Surface by surface
Render joints
Render has movement joints and stop beads that need sealing. We reseal them with a flexible exterior sealant that suits the render colour.
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.
External mastic in Marlow Common
On houses, flats and commercial buildings across Marlow Common, we reseal joints in brickwork, render, cladding and façade panels. Every joint gets the same careful preparation: clean joint faces and the right depth. If you have plants rooting in failed movement joints and rigid filler in a joint that should flex, we can put it right, whatever the surface.
Outside joints can only be sealed when they’re dry, so work in Marlow Common is booked around the forecast. Tell us about access to all sides of the building, including outbuildings and garages.
All of our work is guaranteed for twelve months, in Marlow Common and everywhere else we cover.

Keeping the joints in good condition
How long the joints last depends on use and care. We suggest:
- Have failed joints looked at early
- Do not let climbing plants root in the sealant
- Check the sealant is paintable before painting near it
- Wash walls gently around the sealant
Do not paint over the new sealant unless we’ve said the product is paintable. Many exterior sealants are not designed to be painted and spoil the finish.
Leave a failed movement joint and water keeps getting into the wall. That can lead to damp patches, staining and frost damage.
Should I try it myself first?
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 difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions.
Why deal with it now?
Mortar or ordinary filler might look like a quick way to close an open joint, but it locks the joint solid. The movement then cracks the brickwork or render nearby. A flexible sealant over backing rod is what the joint needs. Where a wall is exposed, as many are in small places like Marlow Common, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
Homes and businesses are quoted the same way: the amount of work, the access and the products needed, plus any working-time requirements on site. Call for a quick quote and we’ll go through it with you.

Marlow Common questions
Is Marlow Common within the area you cover?
Yes, smaller places are covered as well as towns. Our work covers London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Can you do external mastic in Marlow Common?
Yes. We work across London and the South East, and Marlow Common is part of that. You can call 0345 464 0079 or email us and let us know what needs doing.
Do you remove the old sealant?
Yes, always, and completely. New sealant will not bond properly to old, so any old material comes out before anything new goes in.
Do you guarantee your work?
Yes. Every job comes with a 12-month guarantee.
Are you ARBOMaster approved?
Yes. We’re an ARBOMaster approved applicator, which is run for the Arbo sealant brand.
Do you use backing rod?
Backing rod goes into deeper joints as a matter of course. It sets the sealant depth and prevents three-sided bonding, so the joint can move.
How much does external mastic cost in Marlow Common?
The cost depends on the size of the job, access and how much old sealant has to come out. Call for a quick quote.
Can landlords and businesses book you?
Yes, we do. We work in homes, commercial premises and hotels.

What we do, step by step
Most of a good job is in the preparation, and we don’t rush it. Every joint is cleaned and dried before new material goes in. In total, it generally takes a few hours to a few days, depending on the length of joint and the access. Somewhere as small as Marlow Common, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- 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.
- Both sides are cleaned back to sound material and primed if needed.
- 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.
Getting ready for the visit
- Move anything stored near the joints
- Try not to wet indoor joints just before the visit
- Tell us if parking is tricky

What sealant work can’t fix
New sealant can’t fix everything, and we will tell you before any work starts. Sealant won’t put right:
- Cracking across the wall rather than at a joint
- Rising or penetrating damp from elsewhere in the wall
- Failed render or damaged cladding panels
If in doubt, ring 0345 464 0079 or send us an email and we will say what we think before you book.
Joints and surfaces we work on

Outside joints around Marlow Common
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. Historic houses like Harleyford Manor (about 1.6 miles south) are a reminder that the area around Marlow Common has older buildings as well as new. In older buildings, older brick and stone need a sealant that suits them, at the right joint depth.

Then its movement joints, gutters and trims need looking after like any other building’s.
