External & façade joints in Lower Bourne, Surrey
Sealing brickwork movement joints, render, cladding and façade joints for homeowners, landlords and businesses in Lower Bourne. ARBOMaster approved applicators, fully insured, with a 12-month guarantee.
- Gaps where render, brick and frames meet
- Movement joints filled with mortar instead of sealant
- Movement joints with cracked, split or missing sealant
Surface by surface
Render joints
The face of render can be soft, so a sealant that stretches easily protects the edges. Priming is done where the sealant calls for it.
Cladding and façade panels
Metal and composite panels move a lot with temperature, so the joints work hard every day. We choose the product to suit.
External mastic in Lower Bourne, done properly
Joints between dissimilar materials, like brick against render or concrete against a steel frame, see movement from both sides. A flexible sealant bridges the two where a rigid filler would soon crack. If you’re dealing with weathered mastic that no longer stretches and moss and dirt in joints with no sealant left, we can help, on joints between brick and frames, concrete & block and render & cladding joints alike.
In a smaller place like Lower Bourne, some homes face open ground, so exposed walls and rooflines take more wind-driven rain. Joints on those sides are usually the first to go.
We guarantee the work for a year. If there’s a problem with our work within the year, let us know and we’ll sort it.

Outside joints around Lower Bourne
With historic houses such as Farnham Castle (about 1.6 miles north) nearby, there’s older building stock in the area around Lower Bourne 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. The South East is one of the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
Rented homes near Farnham station change hands often, and failed wall and movement joints let damp in, so they’re worth checking between tenancies. Homes close to St Martin by the Green include some older properties, and an extension built onto an older house moves differently, and the joint between them takes the strain. For site and facilities teams at buildings such as Farnham College, movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.

- Render that is blown, hollow or coming away
- Rising or penetrating damp from elsewhere in the wall

Questions from Lower Bourne
Is Lower Bourne within the area you cover?
Yes, smaller places are covered as well as towns. Our work covers London and the South East. Just mention lanes, gates or anything else about the route when you book.
Is Lower Bourne in your area for external mastic?
Yes, Lower Bourne is within the area we cover. Our work covers London and the South East. Just phone 0345 464 0079 or email us with a few details of the job, and we will send you a clear quote.
Will it make a mess?
No. We work neatly, protect the area around the joints and tidy up afterwards.
Can you work on commercial sites?
Yes. Hotels, offices and other businesses use us, and we’re fully insured.
Why do you put foam in the joint first?
That is backing rod, a closed-cell foam. It keeps the sealant at the right depth and bonded to the sides only, which would stop it stretching.
Can I do it myself?
Some simple jobs can be done by a careful DIYer. The usual mistakes are sealing over old sealant, sealing a damp joint and using too much.
Are you ARBOMaster approved?
Yes. We hold ARBOMaster approved applicator status and we are fully insured too.
Is there any odour?
Some sealants have a smell while they cure. Ventilation helps.
DIY versus a professional finish
If you’re set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it does not work out, we can still put it right.
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
What affects the quote in Lower Bourne
For a quick quote, just ask. What matters most is:
- How much old sealant there is and how hard it is to remove
- The product the joint needs
- How many rooms, windows or areas are involved
- Access and height
Homes and businesses are quoted the same way: the amount of work, the access and the products needed, along with when we can work on site. Ask us for a quote and we’ll explain what it covers.
What we need to know
To make quoting easier, please include:
- If it’s domestic, commercial or a hotel
- Where the job is, and your postcode
- Photos by email, if that is easy
- The rough size of the job
Call for a quick quote, or send an email if you’d rather. Describe what needs sealing and we will talk you through the work before giving you a price.
Leave it or put it right?
Low-modulus sealants stretch easily, so they put less strain on the joint edges. That matters on brick, render and concrete, which can be weaker at the face. Too stiff a sealant can pull at the edges and break them. In a smaller place like Lower Bourne, 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.
A failed joint rarely gets cheaper to fix by waiting, because water and mould keep working on it. If you’re unsure, phone 0345 464 0079 or drop us an email for an honest opinion and a quote.

What we do, step by step
Every visit runs the same way: we look at the joints together, protect the area around them, do the work and clear up. It normally takes a few hours for a handful of joints, longer for a whole elevation. Parking around Lower Bourne is usually easier than in a town centre, but mention any lanes, gates or long drives. If the job is outside, tell us about side access and how high the joints are.
- 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.
- Backing rod sized to the joint goes in to set the depth.
- The exterior sealant is applied, tooled and checked along its length.
How to prepare
- Mention if the joints have been sealed before
- On commercial sites, let us know about site rules
- Let us know about stairs, lifts or work at height
