FAQs for Little Yeldham
Is there a guarantee on external mastic in Little Yeldham?
All our work, in Little Yeldham and everywhere else, comes with a 12-month guarantee. We are also fully insured and ARBOMaster approved.
Is Little Yeldham within the area you cover?
Yes. Little Yeldham 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.
I’m a tenant. Can you help?
Yes. Check with your landlord; we can send the quote to them too.
Do you work for landlords and businesses?
Yes. Domestic, commercial and hotel work are all part of what we do, and we’re fully insured.
Are you ARBOMaster approved?
Yes. Mr Mastic is an ARBOMaster approved applicator.
Can a movement joint be filled with mortar?
No. A mortar-filled joint cannot move, so the movement cracks the wall elsewhere. It needs a flexible sealant over backing rod.
Can you work on commercial sites?
Yes, regularly. We can plan bigger jobs in stages.
Will it make a mess?
No. We protect the surfaces around the joints, and we clear up the old sealant and our materials before we leave.
About our external mastic in Little Yeldham
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. We work on joints between brick and frames, brickwork movement joints and concrete & block, and the jobs we see most are gaps where render, brick and frames meet and weathered mastic that no longer stretches.
Outside joints can only be sealed when they’re dry, so work in Little Yeldham is booked around the forecast. Tell us about access to all sides of the building, including outbuildings and garages.
Big or small, it’s backed by our one-year guarantee in Little Yeldham and across Essex.

When to call us in Little Yeldham
A lot of failed joints come down to preparation: dusty or wet faces, no primer where one was needed, or old sealant left in. The sealant never bonds properly.
It’s worth asking for a quote if you see:
- Panel joints letting water in
- Old sealant gone brittle and cracked
- Rain getting behind render or cladding at a joint
- Sealant that has lost its bond to the brick or render
In the older streets around Parish Church of St John the Baptist, old and new materials meet at the roofline and walls, which is where sealant earns its keep.
What your quote should include
- Is the old sealant removed completely?
- How much experience the applicator has
- How long the guarantee is
- What the quote includes, VAT included or not
Keeping the joints in good condition
Once the sealant has cured, a few habits help it last:
- Keep movement joints as flexible joints, not mortar
- Check external joints each spring
- Have failed joints looked at early
- Leave the joints unpainted unless we’ve said otherwise
Don’t let soil, plants or ivy build up against the new joints. Damp material against the sealant shortens its life.
Gaps, plants or missing sealant in a joint are worth getting looked at. Earlier resealing means a smaller job and a better result.

The visit itself usually takes a few hours to a few days, depending on the length of joint and the access, depending on how much there is to do.

What external mastic looks like in Little Yeldham
Historic houses like Hedingham Castle (about 2.3 miles south) are a reminder that the area around Little Yeldham has older buildings as well as new. Where a home is older, older brick and stone need a sealant that suits them, at the right joint depth. The South East is one of the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
Around Little Yeldham, as everywhere, external mastic is only as good as the preparation behind it.

When it isn’t the sealant

DIY versus a professional finish
A DIY attempt does not rule out a professional job. We remove it and do the joint properly, so just mention it when you contact us.
The biggest DIY mistake is sealing over old sealant. Silicone doesn’t stick to old silicone, so it lifts and traps water and mould underneath. Everything old must be removed first.
Quotes for external mastic in Little Yeldham
Your quote is based on your job. We take into account:
- How much old sealant there is and how hard it is to remove
- The product the joint needs
- How much there is to do
- Any mould that needs treating
Rather than a set price list, we look at what your job involves: the amount of work, the old material and the access. The price is agreed before we begin.
Asking for a quote
You don’t need to know the technical terms. It helps if you can tell us:
- If it’s domestic, commercial or a hotel
- Roughly how big the job is
- How we’d reach the joints
- What’s wrong with the joints now
Asking for a quote is easy: tell us what needs doing and where and its rough size. A few pictures by email make the job easier to understand, and we will take it from there.
Leave it or put it right?
Resealing a run of joints in one go is normally better than patching one at a time. They’ve weathered the same way, and access only has to be arranged once. Older cottages and farmhouses around Little Yeldham can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
Combining jobs into one visit normally makes better use of the time than several visits, so it’s worth mentioning everything you’d like done. You’ll get one clear quote for the whole job.
