External & façade joints in Fair Oak, Hampshire
Sealing brickwork movement joints, render, cladding and façade joints for householders, landlords and businesses in Fair Oak. ARBOMaster approved applicators, fully insured, with a 12-month guarantee.
- Failed seals between different materials
- Sealant pulling away from one side of the joint
- Plants rooting in failed movement joints
Keeping the joints in good condition
How long the joints last depends on use and care. We suggest:
- Ask before painting over external sealant
- Get split or bare joints resealed while the damage is small
- Make sure movement joints are not pointed over
- Point out the joints to other trades
Give the sealant the cure time we tell you before anything rubs against it. The surface skins over quickly, but full cure takes longer.
Act while the splits are small. Then it’s a straightforward cut-out and reseal.
External mastic in Fair Oak
We cut out failed sealant, set the joint depth with closed-cell backing rod and reseal with a low-modulus exterior sealant. We pick a colour that sits well with the wall so the joint does not stand out. If you are dealing with gaps where render, brick and frames meet and joints where the bead has come unstuck, we can put it right, on façade panels, render & cladding joints and copings & trims alike.
Houses in smaller places like Fair Oak can stand more in the open than those in a built-up town, and walls and rooflines facing the weather take the worst of it. That is where gutter joints and wall joints tend to fail first.
All of our work is guaranteed for twelve months.

What happens on the day
A visit follows a simple pattern: we look at the joints together, mask and protect the surrounding surfaces, carry out the job and clear up. Most jobs take a few hours to a few days, depending on the length of joint and the access. Parking around Fair Oak is generally easier than in a town centre, but mention any lanes, gates or long drives. For outside work, side access and the height of the joints help us plan.
- 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.
- Joint faces are cleaned back and primed if the sealant needs it.
- We fit closed-cell backing rod to control the depth.
- We apply the sealant, tool it and check the whole run.
Preparing for the visit
- Move anything stored near the joints
- Mention any sign-in or site rules at work premises
- Mention any parking rules near the property

Advice
When something else is needed
New sealant can’t fix everything, and we’d rather say so up front. It won’t solve:
- Subsidence or other structural problems
- Rising or penetrating damp from elsewhere in the wall
- Cutting new joints into brickwork, which is building work rather than sealant work
If in doubt, phone 0345 464 0079 or send us an email and we will say what we think before booking.
What we seal
- Render & cladding joints
- Brickwork movement joints
- Copings & trims
- Façade panels

- Concrete & block
What affects the cost of external mastic
We quote each job individually. These are the things that affect it:
- Any mould that needs treating
- The product the joint needs
- How many rooms, windows or areas are involved
- The number and length of the joints
What you pay reflects the work, not a rough estimate. That’s why we ask a few questions first and give you a clear price before we start.
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:
- Roughly how big the job is
- Whether it has been sealed before
- If it’s domestic, commercial or a hotel
- The problem you’ve noticed
Every job is quoted individually, so the first step is telling us about yours. Just phone 0345 464 0079 or email us with the details, and pictures are welcome.

What external mastic looks like in Fair Oak
With historic houses such as South Stoneham House (about 3.9 miles south-west) nearby, there’s older building stock in the area around Fair Oak as well as newer homes. Where a home is older, older walls and rooflines need a sealant that moves with them and suits the material. London and the South East are among the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
For site and facilities teams at buildings such as Fair Oak Junior School, its movement joints, gutters and trims need looking after like any other building’s. For an older house near a landmark such as Saint Thomas, an extension built onto an older house moves differently, and the joint between them takes the strain.

FAQs for Fair Oak
I let a flat near Hedge End station. Can you help?
Yes, rental work is part of what we do. Just phone 0345 464 0079 or email us and tell us about the property, and we will give you a clear quote.
Do you cover smaller places like Fair Oak?
Yes. Fair Oak is within the area we cover, which takes in towns, villages and rural addresses. We work across London and the South East. Just mention lanes, gates or anything else about the route when you book.
Do you guarantee your work?
Yes: twelve months. If anything isn’t right with the work within the year, let us know and we’ll sort it.
Will you leave a mess?
We keep the work tidy. We protect what’s around the joints, and we clear up when we’re done.
How long should I leave it?
Many sealants skin over quickly but take longer to cure fully. We will give you the cure time for the product we used.
Do you have insurance?
Yes. Full insurance covers our work, and we can confirm the details when we quote.
Can you seal over the old sealant?
No. Fresh sealant does not stick to old sealant, and it traps any mould or water underneath. We remove it all first.
How long will you be here?
As a guide, most jobs take a few hours to a few days, depending on the length of joint and the access. Bigger jobs take longer, and we’ll tell you how long to expect.
Why act early in Fair Oak
A properly done movement joint is an even line in a colour that suits the wall. A hurried job with smeared edges and no backing looks worse and fails sooner, so it pays to do it properly once. In a smaller place like Fair Oak, wherever a wall is exposed, a failed outside joint is a real source of damp. Inside, a split seal lets water into floors and panels just as it would anywhere.
What it costs depends on the size of the job, how hard the old material is to remove and how easy the joints are to reach. You will have a clear quote before any work starts, so you know where you stand.

Signs you need external mastic in Fair Oak
The wrong product in a moving joint is a classic cause. A stiff, general-purpose sealant cannot cope with a joint that moves a lot, so it pulls away from the edges.
These are the problems we are asked about most:
- Water getting into walls through failed joints
- Weathered mastic that no longer stretches
- Brick movement joints where the sealant has split
- Failed seals between different materials
For landlords with property near Hedge End station, outside joints that have cracked can let damp into a rental, so check them between lets.

DIY sealant or a professional job?
A DIY attempt does not rule out a professional job. We remove it and do the joint properly, so tell us about it when you ask for a quote.
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions, and the work is guaranteed for a year.
