About our external mastic in Furzeley Corner
We cut out failed sealant, set the joint depth with closed-cell backing rod and reseal with a low-modulus exterior sealant. The colour is chosen to suit the brick or render. We are often asked to deal with damp patches traced to an open external joint and panel joints letting water in, across render & cladding joints, copings & trims and façade panels.
In a village or hamlet like Furzeley Corner, older cottages and farm buildings often stand in the open, so walls and rooflines take the full force of wind and rain. Gutter joints and wall joints there need a sealant that can flex and stay put.
Big or small, you get the same one-year guarantee.

Furzeley Corner buildings and the weather
Furzeley Corner 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 movement joints and outside wall joints, especially on the side facing the sea. Rainfall in the South East is lower than in much 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 Denmead Junior School, movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.
Furzeley Corner is about 1 mile west of Waterlooville, in Hampshire.

Furzeley Corner questions
Can you help a landlord with a rental near Cosham station?
Yes. We work for landlords and letting agents as well as homeowners. Just ring 0345 464 0079 or email us with the address and what needs doing, and we’ll give you a clear quote.
Does the coastal weather in Furzeley Corner affect outside sealant?
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.
Are you an approved applicator?
Yes. We’re ARBOMaster approved, the scheme for applicators of Arbo sealants.
Do you have insurance?
Yes, we’re fully insured for domestic and commercial work.
What do you need from me for a quote?
The location, the problem and the rough size of the job. If you can, email a few pictures.
Can I do it myself?
For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. Most DIY failures come from sealing over old material, wet joints or too much sealant.
Where is Mr Mastic based?
Mr Mastic is based in Crawley. We cover Furzeley Corner and the rest of Hampshire, along with the rest of our area.
Can you reach joints on upper floors?
That depends on the building and the joints. We work on joints that can be reached safely. Tell us about the building and we will confirm what access is needed.

Looking after it afterwards
Looking after new joints is easy, and it makes a real difference:
- Act on the first splits you see
- Deal with leaking gutters that soak the joints below
- Keep soil, plants and ivy away from the joints
- Check external joints each spring
Keep the joints clear of soil, plants and climbing growth. Anything that holds water against the joint wears it out sooner.
Gaps, plants or missing sealant in a joint are worth getting looked at. Earlier resealing means a smaller job and a better result.
The process
We keep the work tidy and contained to the area we are working on. The job generally takes a few hours for a handful of joints, longer for a whole elevation, and we tell you how long to leave it before we go. Somewhere as small as Furzeley Corner, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- Each joint is checked and the colour of the new sealant agreed.
- We take out the old sealant until the faces are sound.
- Closed-cell backing rod is pushed in so the sealant bonds to two sides only.
- We prime the faces where required.
- We gun in low-modulus sealant and tool it neatly.
How to prepare
- Try not to wet indoor joints just before the visit
- Let us know about stairs, lifts or work at height
- Tell us about any previous sealing or DIY attempts

Do you need external mastic in Furzeley Corner?
Buildings move more than people expect. Clay bricks expand slightly over their life, concrete and block shrink, and everything moves with temperature and wet. All of that ends up in the joint sealant.
Signs it’s time to call us include:
- Movement joints filled with mortar instead of sealant
- Hard, crazed mastic that has stopped moving
- Gaps where render, brick and frames meet
- Plants rooting in failed movement joints
For landlords with property near Cosham station, split movement joints are easy to miss on a rental until damp shows inside.

What the job involves on each surface
Cladding and façade panels
Panel systems often rely on sealant between and around the panels. We reseal them with a sealant suited to the panel material.
Render joints
Rendered walls have joints at beads, openings and changes of material. They’re resealed in a sealant that suits the render.
DIY sealant or a professional job?
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 does not work out, we can still put it right.
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
