Your questions about external mastic in East Shefford
Is East Shefford in your area for external mastic?
Yes, East Shefford is within the area we cover. We work across London and the South East. You can call 0345 464 0079 or email us and let us know what needs doing.
Can you help a landlord with a rental near Kintbury station?
Yes, we work for letting agents and landlords. Just ring 0345 464 0079 or send us an email and tell us about the property, and we’ll give you a clear quote.
What do you put in the joint?
Products from Arbo and Everbuild, among others, chosen to suit the joint. We explain the product when we quote.
Are you ARBOMaster approved?
Yes. We are an ARBOMaster approved applicator, the approved applicator scheme for Arbo sealants.
When is the sealant fully cured?
Different products cure at different speeds, so please follow the time we give you.
Can you seal over the old sealant?
No. Fresh sealant does not stick to old sealant, and anything trapped underneath, including mould and water, stays there. We remove it all first.
How much does external mastic cost in East Shefford?
The cost depends on the size of the job, access and how much old sealant has to come out. Ask us for a quote and we’ll talk you through it.

External mastic in East Shefford, done properly
Failed sealant is cut out, the depth set with closed-cell backing rod, and the joint resealed with a low-modulus sealant made for outside. The colour is chosen to suit the brick or render so the line blends in. If you have movement joints with cracked, split or missing sealant and weeds or debris growing in open joints, we can help.
Somewhere as small as East Shefford, homes and farm buildings often face open ground, so walls and rooflines take the full force of wind and rain. 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 sealant work cannot fix
New sealant cannot fix everything, and we’ll tell you before work begins. Sealant won’t put right:
- Movement that is more than a sealant joint can take
- Rising or penetrating damp from elsewhere in the wall
- Cracking across the wall rather than at a joint
If in doubt, ring 0345 464 0079 or send us an email and we’ll say what we think.
Surfaces we seal
- Façade panels
- Copings & trims
- Brickwork movement joints
- Render & cladding joints
- Concrete & block
- Joints between brick and frames
How to look after the new joints
To keep the joints looking good and working properly:
- Look over the joints every year, ideally after winter
- Check the sealant is paintable before painting near it
- Have failed joints looked at early
- Clear growth from the base of walls and joints
If you have more work done on the wall, such as new render, cladding or an opening, show the contractor the movement joints. They must stay as flexible joints, never rendered or pointed over.
Water getting behind cladding or render can go unnoticed for a long time. When it finally shows inside, the joint may have been open for years.

Failed sealant is one of the commonest items on a check-out report, and it’s quick to put right between tenancies. We can quote for more than one property at once.
What we do, step by step
A visit follows a simple pattern: we look at the joints together, protect the area around them, carry out the job and clear up. It usually takes a few hours to a few days, depending on the length of joint and the access. In a small place like East Shefford, access is usually the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- 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
- Tell us about access, such as stairs, a lift or high-level joints
- For business premises, tell us about site rules or sign-in
- Clear the area around the work

Walls and rooflines in East Shefford
Rainfall in the South East is lower than in much of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
For site and facilities teams at buildings such as Shefford C.E. Primary School, its movement joints, gutters and trims need looking after like any other building’s. If you live in an older home near St Thomas' Church, an extension built onto an older house moves differently, and the joint between them takes the strain.

Do you need external mastic in East Shefford?
Poor preparation causes many early failures: joint faces that were dusty or damp, unprimed where they needed it, or still carrying old sealant. The new sealant then lets go long before it should.
The problems people usually mention when they call include:
- Movement joints with cracked, split or missing sealant
- Weeds or debris growing in open joints
- Sealant that has lost its bond to the brick or render
- Old sealant gone brittle and cracked
If you let a flat or house near Kintbury station, split movement joints are easy to miss on a rental until damp shows inside.
What to look for in a quote
- How much experience the applicator has
- Whether VAT is included
- Whether you can choose the colour
- Whether the sealant suits the joint

Render joints
The face of render can be soft, so a low-modulus sealant is kinder to the joint edges. Priming is done where the sealant calls for it.
Copings and trims
Joints in copings, parapets and trims are exposed to the worst of the weather. Each is resealed with a weatherproof, flexible sealant.
