What gutter sealing looks like in Portsmouth
Portsmouth is within about 1 mile of the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. That is hard on gutter, fascia and roofline joints, especially on the side facing the sea. 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 live in an older home near St Wilfrid, old and new materials meet at the roofline and walls, which is where sealant earns its keep. Letting a property close to Fratton station? Then leaking gutter joints on a rental are best caught before they stain the walls.

Gutter sealing for homes and businesses in Portsmouth
Garage door frames let rain in when the sealant around them fails. The frame joint is cut out and resealed using a sealant made for outdoor use. We are often asked to deal with drips from gutter joints and end caps and old gutter sealant that has let go, across uPVC fascias, roofline trims and gutter end caps.
Portsmouth has everything from period brickwork to modern rendered and clad buildings. Modern walls depend on their movement joints; older houses depend on sound gutter and roofline joints.
We guarantee the work for a year. If something is not right with it in that time, tell us and we’ll put it right.

Do you need gutter sealing in Portsmouth?
Water spilling over a blocked gutter is often mistaken for a leak. If the downpipe is blocked, water has nowhere to go, which is why we look before we seal.
The most common problems we see are:
- Leaking gutter joints and stop ends
- Cracked sealant along roofline trims
- Internal damp traced to a gutter joint
- Old gutter sealant that has let go
For site and facilities teams at buildings such as Manor Infant School, larger buildings have long runs of movement joint that eventually need resealing.

Different surfaces, different methods
Gutter joints
Most gutter leaks start at a joint between sections. We clean, dry and reseal them.
Soffit joints
We choose a sealant colour that suits the soffit, where one is available.
Aftercare tips
How long the joints last depends on use and care. We suggest:
- Have sagging gutters refixed early
- Keep ladders off the guttering
- Glance at the soffit joints now and then
- Look for streaks or damp on the wall below gutters
Look at fascia and trim joints when you’re checking the gutters. A small split is quicker to put right.
Rain getting in round a garage door frame can damage what’s stored inside. Resealing the frame is a quick job.
What we can’t put right
We’d rather tell you now than do work that will not last, so here’s what sealant can’t put right:
- Rotten or damaged fascia boards
- Roof leaks, slipped tiles or failed flashing (a roofer’s job)
- Gutters that have dropped or pulled away
If in doubt, ring 0345 464 0079 or email us and we will say what we think before booking.
Joints and surfaces we work on

Can I do it myself?
If you’ve already had a go yourself, that’s fine. We cut it out and start again, so tell us about it when you ask for a quote.
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
Portsmouth: your questions answered
Can you do gutter sealing in Portsmouth?
Yes, Portsmouth is within the area we cover. Our work covers London and the South East. You can call 0345 464 0079 or email us and let us know what needs doing.
Does living near the coast affect gutter sealing in Portsmouth?
Coastal homes put outside sealant through more weather than inland ones, so the choice of sealant and the preparation matter even more. Walls facing the sea are generally the first to need attention.
Is it OK to seal over old sealant?
No. New silicone will not bond to old silicone, and anything trapped underneath, including mould and water, stays there. It all has to come out first.
Can you work on commercial sites?
Yes. Hotels, offices and other businesses use us, and we are fully insured.
Will the old sealant be removed?
Yes. All of the old material is cut out and the joint cleaned before resealing.
Will it make a mess?
No. We protect the surfaces around the joints, and we clear up the old sealant and our materials before we leave.
Are you an approved applicator?
Yes. We’re ARBOMaster approved, the scheme for applicators of Arbo sealants.
Do you clean gutters?
We clear what’s around the joints we work on. Full gutter cleaning is a separate job.
The process
A visit follows a simple pattern: we look at the joints together, mask and protect the surrounding surfaces, do the work and tidy away. It normally takes a few hours, depending on the number of joints and the access. In central Portsmouth, parking can be tight, so tell us about driveways, permits or nearby car parks. For flats, mention stairs, lifts and shared entrances as well.
- We start by tracing the leak and checking the gutter itself is sound.
- Old sealant and dirt are removed from the joint.
- The joint is dried, because sealant will not bond to a wet surface.
- We seal the joint with a sealant made for gutters and outdoor use.
- We check the run and clear any debris we find while we’re there.
Before we arrive
- Move anything stored near the joints
- Let us know about earlier repairs to the joints
- Mention any parking rules near the property

Why it’s worth doing now in Portsmouth
A new garage door is not needed for a leaking frame. Sealing the frame usually stops it, if the frame itself is sound. For landlords in Portsmouth, failed sealant soon turns into tenant complaints about mould, damp or draughts. Sorting it between tenancies is easier than dealing with it mid-let.
A failed joint rarely gets cheaper to fix by waiting. If you’re not sure whether it needs doing, call 0345 464 0079 or drop us an email for an honest opinion and a quote.
