About our gutter sealing in Redbourn
Garage door frames let rain in when the sealant around them fails. We cut out the old sealant and reseal the frame with an exterior sealant. Typical jobs include old sealant on roofline trims that has split and wet patches on the wall under a gutter joint, across roofline trims, gutter joints and uPVC fascias.
Homes around Redbourn 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.
Our work is backed for twelve months.

Should I try it myself first?
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 doesn’t work out, we can still put it right.
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.

Common questions in Redbourn
Can you do gutter sealing in Redbourn?
Yes. Our work covers London and the South East, and Redbourn is part of that. You can phone 0345 464 0079 or email us and tell us what needs doing.
Can you help a landlord with a rental near Harpenden station?
Yes, rental work is part of what we do. Just ring 0345 464 0079 or email us and tell us about the property, and we will send you a clear quote.
Do you hold any approvals?

Do you take out the old sealant first?

Do you have insurance?

What guarantee comes with the job?
Every job comes with our 12-month guarantee, and we’re fully insured.
Do I have to be there?
That depends on where the joints are. For work indoors, someone needs to let us in.
Can you seal fascia and soffit joints?
Yes, it’s a common job. Each joint is cleaned and sealed with a suitable exterior sealant.
Why act early in Redbourn
Sealant will not clear a blocked downpipe. We check the cause first and tell you if something else is needed. In an older home around Redbourn, damp from a failed joint can get into timber and plaster, which is far harder to put right than the sealant itself.
Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, any mould to treat, and whether the work is at height. We take all of that into account in your quote.

What affects the cost of gutter sealing
The price is agreed before any work begins. It’s based on:
- The number of rooms or windows
- How easy the joints are to reach
- The type of sealant required
- Whether there’s mould to deal with
Leaving a failed joint generally makes the job bigger, not smaller, because water and mould keep working on it. If you are not sure whether it needs doing, ring 0345 464 0079 or drop us an email for an honest opinion and a quote.
Asking for a quote
You don’t need to know the technical terms. Just tell us:
- The type of property
- Access, such as stairs, a lift or height
- Pictures of the joints, sent by email
- Any previous sealing or DIY work
There’s no standard price list, as no two jobs are quite the same. Instead, your job gets its own clear quote. To get started, call 0345 464 0079 or email us.
Redbourn buildings and the weather
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. With historic houses such as Childwickbury Manor (about 2.6 miles south-east) nearby, there’s older building stock in the area around Redbourn 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.
Homes close to Mount Zion Evangelical Church include some older properties, and an extension built onto an older house moves differently, and the joint between them takes the strain. Managing a site like Redbourn Primary School? Then its movement joints, gutters and trims need looking after like any other building’s.

What we’re called out for in Redbourn
Gutter joints depend on seals that wear out. Temperature changes make gutters move, and old seals crack or slip.
The problems people normally mention when they call include:
- Quick sealant fixes on gutters that didn’t last
- End caps that drip every time it rains
- Damp on an inside wall under a dripping gutter
- Gaps along fascia and soffit joints
Rented homes near Harpenden station change hands often, and a gutter joint that drips onto the wall can turn into a damp complaint, so it’s worth checking.
Comparing quotes
- Whether the sealant suits the joint
- What insurance they hold
- How long to leave it before use
- The length of the guarantee
Looking after it afterwards
Simple care keeps the joints in good condition. Our advice:
- Don’t leave a sagging gutter
- Make sure downpipes are not blocked
- Check fascia and soffit joints for gaps
- Rest ladders on the wall, not the gutter
Clear the gutters once or twice a year, so water drains away past the joints. Standing water strains every seal.
A leaking garage frame lets water reach stored items. A reseal sorts it while the frame is sound.
What happens on the day
Once we are on site, we compare the joints with what we discussed. If we find something unexpected, we talk it through with you first. Most jobs then take a few hours, depending on the number of joints and the access. For a job in Redbourn, 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 look at the gutters, fascias and trims and agree the joints to seal.
- We clean out each joint.
- We make sure everything is dry.
- We apply exterior or gutter sealant and finish it neatly.
- We check our work before we leave.
How to prepare
- Plan for the work area to be out of bounds to pets and children
