FAQs for Moulsecoomb
Will you come out to Moulsecoomb?
Yes, Moulsecoomb is covered. We work across London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
Can you help a landlord with a rental near Moulsecoomb station?
Yes. We work for landlords and agents as well as homeowners. Just ring 0345 464 0079 or drop us an email with the address and what needs doing, and we will give you a clear price.
Can I do it myself?
It depends on the job. High-level, external movement and fire-rated joints are professional jobs, while a short indoor joint may be within reach.
Can you seal joints between render and window frames?
Yes. Where different materials meet is one of the most common joints we seal. The sealant is chosen to bond to both sides with primer where required.
Does someone need to be in?
We need access to the joints, so we’ll agree that with you when we book. Indoors, that usually means someone at home.
Is there any odour?
That depends on the sealant. Some products have a noticeable smell, others very little.
How do you reach high-level joints?
Each building is different. Send us photos and a rough idea of the height and we will confirm how they can be reached safely.
Can you quote for more than one area?
Yes. Just list everything you need and we’ll quote it together.
How we handle external mastic in Moulsecoomb
Many failed façade joints only get noticed once there’s a stain or a damp patch inside. We inspect them, agree which need doing and reseal with a weatherproof, flexible sealant in a colour to suit. If you have sealant pulling away from one side of the joint and old sealant gone brittle and cracked, we can help, on joints between brick and frames, brickwork movement joints and façade panels alike.
In and around Moulsecoomb, older properties sit alongside newer ones, each with its own outside joints. Older homes need their gutter and trim joints kept tight, newer ones their movement joints.
We stand behind the work with a 12-month guarantee.

Why act early in Moulsecoomb
The longer a joint stays open, the more water the wall takes in. In cold weather, frost can damage wet brick and render near the open joint, so the damage spreads beyond the joint. In an older home around Moulsecoomb, damp from a failed joint can get into timber and plaster, which is far harder to put right than the sealant itself.
Every job is a little different, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all make a difference, and we will explain the quote if you ask.

What we are called out for in Moulsecoomb
Weeds, moss and debris in a joint are a sign the sealant has gone. Dirt and roots then trap moisture in the joint and make things worse.
People normally contact us when they notice one of these:
- Old sealant gone brittle and cracked
- Plants rooting in failed movement joints
- Damp patches traced to an open external joint
- Gaps where render, brick and frames meet
If you look after a building such as Moulsecoomb Primary School, larger buildings have long runs of movement joint that eventually need resealing.

What else we do in Moulsecoomb
Aftercare tips
Once the sealant has cured, a few habits help it last:
- Show decorators and builders where the movement joints are
- Clear growth from the base of walls and joints
- Make sure movement joints aren’t pointed over
- Check external joints each spring
Have a quick look at the joints each spring. Splits, gaps at the edges or plants in the joint are early warning signs.
Leaks behind façade panels and render often go unseen. When it finally shows inside, the joint may have been open for years so early resealing is worth it.
How we quote for external mastic
Your quote is based on your job. We look at:
- Whether there’s mould to deal with
- The number and length of the joints
- How many areas need sealing
- Whether old sealant or filler has to be cut out
We don’t show prices on the website, because the cost depends so much on the job itself. For a quick quote, please call 0345 464 0079 or send us an email and we’ll talk you through it.

The process
On the day, we look over the joints with you first, so you know exactly what we are doing. We protect the surfaces around the joints before work begins. The work normally takes a few hours to a few days, depending on the length of joint and the access. For a job in Moulsecoomb, we agree the time, the access and parking before the day. If the work is outside, the weather plays a part, as sealant needs a dry surface.
- First we look over the joints with you, agree which to renew and talk through access.
- We cut out the failed sealant and rake out any dirt or growth.
- 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.
- We gun in a flexible exterior sealant in a colour that suits the wall and tool it neatly.
How to prepare
- Let us know about parking restrictions
- Clear items away from the joints we’re working on
- Tell us about any water getting in

Walls and rooflines in Moulsecoomb
Moulsecoomb is close to the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. That’s hard on movement joints and outside wall joints, especially on the side facing the sea. Historic houses like Preston Manor & Gardens (about 1.8 miles west) are a reminder that the area around Moulsecoomb 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.
For landlords with property near Moulsecoomb station, outside joints that have cracked can let damp into a rental, so check them between lets. In the older streets around St. Andrew's, the joints between older walls, newer extensions and the roofline need a sealant that can move.

DIY sealant or a professional job?
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it doesn’t work out, we can still put it right.
Honest limits
In fairness, there are a few things sealant will not fix:
- Movement that’s more than a sealant joint can take
- Adding movement joints to masonry that has none
- Damp that is not coming from the joint
If in doubt, call 0345 464 0079 or send us an email and we will say what we think before you book.
