External Mastic in Tilford
Sealing brickwork movement joints, render, cladding and façade joints for homeowners, landlords and businesses in Tilford. Fully insured, ARBOMaster approved and guaranteed for a year.
- Old sealant gone brittle and cracked
- Leaking joints around cladding and façade panels
- Weeds or debris growing in open joints
Why deal with it now?
Pointing a movement joint with mortar might seem a neat fix, but it locks the joint solid. The wall then cracks somewhere else. The correct repair is a flexible sealant with the right backing. Around Tilford, older homes often have timber in their 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 us?
- A choice of colours where the product allows
- You choose the colour before work begins
- A 12-month guarantee on all work
- Neat joints and a tidy finish

External mastic for homes and businesses in Tilford
Short cuts in external joints show up within a season or two. New sealant over old, joints packed with mortar and beads with no backing all tend to fail early. We strip the joint back and start again. Common call-outs are for moss and dirt in joints with no sealant left and joints where the bead has come unstuck, on joints between brick and frames, copings & trims and concrete & block.
External sealant needs dry, clean surfaces, so work around Tilford is planned for dry weather. Tell us about access to all sides of the building, including outbuildings and garages.
You get a 12-month guarantee, the same in Tilford as everywhere else we work.

Walls and rooflines in Tilford
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. With historic houses such as Farnham Castle (about 3.2 miles north-west) nearby, there’s older building stock in the area around Tilford as well as newer homes. Where a home is older, older brick and stone need a sealant that suits them, at the right joint depth.
If you let a flat or house near Farnham station, failed wall and movement joints let damp in, so they’re worth checking between tenancies. If you live in an older home near Church of All Saints, older walls, gutters and the joints where extensions meet them need a flexible sealant.
Tilford is about 3 miles south-east of Farnham, in Surrey. Homes, rented property, offices and hotels in Tilford can book us for external mastic. Every job comes with our 12-month guarantee.

How the job changes by surface
Concrete and blockwork
The face of concrete or block is often dusty, so preparation is key. We prime where the sealant needs it before sealing.
Render joints
Water behind render can lead to blown patches. A sound joint keeps the render dry behind.
What we’re called out for in Tilford
The wrong product in a moving joint is a classic cause. A high-modulus or general-purpose sealant can be too rigid for a busy joint, so it pulls away from the edges.
These are the problems we’re asked about most:
- Cracked joints where brick meets render or frames
- Plants rooting in failed movement joints
- Old sealant gone brittle and cracked
- Rigid filler in a joint that should flex
For site and facilities teams at buildings such as Waverley Abbey CofE Junior School, its movement joints, gutters and trims need looking after like any other building’s.

Tilford questions
Do you cover Tilford for external mastic?
Yes. Our work covers London and the South East, and Tilford is part of that. Just phone 0345 464 0079 or drop us an email with a few details of the job.
Is Tilford within the area you cover?
Yes, we do. Our work covers London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
What is backing rod for?
The foam is closed-cell backing rod. It stops the sealant going in too deep and bonding to three sides, which would stop it stretching.
What does external mastic cost?
We do not publish prices, because the cost depends on the job: its size, the old material, access and the product needed. We agree the price before any work begins.
Where do you work from?
We are based in Crawley, West Sussex, and we cover South East England, London and all of Scotland.
Will there be a smell?
There can be a smell while the sealant cures, but it fades. Ventilation helps.
Will the new joint stand out?
We aim for a joint that suits the wall rather than one that jumps out. Colour is agreed with you before we begin.
Should I point up the gap in my brickwork?
No. Cement or mortar cannot stretch. Where a joint has been mortared, it can often be raked out and sealed properly.
Looking after it afterwards
No joint lasts for ever, but care makes a real difference. Our tips:
- Wash walls gently around the sealant
- Point out the joints to other trades
- Clear growth from the base of walls and joints
- Check the sealant is paintable before painting near it
Make sure anyone working on the wall later knows where the movement joints are. They must stay as flexible joints, never rendered or pointed over.
A joint that has stopped moving pushes the movement elsewhere, usually as cracking in the brickwork or render nearby. Resealing it early helps prevent that.
How it works
We bring everything the job needs with us. Once we have agreed what’s being done, the area is protected and the work begins. It normally takes a few hours to a few days, depending on the length of joint and the access. For a village or hamlet like Tilford, the journey is planned in advance: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.
- First, the joints are inspected and the access agreed.
- 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.
How to prepare
- Mention any tricky access
- Mention any sign-in or site rules at work premises

Advice
DIY sealant or a professional job?
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, then guaranteed for a year.
Sealing over old silicone is the commonest DIY error. Silicone doesn’t stick to old silicone, so it lifts and traps water and mould underneath. All the old material has to come out first.
