Gutter Sealing in Lemsford
Professional gutter sealing in and around Lemsford, with old sealant always removed completely and a 12-month guarantee.
- Fascia boards with gaps between them
- Garage door frames letting rain in
- Old sealant on roofline trims that has split
Gutter sealing in Lemsford, done properly
We don’t replace gutters, fascias or roofs. Sealant fixes joints and it can’t mend broken brackets, split sections or blocked downpipes. Typical jobs include gaps along fascia and soffit joints and garage door frames letting rain in, across gutter end caps, uPVC fascias and roofline trims.
Around Lemsford, older buildings can be stone, brick or timber-framed, many with extensions added later. The joints where those materials meet are the weak points, and they need the right sealant at the right depth.
You get a one-year guarantee, the same in Lemsford as everywhere else we work.

FAQs for Lemsford
Do you work for landlords with property near Welwyn Garden City station?
Yes. We work for landlords and agents as well as homeowners, and several properties can be quoted together. Just ring 0345 464 0079 or send us an email with the address and what needs doing, and we’ll give you a clear quote.
Can you do gutter sealing in Lemsford?
Yes. We work across London and the South East, and Lemsford is part of that. Just phone 0345 464 0079 or send us an email with a few details of the job, and we’ll give you a clear price.
Can new sealant go over the old?
No. We remove every bit of old sealant first.
Is it possible to stop a gutter joint dripping with sealant?
Most of the time. If the gutter is sagging or cracked, sealing won’t last and we’ll say so.
Will it make a mess?
No. We protect the surfaces around the joints, and we tidy up before we go.
What do you need from me for a quote?
The location, the problem and the rough size of the job. Photos by email help too.
Can you match the sealant colour?
We help you choose a colour that suits, from white and clear to greys and other shades. The choice depends on the product the joint needs.
Is it worth trying it myself?
That depends on the joint. High-level, external movement and fire-rated joints are professional jobs.

When to call us in Lemsford
End caps get knocked or pushed by water. Once the seal behind them fails, they drip.
Common reasons people contact us are:
- Old sealant on roofline trims that has split
- Leaking gutter joints and stop ends
- Damp patches inside below a leaking gutter
- Dripping gutter ends
For an older house near a landmark such as Church of St John the Evangelist, the joints between older walls, newer extensions and the roofline need a sealant that can move.
Questions to ask before booking
- What product goes in the joint
- What preparation is included
- Whether VAT is included
- What happens if the job turns out different
The process
You do not need to clear the whole room or building, just the space around the work. We protect the rest, and the work takes an hour or two for a few joints, longer for a full run for a typical job. For a village or hamlet like Lemsford, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. We bring what the job needs, so it can be finished in one trip where possible.
- We find where the water is coming from and check the gutter is sound.
- We remove the old sealant and clean the joint.
- We dry the joint so the new sealant can bond.
- We seal the joint with a sealant made for gutters.
- We check the run and clear debris near the joints.
Getting ready for the visit
- Let us know if you’ve seen damp or leaks
- Clear the area around the work
- Mention any tricky access

DIY sealant or a professional job?
A DIY attempt doesn’t rule out a professional job. We remove it and do the joint properly, so just mention it when you contact us.

How the job changes by surface
Gutter end caps
Stop ends hold back water at the end of a run. When their seal fails, they drip.
Soffit joints
Soffit board joints can separate over time. They’re sealed to tidy the line.
What we cannot put right
We will not take on work that will not last, so these are the limits:
- Roof leaks, slipped tiles or failed flashing (a roofer’s job)
- Guttering that needs replacing
- Blocked downpipes
Not sure which it is? You can call 0345 464 0079 or email us and we will tell you honestly.

Gutter sealing in Lemsford: local notes
Historic houses like Digswell House (about 1.9 miles north-east) are a reminder that the area around Lemsford has older buildings as well as new. 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, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
Managing a site like Applecroft School? Then its movement joints, gutters and trims need looking after like any other building’s. Letting a property close to Welwyn Garden City station? Then a dripping gutter joint or loose fascia trim is easy to miss until damp shows inside.
