How we handle gutter sealing in Lyneham
Our work covers gutter joints and end caps as well as fascias and soffits, along with roofline trims and garage door frames. It’s all about the joints, not replacing the gutter. If you are dealing with leaking gutter joints and stop ends and streaks down the brickwork from a leaking joint, we can help, whatever the surface.
Outside joints can only be sealed when they’re dry, so work in Lyneham is booked around the forecast. Let us know about access to every wall, plus any garages or outbuildings.
The work is guaranteed for twelve months. If something isn’t right with it in that time, tell us and we will put it right.

Work for landlords, hotels and businesses
We regularly work with letting and managing agents. Tell us the address, the job and how access works and we’ll quote.
Mouldy or split sealant often shows up at the end of a tenancy, and it’s easy to sort out between tenants. We can quote for more than one property at once.
What the job involves on each surface
Garage door frames
The joint between frame and brickwork moves and weathers. An exterior sealant suits them.
Gutter end caps
A leaking end cap sends water straight down the wall. It’s a small job to fix.
Signs you need gutter sealing in Lyneham
Sealant on fascias and trims weathers like any outdoor joint. It hardens, shrinks and splits over time.
Common reasons people contact us are:
- Old sealant on roofline trims that has split
- Water dripping where gutter sections meet
- Wet patches on the wall under a gutter joint
- Dripping gutter ends
Letting a property close to Shipton station? Then a dripping gutter joint or loose fascia trim is easy to miss until damp shows inside.
Questions to ask before booking
- What insurance they hold
- Whether all the old sealant comes out first
- Who does the work, and how experienced they are
- The length of the guarantee

Most jobs take an hour or two for a few joints, longer for a full run. Somewhere like Lyneham needs a little journey planning: let us know about lanes, gates and parking. We bring what the job needs, so it can be finished in one trip where possible.

Advice
Leave it or put it right?
A bead squeezed onto a wet joint might hold for a while, but it soon lets go. Cleaning out and drying the joint first is what makes it last. Where a wall is exposed, as many are in small places like Lyneham, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
The cost reflects the work involved, not a rough estimate. That’s why we ask a few questions first.

Your questions about gutter sealing in Lyneham
Can you help a landlord with a rental near Shipton station?
Yes, rental work is part of what we do. You can phone 0345 464 0079 or email us with the address and a few details, and we will give you a fixed price before any work starts.
Is Lyneham within the area you cover?
Yes, Lyneham is covered. We work across London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.
Is gutter cleaning part of the job?
The joints we seal are cleaned out and clear debris we find nearby. Cleaning the whole run is a different job.
What should I tell you?
Just the basics: the address or postcode, what’s wrong and any access issues. After that, simply ring 0345 464 0079 or drop us an email.
Does someone need to be in?
We need access to the joints, so we’ll agree that with you when we book. Indoors, that generally means someone at home.
What about gutters on a second or third storey?
Low-level work is easiest. For anything higher, we’ll confirm what access is needed before we book.
How much does gutter sealing cost in Lyneham?
The cost depends on the size of the job, access and how much old sealant has to come out. Ask us for a quote.
Can I add another job to the visit?
Yes. More than one area can be quoted together.
