Gutter sealing in Hampshire: how it works

Across Hampshire, we reseal gutter joints, end caps and roofline trims. Single-storey and low gutters are simple to reach and if it’s higher up, let us know and we will confirm what access is needed. Typical jobs include water dripping where gutter sections meet and damp on an inside wall under a dripping gutter, on roofline trims, gutter end caps and uPVC fascias.

The work is kept neat and contained to the joints we are treating, so you can get on with your day. The job normally takes a few hours, depending on the number of joints and the access, and we explain the cure time before we leave.

We look at the gutters, fascias and trims and agree the joints to seal.
Each joint is cleaned and any old sealant removed.
We make sure everything is dry.
We apply exterior or gutter sealant and finish it neatly.
The joints are checked once sealed.

What you’ll pay

The cost depends on the size of the job, 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.

Outside joints across Hampshire

Hampshire has everything from period brickwork to rendered and clad modern buildings. Where two materials meet is where water usually gets in.

London and the South East are among the drier parts of the UK, though outside sealant still needs a dry, clean joint, so work across Hampshire is planned around the weather. In the coastal parts of Hampshire, the sea-facing side of a building takes the most weather, and that is where sealant usually gives up first. Good preparation and the right sealant help it cope.

Basingstoke: For site and facilities teams at buildings such as King's Furlong Infant School and Nursery, larger buildings have long runs of movement joint that eventually need resealing. For an older house near a landmark such as St Michael's Church, older walls, gutters and the joints where extensions meet them need a flexible sealant.

When it is not the sealant

A few problems are outside what sealant work can do:

Sagging gutters or broken brackets
Roof leaks, slipped tiles or failed flashing (a roofer’s job)
A gutter length that has split

Why act early?

Replacing fascias because of open joints is generally unnecessary. Sealing the joints tidies them up if the boards are sound.

Questions to ask before booking

What happens if they find a problem under the old sealant
The length of the guarantee
Who turns up on the day
Whether VAT is included

Should I try it myself first?

Sealing over old silicone is the commonest DIY error. Silicone does not stick to old silicone, so it peels away and traps moisture behind it. All the old material has to come out first.

Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.

How the job changes by surface

Soffit joints

Open soffit joints let draughts in. A neat seal closes them.

uPVC fascias

Our work is the joints, not new fascias. If boards are damaged, we’ll tell you.

Signs you need gutter sealing

Roofline sealant ages in sun and rain. It goes hard, cracks and pulls away over time.

Keep an eye out for these signs:

Stop ends leaking at the end of a run
Wet patches on the wall under a gutter joint
Open joints in fascias and soffits
Rain getting in around a garage door

Hampshire: your questions answered

I rent my home. Can I book you?

Yes, though it’s best to check with your landlord first. Landlords are often happy for the work to be arranged.

How long should I leave it?

Different products cure at different speeds, so follow the cure time we give you.

Can sealant stop a sagging gutter leaking?

Not for long. The joint will pull apart, so the fall and brackets need sorting first.

Where is Mr Mastic based?

We’re based in Crawley, West Sussex, and we cover South East England, London and all of Scotland.

Do you do commercial work?

Yes. We can plan bigger jobs in stages to suit the site.

Can landlords and businesses book you?

Yes. We work in homes, commercial premises and hotels, and we’re fully insured.
