Gutter sealing in Borehamwood
Gutter and fascia replacement is not our trade, and nor is roofing. What sealant does is close joints; it won’t fix a broken bracket, a cracked section or a blocked downpipe. We work on uPVC fascias, gutter end caps and garage door frames, and common reasons people get in touch are stop ends leaking at the end of a run and leaking gutter joints and stop ends.
Plenty of homes in a town like Borehamwood have been extended, and the joint where new wall meets old is a classic place for water to get in. Getting the joint depth right matters as much as the sealant itself.
Every job comes with a one-year guarantee, wherever you are in Hertfordshire.

What affects the cost of gutter sealing
For a quick quote, just ask. The main things that affect it are:
- Whether there’s mould to deal with
- Which sealant suits the joint
- The old material and how stubborn it is
- Access and height
Instead of a standard rate, we look at what your job involves: how many joints, what’s in them now and how we reach them. You’ll know the price before we begin.
What we need to know
When you contact us, these details help:
- What’s wrong with the joints now
- The address or postcode of the job
- The type of property
- Roughly how big the job is

DIY versus a professional finish
If you are set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it doesn’t work out, we can still put it right.
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
Surface by surface
uPVC fascias
We seal fascia joints, not replace the boards. If boards are damaged, we will tell you.

Joints between gutter lengths are the most common leak point. We clean, dry and reseal them.

Borehamwood questions
Do you work for landlords with property near Elstree & Borehamwood station?
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.
Is Borehamwood in your area for gutter sealing?
Yes. We work across London and the South East, and Borehamwood is part of that. You can phone 0345 464 0079 or email us and tell us what needs doing.
Will the old sealant be removed?
Yes, every time. New silicone doesn’t stick to old silicone, so any old material comes out before anything new goes in.
Will there be a smell?
Possibly a little. Any smell clears as the sealant cures, and ventilation helps.
What sealant do you use?
The product depends on the job: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. We use products from Arbo and Everbuild.
Will sealant fix a dripping gutter joint?
In most cases, yes. If the gutter is sagging or cracked, sealing won’t last and we will say so.
Can I do it myself?
That depends on the joint. High-level, external movement and fire-rated joints are professional jobs, while a short indoor joint may be within reach.
What about gutters on a second or third storey?
That depends on the building. Let us know the height and the ground below and we will confirm what’s needed.
What we’re called out for in Borehamwood
Roofline sealant ages in sun and rain. It goes hard, cracks and pulls away over time.
Keep an eye out for these signs:
- Damp patches inside below a leaking gutter
- Failed sealant on a garage door frame
- Drips from gutter joints and end caps
- Fascia boards with gaps between them
Homes close to All Saints church include some older properties, and old and new materials meet at the roofline and walls, which is where sealant earns its keep.
Questions to ask before booking
- Are they insured?
- What preparation is included
- Whether you can choose the colour
- Who does the work, and how experienced they are
Walls and rooflines in Borehamwood
With historic houses such as Wyllyotts Manor (about 4.3 miles north-east) nearby, there’s older building stock in the area around Borehamwood as well as newer homes. Where a home is older, older brick and stone need a sealant that suits them, at the right joint depth. 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.
Rented homes near Elstree & Borehamwood station change hands often, and a gutter joint that drips onto the wall can turn into a damp complaint, so it’s worth checking. For site and facilities teams at buildings such as St Teresa Catholic Primary School, its movement joints, gutters and trims need looking after like any other building’s.

What else we do in Borehamwood
Looking after it afterwards
Once the sealant has cured, a few habits help it last:
- Check the gutters during heavy rain
- Check that water runs out of the downpipes
- Do not leave a sagging gutter
- Watch the wall under the gutters for staining
Look at fascia and trim joints when you are checking the gutters. A small split is quicker to put right.
Once roofline sealant splits, water can get behind it. Sealing it early keeps the boards behind dry.
How it works
Once we’re on site, we compare the joints with what we discussed. If anything is different, we explain it before carrying on. Most jobs then take an hour or two for a few joints, longer for a full run. A visit in Borehamwood needs access to the work and a place to park close by. For outside work, let us know about side access, gates and any upper-floor joints.
- First, we find the drip and check the gutter isn’t cracked or sagging.
- Old sealant and dirt are removed from the joint.
- The joint is dried, because sealant won’t bond to a wet surface.
- We seal the joint with a sealant made for gutters and outdoor use.
- We look along the gutter and clear debris around the joints.
Getting ready for the visit
- On commercial sites, let us know about site rules
- Clear items away from the joints we are working on
- Let us know about stairs, lifts or work at height
