are a reminder that the area around Wheathampstead has older buildings as well as new. In older buildings, older walls and rooflines need a sealant that moves with them and suits the material.
If you look after a building such as St Helen's Church of England Primary School, larger buildings have long runs of movement joint that eventually need resealing. In the older streets around St Helen's Church, an extension built onto an older house moves differently, and the joint between them takes the strain. For landlords with property near Harpenden station, leaking gutter joints on a rental are best caught before they stain the walls.

What we do, step by step
Before we leave, we go over the finished joints with you and tell you how long to leave it. The work normally takes a few hours, depending on the number of joints and the access, depending on the size of the job. For a job in Wheathampstead, we agree the time, the access and parking before the day. Outdoor jobs depend on a dry day, since sealant needs a dry surface.
- We find where the water is coming from and check the gutter is sound.
- We remove the old sealant and clean the joint.
- The joint is dried before sealing.
- We seal the joint with a sealant made for gutters.
- We check the run and clear debris near the joints.
How to prepare
- On commercial sites, let us know about site rules
- Mention any parking rules near the property
- Tell us about any water getting in

Advice
What affects the cost of gutter sealing
Jobs vary more than people expect. What affects the quote:
- Whether there’s mould to deal with
- Whether the work is at height
- The product the joint needs
- When we can work, for business premises
Doing several joints on one visit is generally more efficient than separate visits. You’ll get one clear quote for the whole job.
What to tell us for a quote
Photos by email are helpful but not essential. Please mention:
- The address or postcode of the job
- How many joints, rooms or windows are involved
- How we’d reach the joints
- Whether it’s a home or a business
For a quick quote, get us on the phone, or send an email if you’d rather. Tell us about the joints that need doing and we will talk you through the work before giving you a price.

Should I try it myself first?
A DIY attempt does not rule out a professional job. We cut it out and start again.
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
Looking after it afterwards
A little care helps the new joints last. We recommend:
- Glance at the soffit joints now and then
- Deal with a drip before winter
- Keep an eye out for wet patches below a joint
- Check that water runs out of the downpipes
If a gutter starts to sag, get the brackets looked at. Movement will pull the joints open again.
Rain getting in round a garage door frame can damage what’s stored inside. Resealing the frame is a quick job while the frame is sound.
Different surfaces, different methods
uPVC fascias
Joints between fascia boards can open over time. They’re sealed tidily in a suitable colour.
Soffit joints
We choose a sealant colour that suits the soffit.
FAQs for Wheathampstead
I let a flat near Harpenden station. Can you help?
Yes, landlords and agents are among the people we work for. You can ring 0345 464 0079 or send us an email with the details for a clear quote.
Do you cover Wheathampstead for gutter sealing?
Yes, Wheathampstead is within the area we cover. We work across London and the South East. Just ring 0345 464 0079 or drop us an email with a few details of the job.
Can I add another job to the visit?
Yes, and it often makes sense. 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 and low-level gutters are straightforward. If it’s higher up, let us know and we will confirm the access.
Do you guarantee gutter sealing?
You get our one-year guarantee on every job.
Is it worth trying it myself?
Some simple jobs can be done by a careful DIYer. Most DIY failures come from sealing over old material, wet joints or too much sealant.
What information do you need?
A short description and the location, with photos by email if possible. We’ll ask anything else we need to know.
Will sealing fix a sagging gutter?
Sealant will not hold a sagging gutter. The gutter needs refixing by a gutter installer, and we’ll tell you if that’s what we find.
What happens if it’s left?
A bead squeezed onto a wet joint might hold for a while, but it soon lets go. Proper preparation is the difference. In a smaller place like Wheathampstead, 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.
What you pay reflects the work, not guesswork. That is why we ask about the job first.
