Gutter sealing in Poundon
For gutter sealant to hold, the joint has to be clean and dry. That’s why we take out the old sealant and dirt first, then dry the joint before sealing. We work on uPVC fascias, gutter joints and gutter end caps, and the jobs we see most are cracked sealant along roofline trims and leaking gutter joints and stop ends.
Around Poundon, older buildings can be stone, brick or timber-framed, many with extensions added later. Where one material meets another is where water normally gets in.
All of our work is guaranteed for twelve months, and the guarantee is the same wherever you are.

When it isn’t the sealant

The process
There’s no need to move everything out, just the space around the work. Everything nearby is protected, and the work takes anything from an hour or two to a few hours for a typical job. Somewhere as small as Poundon, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We find where the water is coming from and check the gutter is sound.
- The old sealant and dirt are cleaned out of 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.
Preparing for the visit
- On commercial sites, let us know about site rules
- Mention any parking rules near the property
- Where the joints are inside, avoid wetting them before we arrive

Advice
What affects the cost of gutter sealing
Your quote is based on your job. We take into account:
- How many areas need sealing
- Any working-time requirements on site
- The type of sealant required
- How easy the joints are to reach
We don’t show prices on the website, because the cost depends so much on the job itself. For a quick quote, please ring 0345 464 0079 or email us and we’ll talk you through it.
Helping us quote
There’s no need for technical detail. It helps if you can tell us:
- Access, such as stairs, a lift or height
- The problem you’ve noticed
- Whether it’s a home or a business
- Whether it has been sealed before
It all starts with a short chat. Tell us what’s wrong, where it is and how much there is, and we’ll explain how we’d tackle it. Whenever you’re ready, call 0345 464 0079 or drop us an email.
Outside joints around Poundon
With historic houses such as Claydon House (about 4.5 miles east) nearby, there’s older building stock in the area around Poundon as well as newer homes. In older buildings, older walls and rooflines need a sealant that moves with them and suits the material. 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.

How the job changes by surface
uPVC fascias
Gaps in fascias spoil the roofline. Sealing them closes the gap.
Roofline trims
We seal the trims, not the roof. A roofer deals with the roof itself.

Mouldy or split sealant often shows up at the end of a tenancy. We can quote for more than one property at once.
Should I try it myself first?
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
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.
