Specialist external mastic for Lydd: the right sealant, proper preparation and a neat finish. Call for a quick quote.
- Weeds or debris growing in open joints
- Damp patches traced to an open external joint
- Brick movement joints where the sealant has split
Aftercare tips
Simple care keeps the joints in good condition. We recommend:
- Deal with leaking gutters that soak the joints below
- Act on the first splits you see
- Keep movement joints as flexible joints, not mortar
- Check the sealant is paintable before painting near it
Avoid pressure-washing straight into the joints. A strong jet can damage the edges of the bead over time.
If you can see gaps, plants or bare sections in a joint, have it checked. Early work is quicker and leaves a better finish.
External mastic in Lydd
Where two different materials meet, such as brick and render or blockwork and metal, they move at different rates. A flexible sealant bridges the two where mortar or filler would crack. We work on render & cladding joints, brickwork movement joints and façade panels, and common reasons people get in touch are sealant pulling away from one side of the joint and panel joints letting water in.
Homes around Lydd range from older cottages to newer houses, with walls and rooflines of every type. Older homes need their gutter and trim joints kept tight, newer ones their movement joints.
Big or small, you get the same one-year guarantee in Lydd and across Kent.

Surface by surface
Joints between dissimilar materials
Brick against render, concrete against metal, stone against timber: every change of material is a joint. A flexible sealant bridges the two so neither cracks the other.
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.
Lydd: your questions answered
Is Lydd within the area you cover?
Yes, Lydd is covered. We work across London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
Does living near the coast affect external mastic in Lydd?
Near the coast, wind-driven rain and, nearer the shore, salt air make outside sealant work harder. The right product, a clean joint and the right depth all help it cope.
Do you seal joints where cladding meets other materials?
Yes. We cut out the old sealant, prepare both faces and reseal with a flexible exterior product. We pick a colour that works with both materials.
Can a movement joint be filled with mortar?
No. Cement or mortar cannot stretch. Where a joint has been mortared, it can often be raked out and sealed properly.
I rent my home. Can I book you?
We’re happy to deal with the tenant, landlord or agent. Get your landlord’s agreement first.
Is it messy?
No. We work neatly, protect the area around the joints and tidy up afterwards.
Are you insured?
Yes, we are fully insured.
Do you guarantee your work?
Yes. Every job comes with our one-year guarantee.
Should I try it myself first?
If you’ve already had a go yourself, that is fine. We cut it out and start again, so tell us about it when you ask for a quote.
If you’re set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it does not work out, we can still put it right.
Quotes for external mastic in Lydd
Call for a quick quote. The main things that affect it are:
- The number and length of the joints
- Which sealant suits the joint
- Working hours on commercial sites
- How many areas need sealing
Some things make a job bigger or smaller: the old material and how easily it comes out, any mould to treat, and whether we need extra access for height. We take all of that into account in your quote.
What we need to know
You don’t need to know the technical terms. It helps if you can tell us:
- Access, such as stairs, a lift or height
- If someone has resealed it before
- The address or postcode of the job
- What’s wrong with the joints now
For a quick quote, get us on the phone, or email us if that is easier. Describe what needs sealing and we will explain what’s involved before giving you a price.
What happens on the day
Once we are on site, we check the joints match what you told us. If we find something unexpected, we talk it through with you first. Most jobs then take a few hours for a handful of joints, longer for a whole elevation. A visit to Lydd is planned like any other: the time, the access and where to park are agreed in advance. If the work is outside, the weather plays a part, as sealant needs a dry surface.
- We start by walking round the building and agreeing the joints and the access.
- We cut out the old mastic and rake out anything in the joint.
- The faces are brushed clean and primed where the product requires it.
- Backing rod sized to the joint goes in to set the depth.
- We apply the sealant, tool it and check the whole run.
How to prepare
- Tell us about any previous sealing or DIY attempts
- Keep children and pets away from the work area
- For business premises, tell us about site rules or sign-in
Getting a quote
It all starts with a short chat. Describe the problem, the location and the size of the job, and we will explain how we’d tackle it. When it suits you, phone 0345 464 0079 or drop us an email.
Advice
What we’re called out for in Lydd
Sometimes a movement joint was filled with mortar or a rigid filler by mistake. With the joint locked solid, the movement turns into cracks elsewhere in the wall.
Keep an eye out for any of the following:
- Gaps where render, brick and frames meet
- Sealant pulling away from one side of the joint
- Moss and dirt in joints with no sealant left
- Brick movement joints where the sealant has split
If you look after a building such as Lydd Primary School, movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.
What to look for in a quote
- Is the old sealant removed completely?
- Is VAT in the price?
- What happens if the job turns out different
- Are they insured?
External mastic in Lydd: local notes
Lydd is close to the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. That is hard on movement joints and outside wall joints, especially on the side facing the sea. London and the South East are among the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
Homes close to All Saints Church include some older properties, and the joints between older walls, newer extensions and the roofline need a sealant that can move.
