Barford External Mastic
Problem with your movement joints in Barford? We remove the old material, prepare the joints and seal them properly, with a 12-month guarantee.
- Gaps where render, brick and frames meet
- Joints pointed up with cement by mistake
- Water getting into walls through failed joints
Can I do it myself?
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and does not move well, and the joint depth matters as much as the 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.
About our external mastic in Barford
External mastic is a job where short cuts show quickly. New sealant over old, joints packed with mortar and beads with no backing rarely last long. We take the old material out and do it properly. Common call-outs are for moss and dirt in joints with no sealant left and failed seals between different materials, on brickwork movement joints, copings & trims and façade panels.
Somewhere as small as Barford, homes and farm buildings often face open ground, so walls and rooflines take the full force of wind and rain. Joints on those walls need a sealant that moves with the building and stays in place.
All our work is covered by a 12-month guarantee.

Work for landlords, hotels and businesses
Mouldy or split sealant often shows up at the end of a tenancy, and it’s easy to sort out between tenants. Several properties can go on one quote.
We work for landlords and letting agents as well as homeowners. Sealant work between tenants keeps a property looking cared for.
What affects the quote in Barford
We don’t publish a price list, because no two jobs are the same. The quote depends on:
- The type of sealant required
- Any mould that needs treating
- Working hours on commercial sites
- Whether old sealant or filler has to be cut out
What it costs depends on the amount of work, how hard the old material is to remove and access to the work. You’ll have a clear quote before any work starts.
Helping us quote
When you contact us, it’s useful to know:
- How many joints, rooms or windows are involved
- Access, such as stairs, a lift or height
- Where the property is

External mastic in Barford: local notes
The South East is one of the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
Homes close to St John the Evangelist include some older properties, and old and new materials meet at the roofline and walls, which is where sealant earns its keep. Letting a property close to Haslemere station? Then split movement joints are easy to miss on a rental until damp shows inside.

Do you need external mastic in Barford?
Some movement joints have been pointed up with mortar by mistake. With the joint locked solid, the movement turns into cracks elsewhere in the wall.
Common reasons people contact us include:
- Failed seals between different materials
- Damp patches traced to an open external joint
- Sealant that has lost its bond to the brick or render
- Hard, crazed mastic that has stopped moving
Schools such as St John's CofE Aided Infant School are buildings too, and larger buildings have long runs of movement joint that eventually need resealing.
Before booking anyone
- How much experience the applicator has
- Are they insured?
- How long the guarantee is
- What product goes in the joint
Keeping the joints in good condition
To keep the joints looking good and working properly:
- Check the sealant is paintable before painting near it
- Tell anyone working on the walls about the movement joints
- Fix overflowing gutters above sealed joints
- Wash walls gently around the sealant
Don’t let soil, plants or ivy build up against the new joints. Damp material against the sealant shortens its life.
If you can see gaps, plants or bare sections in a joint, have it checked. Earlier resealing means a smaller job and a better result.
What happens on the day
Once we’re on site, we compare the joints with what we discussed. If anything is different, we explain it before carrying on. Most jobs then take a few hours to a few days, depending on the length of joint and the access. For a village or hamlet like Barford, 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 inspect the joints and agree which need resealing and how they’ll be reached.
- Old sealant and any debris are cut and raked out.
- The joint faces are cleaned and primed where the sealant needs it.
- Backing rod goes in next, setting the depth and keeping the sealant off the back of the joint.
- A flexible exterior sealant is applied and tooled in a colour to suit the wall.
How to prepare
- Mention if the joints have been sealed before
- Keep pets and children clear of the area while we work
- Mention any parking rules near the property
