About our gutter sealing in Landport
A drip at a gutter joint is easy to ignore, but each shower sends water to the same place. Resealing it is a small job if the gutter is otherwise in good order. We work on soffit joints, gutter joints and garage door frames, and common reasons people get in touch are damp patches inside below a leaking gutter and gaps along fascia and soffit joints.
Homes around Landport 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.
You get a one-year guarantee, the same in Landport as everywhere else we work.

Landport: your questions answered
Can you help a landlord with a rental near Portsmouth & Southsea station?
Yes, we work for letting agents and landlords. Just phone 0345 464 0079 or drop us an email and tell us about the property, and we will give you a clear price.
Will you come out to Landport?
Yes, Landport is covered. We work across London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.
Do you do commercial work?
Yes, regularly. Larger jobs can be planned room by room or area by area.
Where is Mr Mastic based?
We’re a Crawley-based firm. Our area covers South East England, London and Scotland.
Do you clean gutters?
The joints we seal are cleaned out and clear debris we find nearby. Cleaning the whole run is a different job.
Do you replace gutters or fascias?
No. Our work is sealing joints; replacing gutters and fascias needs a gutter or roofline installer.
What sealant do you use?
It depends on the joint: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. We use products from Arbo and Everbuild.
Is there any odour?
Sometimes, a little. Any smell clears as the sealant cures.

What affects the quote in Landport
We quote each job individually. This is what makes a difference:
- Which sealant suits the joint
- The number and length of the joints
- Whether the work is at height
- How many areas need sealing
The cost reflects the work involved, not guesswork. That’s why we ask a few questions first.
What to tell us for a quote
A few details help us give you an accurate quote. When you get in contact, it helps to mention:
- How many joints, rooms or windows are involved
- A few photos by email, if you can
- The address or postcode of the job
- The type of property
If you are in Landport and need gutter sealing, phone 0345 464 0079 or email us. A short description of the job and where it is helps us quote, and you’ll get a clear quote before work begins.
Why deal with it now?
A bead squeezed onto a wet joint might hold for a while, but it soon lets go. Proper preparation is the difference. Around Landport, water from a failed joint in an older home can soak into timber and plaster, which is far harder to put right than the sealant itself.
Homes and businesses are quoted the same way: the amount of work, the access and the products needed, along with when we can work on site. Call for a quick quote and we’ll go through it with you.

- We leave the area clean and tidy
- Colour agreed with you before any work starts

DIY sealant or a professional job?
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.
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.
Landport buildings and the weather
Landport is close to the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. That is hard on gutter, fascia and roofline joints, especially on the side facing the sea. Compared with the north and west, the South East gets less rain, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
Schools such as Ark Dickens Primary Academy are buildings too, and its movement joints, gutters and trims need looking after like any other building’s. Homes close to Church of All Saints include some older properties, and the joints between older walls, newer extensions and the roofline need a sealant that can move. Rented homes near Portsmouth & Southsea station change hands often, and a gutter joint that drips onto the wall can turn into a damp complaint, so it’s worth checking.
