External mastic in Wooburn Common, done properly
Short cuts in external joints show up within a season or two. New sealant over old, joints packed with mortar and beads with no backing all tend to fail early. We strip the joint back and start again. If you have failed seals between different materials and hard, crazed mastic that has stopped moving, we can help.
Outside joints can only be sealed when they’re dry, so work in Wooburn Common is booked around the forecast. Tell us about access to all sides of the building, including outbuildings and garages.
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.

What external mastic looks like in Wooburn Common
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. Historic houses like Cliveden (about 1.8 miles south-west) are a reminder that the area around Wooburn Common has older buildings as well as new. In older buildings, older walls and rooflines need a sealant that moves with them and suits the material.
Managing a site like Wooburn Green Primary School? Then movement joints, cladding joints and gutters on larger buildings need the same care as a house’s. If you live in an older home near Church of St Paul, the joints between older walls, newer extensions and the roofline need a sealant that can move.

What we’re called out for in Wooburn Common
Sometimes a movement joint was filled with mortar or a rigid filler. The joint can’t move, so the wall cracks somewhere else instead.
The most common problems we see are:
- Sealant that has lost its bond to the brick or render
- Brick movement joints where the sealant has split
- Failed sealant between panels on a façade
- Failed seals between different materials
Letting a property close to Bourne End station? Then outside joints that have cracked can let damp into a rental, so check them between lets.
What your quote should include
- The length of the guarantee
- Who turns up on the day
- What product goes in the joint
- What insurance they hold
How to look after the new joints
A little care helps the new joints last. We recommend:
- Fix overflowing gutters above sealed joints
- Make sure movement joints are not pointed over
- Avoid pressure-washing directly into sealant joints
- Show decorators and builders where the movement joints are
If you have more work done on the wall, such as new render, cladding or an opening, show the contractor the movement joints. They should be kept open and resealed, not filled.
A joint that has stopped moving pushes the movement elsewhere, often as cracks near the joint. Catch it early and you reduce the risk.
Quotes for external mastic in Wooburn Common
We quote each job individually. This is what makes a difference:
- The type of sealant required
- The size of the job
- When we can work, for business premises
- Mould in or behind the old joints
Commercial jobs are quoted on the same basis as homes: the amount of work, the access and the products needed. Ask us for a quote and we will go through it with you.
Asking for a quote

- What the problem is, such as mould, gaps, leaks or cracking

- The rough size of the job
- Where the property is
Want a quote for external mastic? Please phone 0345 464 0079 or email us with a few details. You will know what we plan to do, and what it will cost, before any work begins.
Should I try it myself first?
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
Wooburn Common questions
Do you cover smaller places like Wooburn Common?
Yes, we do. We work across London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
Can you help a landlord with a rental near Bourne End station?
Yes. We work for landlords and agents as well as homeowners, and several properties can be quoted together. You can ring 0345 464 0079 or email us with the details for a clear quote.

How long does external mastic take?
It depends on the size of the job, but as a guide it takes anything from a few hours to several days, depending on the building. We’ll give you a better idea when we quote.
Do you work at height?
That depends on the building and the joints. Where joints can be reached safely, we will do them. Tell us about the building and we’ll confirm what access is needed.
How much does external mastic cost in Wooburn Common?
It depends on the job, so we quote each one individually. To get one, call 0345 464 0079 or email us with a short description of the job.
What sealant do you use?
It depends on the joint: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. We use products from Arbo and Everbuild.
Do you remove the old sealant?
Always. Sealing over old sealant is the main reason resealing fails early, so we never do it.
Honest limits
New sealant cannot fix everything, and we’d rather say so up front. It won’t solve:
- Damp from another source, such as a leaking gutter or a bridged damp-proof course
- Cutting new joints into brickwork, which is building work rather than sealant work
- Movement that’s more than a sealant joint can take
If you are not sure, just ring 0345 464 0079 or drop us an email and we’ll give you a straight answer before you book.

- Brickwork movement joints
- Concrete & block

What the job involves on each surface
Copings and trims
Joints in copings, parapets and trims are exposed to the worst of the weather. We reseal them with an exterior sealant suited to the material.
Cladding and façade panels
Panels heat up and cool down quickly, so the joints work hard every day. We choose the product to suit.
