Patching: your questions answered
Will you come out to Patching?
Yes, Patching is covered. We work across London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
Can you help a landlord with a rental near Chelmsford station?
Yes, landlords and agents are among the people we work for. Just ring 0345 464 0079 or email us with the address and what needs doing, and we will give you a clear quote.
Can you seal over the old sealant?
No. New silicone will not bond to old silicone, and anything trapped underneath, including mould and water, stays there. It all has to come out first.
Is it OK to fill a movement joint with cement?
No. Mortar locks the joint solid, so the wall cracks somewhere else instead. It needs a flexible sealant over backing rod.
When is the sealant fully cured?
Many sealants skin over quickly but take longer to cure fully. We’ll tell you how long to leave the joint before we leave.
Do you have insurance?
Yes. Full insurance covers our work, and we can confirm the details when we quote.
What colours does the sealant come in?
The sealant colour is picked to suit the wall, so the joint sits quietly in the wall. Exterior sealants come in a good range of colours.
What information do you need?
The location, the problem and the rough size of the job. Photos by email help too.
External mastic in Patching, done properly
We cut out failed sealant, set the joint depth with closed-cell backing rod and reseal with a low-modulus exterior sealant. We pick a colour that sits well with the wall so the joint doesn’t stand out. We work on façade panels, render & cladding joints and concrete & block, and people most often call us about joints where the bead has come unstuck and moss and dirt in joints with no sealant left.
In a smaller place like Patching, some homes face open ground, so exposed walls and rooflines take more wind-driven rain. That is where gutter joints and wall joints tend to fail first.
Whatever the size of the job, it’s backed by our 12-month guarantee.

Looking after it afterwards
Good habits help new joints last longer. A few tips:
- Have failed joints looked at early
- Don’t let climbing plants root in the sealant
- Avoid pressure-washing directly into sealant joints
- Keep movement joints as flexible joints, not mortar
Do not paint over the new sealant unless we have said the product is paintable. Many exterior sealants are not designed to be painted and spoil the finish.
A joint that has stopped moving pushes the movement elsewhere, often as cracks near the joint. Catch it early and you reduce the risk.
Should I try it myself first?
A DIY attempt doesn’t rule out a professional job. We remove it and do the joint properly, so just mention it when you contact us.
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
Why it’s worth doing now in Patching
The longer a joint stays open, the more water the wall takes in. Wet masonry is more easily damaged by frost around the joint, so the problem grows beyond the joint itself. Homes in smaller places like Patching can face more weather, and failed outside joints let damp into walls. Inside, a split seal lets water into floors and panels just as it would anywhere.
Leaving a failed joint usually makes the job bigger, not smaller, because water and mould keep working on it. If you’re not sure whether it needs doing, ring 0345 464 0079 or send us an email for an honest opinion and a quote.

What the job involves on each surface
Concrete and blockwork
Concrete and block walls shrink as they dry and move with temperature. Their movement joints are sealed over backing rod with a flexible sealant.
Render joints
Rendered walls have joints at beads, openings and changes of material. We reseal them with a flexible exterior sealant that suits the render colour.
How it works
Every visit runs the same way: we look at the joints together, protect the area around them, carry out the job and tidy away. It usually takes anything from a few hours to several days, depending on the building. Parking around Patching is usually easier than in a town centre, but mention any lanes, gates or long drives. If the job is outside, tell us about side access and how high the joints are.
- We start by checking each joint, agreeing the ones to redo and how we’ll reach them.
- 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.
Getting ready for the visit
- Try not to wet indoor joints just before the visit
- Plan for the work area to be out of bounds to pets and children
- Mention any parking rules near the property

What we can’t put right
A few problems are outside what sealant work can do:
- Cutting new joints into brickwork, which is building work rather than sealant work
- Failed render or damaged cladding panels
- Damp from another source, such as a leaking gutter or a bridged damp-proof course
If you are not sure, just ring 0345 464 0079 or email us and we will give you a straight answer before you book.

External mastic in Patching: local notes
With historic houses such as Hylands (about 3 miles south-west) nearby, there’s older building stock in the area around Patching as well as newer homes. Where a home is older, older walls and rooflines need a sealant that moves with them and suits the material. Compared with the north and west, the South East gets less rain, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
If you look after a building such as St John Payne Catholic School, its movement joints, gutters and trims need looking after like any other building’s. Rented homes near Chelmsford station change hands often, and split movement joints are easy to miss on a rental until damp shows inside. Hylands, about 3 miles south-west, is one of the historic houses in the wider area around Patching.
