Questions from Throcking
Is Throcking within the area you cover?
Yes, smaller places are covered as well as towns. Our work covers London and the South East. Just mention lanes, gates or anything else about the route when you book.
Is there a guarantee on gutter sealing in Throcking?
All our work, in Throcking and everywhere else, comes with a 12-month guarantee. We are also fully insured and ARBOMaster approved.
Will there be a smell?
There can be a smell while the sealant cures, which fades as it sets. Opening a window helps.
I rent my home. Can I book you?
We are happy to deal with the tenant, landlord or agent. Just make sure your landlord agrees.
What does gutter sealing cost?
There’s no set price, as it depends on the job: how much there is, what’s there now, how we reach it and what it needs. We agree the price before any work begins.
Are you insured?
Yes, we are fully insured for every job we do.
Will sealant fix a dripping gutter joint?
Yes, as long as the gutter itself is in good order. We clean and dry the joint before sealing so the seal holds.
Do you install new fascias or gutters?
No, we reseal joints, end caps and trims. A gutter installer or roofer deals with replacement.
Gutter sealing in Throcking
Many dripping gutters are just a failed joint or end cap. The joint is cleaned, dried and resealed with a sealant made for guttering. If the gutter itself has failed, we say so. We work on gutter end caps, soffit joints and gutter joints, and the jobs we see most are failed sealant on a garage door frame and internal damp traced to a gutter joint.
Outside joints can only be sealed when they’re dry, so work in Throcking is booked around the forecast. Let us know about access to every wall, plus any garages or outbuildings.
Whatever the size of the job, it’s backed by our 12-month guarantee.

Should I try it myself first?
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and does not move well, and getting the depth right matters as much as the look.
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.
When to call us in Throcking
Water spilling over a blocked gutter is often mistaken for a leak. A blocked downpipe makes water back up, which is why we look before we seal.
Any of these means the joints need attention:
- Stop ends leaking at the end of a run
- Gaps along fascia and soffit joints
- Trim joints where the sealant has failed
- Streaks down the brickwork from a leaking joint
Schools such as Freman College are buildings too, and its movement joints, gutters and trims need looking after like any other building’s.

Why it’s worth doing now in Throcking
If the problem is a blocked downpipe, sealing won’t help. We check the cause first and tell you if something else is needed. Older cottages and farmhouses around Throcking can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
The cost depends on the amount of work, how hard the old material is to remove and access to the work. You will have a clear quote before any work starts, so you know where you stand.

How to look after the new joints
A little care helps the new joints last. Our advice:
- Watch the wall under the gutters for staining
- Have sagging gutters refixed early
- Check fascia and soffit joints for gaps
- Watch for drips in a downpour
Make sure downpipes are not blocked so the gutter can drain. Blockages push water back along the gutter.
Once roofline sealant splits, water can get behind it. Sealing it early keeps the boards behind dry and the wall below.
