About our gutter sealing in Hilsea
A lot of gutter leaks come down to one tired joint. The joint is cleaned, dried and resealed with a sealant made for guttering. If the gutter is broken or sagging, we’ll tell you. Typical jobs include internal damp traced to a gutter joint and leaking gutter joints and stop ends, on roofline trims, gutter end caps and soffit joints.
Homes around Hilsea range from older cottages to newer houses, with walls and rooflines of every type. Older gutters and trims need their joints resealed; newer brick and render need their movement joints kept sound.
All our work is covered by our one-year guarantee.

How the visit works
The work is kept neat and contained to the joints we’re treating, so you can get on with your day. Expect the work to take a few hours, depending on the number of joints and the access, and we explain the cure time before we leave. A visit to Hilsea is planned like any other: the time, the access and where to park are agreed in advance. Outdoor jobs depend on a dry day, since sealant needs a dry surface.
- 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.
- The gutter is checked and debris around the joints cleared.
Getting ready for the visit
- Let us know about parking restrictions
- Keep pets and children clear of the area while we work
- Where the joints are inside, avoid wetting them before we arrive

Surface by surface
Gutter joints
Joints between gutter lengths are the most common leak point. We clean, dry and reseal them.
Roofline trims
We seal the trims, not the roof. Roofing problems need a roofer.
When to call us in Hilsea
Roofline sealant ages in sun and rain. It hardens, shrinks and splits after some years.
Most people get in touch when they notice something like this:
- Water running down the wall below the gutter
- Stop ends leaking at the end of a run
- Damp on an inside wall under a dripping gutter
- Failed sealant on a garage door frame
For an older house near a landmark such as St Francis' Church, older walls, gutters and the joints where extensions meet them need a flexible sealant.

Landlords, agents and businesses in Hilsea
Whether it’s one flat or a portfolio, the work is the same standard: old sealant fully removed, joints prepared properly and a one-year guarantee.
Housing providers, facilities teams and property managers book us too in Hilsea and across Portsmouth. Several sites can go on one quote, and we are fully insured.
Should I try it myself first?
If you’ve already had a go yourself, that is fine. We remove it and do the joint properly, so just mention it when you contact us.
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
Hilsea: your questions answered
Is Hilsea within the area you cover?
Yes, we do. We work across London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
Does living near the coast affect gutter sealing in Hilsea?
Coastal weather is harder on outside sealant: there’s more wind-driven rain and, closer to the shore, salt in the air. The right product, a clean joint and the right depth all help it cope.
What does gutter sealing cost?
There’s no set price, as it depends on the job: its size, the old material, access and the product needed. We agree the price before any work begins.
Will sealing fix a sagging gutter?
No. A sagging gutter pulls its joints apart so it needs refixing before sealing.
Are you an approved applicator?
Yes. We’re an ARBOMaster approved applicator, which is run for the Arbo sealant brand.
Do you offer different sealant colours?
Most of the time, yes. We will explain which colours are available.
Are you fully insured?
Yes. Full insurance covers our work, and we can confirm the details when we quote.
Will the old sealant be removed?
Yes, always, and completely. New silicone does not stick to old silicone, so any old material comes out before anything new goes in.
Gutter sealing in Hilsea: local notes
Hilsea is close to the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. Both are hard on gutter, fascia and roofline joints, which can dry out and crack sooner where a building faces the weather. Rainfall in the South East is lower than in much of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
If you look after a building such as Gatcombe Park Primary School, movement joints, cladding joints and gutters on larger buildings need the same care as a house’s. For landlords with property near Hilsea station, a gutter joint that drips onto the wall can turn into a damp complaint, so it’s worth checking.

Looking after it afterwards
Joint life depends on how it’s used and looked after. Here’s what we suggest:
- Deal with a drip before winter
- Get a dropping gutter looked at quickly
- Glance at the soffit joints now and then
- Keep ladders off the guttering
Keep downpipes clear so the gutter can drain. Blockages push water back along the gutter.
A leaking stop end is best sealed before the wet months. A winter of drips can lead to damp patches.
