Gutter sealing in Inner Avenue, done properly
Gaps along uPVC fascias and soffits look untidy and can let in water and draughts. We seal them in a colour to suit where one is available. If you have streaks down the brickwork from a leaking joint and internal damp traced to a gutter joint, we can put it right, whatever the surface.
Outbuildings, garages and conservatories around homes in places like Inner Avenue add more joints to look after. Leaks usually start at a gutter end, a garage door frame or where an extension meets the house.

Why it’s worth doing now in Inner Avenue
Sealing over a dirty, wet joint is a quick fix that rarely lasts but it tends to peel off. Proper preparation is the difference. In an older home around Inner Avenue, damp from a failed joint can get into timber and plaster, and that’s a much bigger job than renewing the sealant.
Some things make a job bigger or smaller: the old material and how easily it comes out, any mould to treat, and whether the work is at height. Your quote takes all of that into account.

Should I try it myself 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.
If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it doesn’t work out, we can still put it right.
Do you need gutter sealing in Inner Avenue?
Sealant laid on a wet or dirty joint fails early. Rushed repairs often don’t last long for this reason.
Signs it’s time to call us include:
- Internal damp traced to a gutter joint
- Old sealant on roofline trims that has split
- Fascia boards with gaps between them
- Drips from gutter joints and end caps
Rented homes near St Denys station change hands often, and a gutter joint that drips onto the wall can turn into a damp complaint, so it’s worth checking.

Inner Avenue buildings and the weather
Inner Avenue is close to the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. Both are hard on gutter, fascia and roofline joints, which can dry out and crack sooner where a building faces the weather. The South East is one of the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
For site and facilities teams at buildings such as Bevois Town Primary School, movement joints, cladding joints and gutters on larger buildings need the same care as a house’s. In the older streets around Saint Mary's, older walls, gutters and the joints where extensions meet them need a flexible sealant.
Inner Avenue is about 1 mile west of Southampton, in Southampton. Across the SO14 area, our applicators can take on gutter sealing. Our Southampton coverage runs to 40 places, Inner Avenue among them.

The process
Most of a good job is in the preparation, so that is where we spend the time. Every joint is cleaned and dried before new material goes in. All told, the work takes anything from an hour or two to a few hours. For a job in Inner Avenue, we agree the time, the access and parking before the day. 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.
- We remove the old sealant and clean the joint.
- We dry the joint so the new sealant can bond.
- We seal the joint with a sealant made for gutters.
- We check the run and clear debris near the joints.
Getting ready for the visit

FAQs for Inner Avenue
Do you work for landlords with property near St Denys station?
Yes, we work for landlords and agents. Just ring 0345 464 0079 or email us and tell us about the property, and we will send you a clear quote.
Is gutter sealing in a coastal place like Inner Avenue any different?
Near the coast, wind-driven rain and, nearer the shore, salt air make outside sealant work harder. Choosing the right sealant for the frame and wall, laid at the right depth, helps it last.
What about gutters on a second or third storey?
Single-storey work is the most straightforward. We will confirm the access for higher gutters before we book.
Is it possible to stop a gutter joint dripping with sealant?
In most cases, yes. A sagging or cracked gutter needs more than sealant, and we’ll tell you.
What guarantee comes with the job?
Every job comes with our one-year guarantee, and we’re fully insured.
Where is Mr Mastic based?
Our base is in Crawley, and we work across South East England, London and Scotland.
Will the old sealant be removed?
Yes, always, and completely. New silicone does not stick to old silicone, so the joint is cleaned back first.
What do you need from me for a quote?
Just the basics: the address or postcode, what’s wrong and any access issues. After that, simply ring 0345 464 0079 or drop us an email.
