External mastic for homes and businesses in Margaret Roding
Ground-floor and low-level joints are straightforward to reach. For joints higher up, give us some details of the building and we will confirm what access is needed. Common call-outs are for failed sealant between panels on a façade and plants rooting in failed movement joints, on copings & trims, render & cladding joints and joints between brick and frames.
Outside joints can only be sealed when they’re dry, so work in Margaret Roding is booked around the forecast. Let us know about access to every wall, plus any garages or outbuildings.
The work is guaranteed for twelve months. If something is not right with it in that time, tell us and we’ll put it right.

How to look after the new joints
Aftercare is simple:
- Clear growth from the base of walls and joints
- Look over the joints every year, ideally after winter
- Keep high-pressure jets off the joints
- Leave the joints unpainted unless we’ve said otherwise
Don’t let soil, plants or ivy build up against the new joints. Anything that holds water against the joint wears it out sooner.
Once a joint can’t move, the wall finds another way, usually as cracking in the brickwork or render nearby. Catch it early and you reduce the risk.

What happens if it’s left?
Resealing a run of joints in one go is normally better than patching one at a time. Joints of the same age tend to fail together. In a small place like Margaret Roding, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
Combining jobs into one visit normally makes better use of the time than several visits. We’ll give you a clear quote for the lot.

External mastic in Margaret Roding: local notes
London and the South East are among the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind. Historic houses like Barrington Hall (about 4.8 miles north-west) are a reminder that the area around Margaret Roding has older buildings as well as new. Where a home is older, older walls and rooflines need a sealant that moves with them and suits the material.
For an older house near a landmark such as Parish Church of St Margaret, an extension built onto an older house moves differently, and the joint between them takes the strain.

When to call us in Margaret Roding
Buildings move more than people expect. Brickwork grows a little over the years, blockwork and concrete shrink, and all of it moves with heat and moisture. All of that ends up in the joint sealant.
Most people get in touch when they notice something like this:
- Rigid filler in a joint that should flex
- Plants rooting in failed movement joints
- Brick movement joints where the sealant has split
- Old sealant gone brittle and cracked
Around Margaret Roding, as everywhere, external mastic is only as good as the preparation behind it.
What to look for in a quote
- What product goes in the joint
- How much experience the applicator has
- How the joint is cleaned and prepared
- Is the old sealant removed completely?
What happens on the day
We work through the job in order: protect, prepare, seal, tidy. Typically it takes a few hours to a few days, depending on the length of joint and the access and we leave things clean and tidy. In a small place like Margaret Roding, access is usually the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- We start by checking each joint, agreeing the ones to redo and how we will reach them.
- Old sealant and any debris are cut and raked out.
- We clean both faces of the joint and prime them where the product calls for it.
- Closed-cell backing rod is fitted to set the depth and stop three-sided bonding.
- A flexible exterior sealant is applied and tooled in a colour to suit the wall.

Advice
DIY versus a professional finish
A DIY attempt does not rule out a professional job. We remove it and do the joint properly.
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions, and the work is guaranteed for a year.
Margaret Roding questions
What guarantee comes with external mastic in Margaret Roding?
All our work, in Margaret Roding and everywhere else, comes with a 12-month guarantee. We are also fully insured and ARBOMaster approved.
Do you cover Margaret Roding for external mastic?
Yes, Margaret Roding is within the area we cover. We work across London and the South East. Just call 0345 464 0079 or email us with a few details of the job, and we’ll give you a clear quote.
Will the new joint stand out?
We aim for a joint that suits the wall rather than one that jumps out. We’ll talk through colour options before any work starts.
Can you do several jobs on one visit?
Yes, we can. Several rooms, windows or areas can go on one quote.
Will the old sealant be removed?
Yes, always, and completely. New silicone does not stick to old silicone, so the joint is cleaned back first.
What is a movement joint?
It’s a deliberate gap that lets the wall expand and contract without cracking. It should be filled with flexible sealant, never mortar.
What should I tell you?
The location, the problem and the rough size of the job. If you can, email a few photos.
When will the joints need doing again?
It varies with how exposed the wall is and how much the joint moves. Signs to watch for are cracking, hardening and gaps at the edges and have them redone then.
For landlords and businesses
Hotels need rooms back in use, so we plan the work room by room. Hotel work is part of what we do, alongside homes and businesses.
We also work for businesses, from offices to washrooms and kitchens. On commercial sites, working times can be discussed when we quote.
