How we handle gutter sealing in Longstock
Across Longstock, we reseal gutter joints, end caps and roofline trims. Single-storey and low gutters are simple to reach, and for higher work, tell us about access and we’ll confirm what’s needed. We work on uPVC fascias, soffit joints and gutter end caps, and the jobs we see most are open joints in fascias and soffits and dripping gutter ends.
Somewhere as small as Longstock, homes and farm buildings often face open ground, so walls and rooflines take the full force of wind and rain. Gutter joints and wall joints there need a sealant that can flex and stay put.
All of our work is guaranteed for twelve months, in Longstock and everywhere else we cover.

What gutter sealing looks like in Longstock
London and the South East are among the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
For an older house near a landmark such as Church of St Mary, an extension built onto an older house moves differently, and the joint between them takes the strain. Schools such as Test Valley School are buildings too, and movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.

Questions from Longstock
Will you come out to Longstock?
Yes. Longstock is within the area we cover, which takes in towns, villages and rural addresses. Our work covers London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
What guarantee comes with gutter sealing in Longstock?
All our work, in Longstock and everywhere else, comes with a 12-month guarantee. We are also fully insured and ARBOMaster approved.
Can you fit new guttering?
That is not something we do. Our work is sealing joints and replacement is a job for an installer.
Can you quote for more than one area?
Yes. Tell us about everything you’d like done and we will quote it together.
Is gutter cleaning part of the job?
We clear debris around the joints we are sealing. Full gutter cleaning is a separate job.
Do you take out the old sealant first?
Yes. Sealing over the old bead is the commonest cause of early failure, and it’s something we never do.
Can landlords and businesses book you?
Yes. As well as householders, we work for landlords, agents, businesses and hotels in Longstock.
Will you leave a mess?
No. The area is protected while we work and cleaned up afterwards.
What happens on the day
Every visit runs the same way: we look at the joints together, protect the area around them, do the work and tidy away. It usually takes anything from an hour or two to a few hours. Somewhere like Longstock 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.
- First, we find the drip and check the gutter isn’t cracked or sagging.
- We clean out the joint and take out the old sealant.
- The joint is dried, because sealant won’t bond to a wet surface.
- We seal the joint with a sealant made for gutters and outdoor use.
- The run is checked and any debris near the joints is cleared.
Before we arrive
- Tell us about access, such as stairs, a lift or high-level joints
- Move anything stored near the joints
- Where the joints are inside, avoid wetting them before we arrive

Related advice
DIY sealant or a professional job?
If you’re set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it does not work out, we can still put it right.
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and does not move well, and the joint depth matters as much as the finish.
Aftercare tips
Once the sealant has cured, a few habits help it last:
- Glance at the soffit joints now and then
- Have sagging gutters refixed early
- Make sure downpipes aren’t blocked
- Look for streaks or damp on the wall below gutters
Make sure downpipes are not blocked so the gutter can drain. A blocked pipe backs water up to the joints.
A drip from a gutter joint won’t stop on its own. The same spot gets soaked every time it rains and that can cause damp inside.
How we quote for gutter sealing
For a quick quote, just ask. What matters most is:
- The product the joint needs
- Working hours on commercial sites
- How easy the joints are to reach
- Mould in or behind the old joints
Instead of a standard rate, we price the job in front of us: the amount of work, the old material and the access. The price is agreed before we begin.
What to tell us for a quote
When you call or email, it’s useful to know:
- Roughly how big the job is
- Any access issues, like height or stairs
- The problem you’ve noticed
- The address or postcode of the job

Landlord and commercial work in Longstock
A neglected joint can let water reach the structure, which is a bigger problem in a rented property. Keeping joints in good order is simple maintenance that we can handle for you.
Hotels need rooms back in use, so the work can be planned room by room. Hotel work is part of what we do, alongside homes and businesses.
What sealant work cannot fix
Some problems need a builder, plumber or other trade rather than us:
- Downpipes that are blocked or broken
- Roof leaks, slipped tiles or failed flashing (a roofer’s job)
- Cracked, split or warped gutter sections
If you’re not sure, just call 0345 464 0079 or send us an email and we will give you a straight answer before you book.
What we seal

What else we do in Longstock
Why act early in Longstock
Replacing guttering is a much bigger job than sealing joints. Where the gutter is in good order and only a joint leaks a reseal is all it needs. If it has failed, we’ll tell you. Around Longstock, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
No two jobs are quite the same, so each one gets its own quote. The number of joints, how easy they are to reach and the sealant needed all make a difference.
