We cover Forest Side for sealing brickwork movement joints, render, cladding and façade joints. Old sealant removed completely, joints prepared properly and a 12-month guarantee.

The process
There isn’t much for you to do on the day. Point us to the joints and we will get on with it. The work itself takes a few hours for a handful of joints, longer for a whole elevation. For a village or hamlet like Forest Side, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.
- We start by walking round the building and agreeing the joints and the access.
- Every bit of old sealant and any mortar or debris is cut out.
- The faces are brushed clean and primed where the product requires it.
- We fit closed-cell backing rod to control the depth.
- The exterior sealant is applied, tooled and checked along its length.
Before we arrive
- Mention any leaks or damp you’ve noticed
- Tell us if parking is tricky
- Clear items away from the joints we’re working on

It all starts with a short chat. Describe the problem, the location and the size of the job, and we will explain how we’d tackle it. When it suits you, ring 0345 464 0079 or send us an email.
Advice
External mastic in Forest Side, done properly
Joints in render and cladding are easy to overlook until a damp patch appears. We look over the joints, agree the ones to renew and reseal with a flexible, weatherproof product in a colour to suit. We work on joints between brick and frames, brickwork movement joints and façade panels, and common reasons people get in touch are movement joints filled with mortar instead of sealant and gaps where render, brick and frames meet.
In a village or hamlet like Forest Side, older cottages and farm buildings often stand in the open, where walls and rooflines take the weather head on. Gutter joints and wall joints there need a sealant that can flex and stay put.
Each job carries a 12-month guarantee, large or small.

What else we do in Forest Side
Signs you need external mastic in Forest Side
Every building moves. Brickwork grows a little over the years, blockwork and concrete shrink, and all of it moves with heat and moisture. All of that ends up in the joint sealant.
Common reasons people contact us are:
- Sealant that has lost its bond to the brick or render
- Hard, crazed mastic that has stopped moving
- Weeds or debris growing in open joints
- Leaking joints around cladding and façade panels
In the older streets around St. Mary's Church, older walls, gutters and the joints where extensions meet them need a flexible sealant.

Can I do it myself?
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.
If you’re set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.
When it isn’t the sealant
We’ll always be straight with you, so here’s what sealant cannot fix:
- Render that’s blown, hollow or coming away
- Cutting new joints into brickwork, which is building work rather than sealant work
- Subsidence or other structural problems
If in doubt, phone 0345 464 0079 or drop us an email and we’ll say what we think.
What we seal
- Façade panels
- Render & cladding joints

- Copings & trims
Surface by surface
Brickwork movement joints
Vertical joints in long brick walls let the brickwork expand without cracking. They’re resealed over backing rod with a low-modulus sealant in a colour to suit the brick.
Cladding and façade panels
Where a cladding system has its own specified sealant, we follow it, or one the system allows. Tell us what the building has when you get in touch.

Your questions about external mastic in Forest Side
Is external mastic in Forest Side guaranteed?
All our work, in Forest Side and everywhere else, comes with a 12-month guarantee. We are fully insured, and an ARBOMaster approved applicator.
Is Forest Side in your area for external mastic?
Yes. Our work covers London and the South East, and Forest Side is part of that. Just ring 0345 464 0079 or email us with a few details of the job.
Do you work for landlords and businesses?
Yes. Domestic, commercial and hotel work are all part of what we do, and we are fully insured.
How long does external mastic take?
It depends on the size of the job, but as a guide it takes anything from a few hours to several days, depending on the building. We’ll give you a better idea when we quote.
Are you fully insured?
Yes. Mr Mastic is fully insured, with over 20 years’ experience in sealant work.
What do you put in the joint?
The product depends on the job: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. Brands we use include Arbo and Everbuild.
Why do you put foam in the joint first?
Backing rod controls the sealant depth and keeps it off the back of the joint. That way it bonds to the two sides only and can stretch.
I’m a tenant. Can you help?
Yes, but check with your landlord or agent first. Many landlords are glad to have it sorted.
Why act early in Forest Side
Running new sealant over the old bead rarely lasts. New sealant does not bond well to old, weathered sealant, so we always take the old sealant out. Older cottages and farmhouses around Forest Side can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
Rather than a set price list, we look at what your job involves: how many joints, what’s in them now and how we reach them. You will know the price before we begin.
Why Forest Side customers choose us
- 20+ years of sealant experience
- Any old sealant cut out fully, not covered over
- Tidy, careful work
- A sealant colour to suit the surroundings

External mastic in Forest Side: local notes
With historic houses such as Carisbrooke Castle (about 1.3 miles south) nearby, there’s older building stock in the area around Forest Side as well as newer homes. In older buildings, older brick and stone need a sealant that suits them, at the right joint depth. Compared with the north and west, the South East gets less rain, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
If you look after a building such as Carisbrooke College, larger buildings have long runs of movement joint that eventually need resealing.
