Newyears Green questions
Is parking an issue for external mastic in Newyears Green?
In much of London, parking needs planning: a visitor permit or a nearby bay makes the day run more smoothly, so mention what’s available when you book.
Can you help a landlord with a rental near West Ruislip station?
Yes, rental work is part of what we do. Just phone 07833 053749 or drop us an email and tell us about the property, and we’ll give you a clear price.
Where are you based?
Our base is Crawley. We work across South East England, London and Scotland.
Do you use backing rod?
We fit closed-cell backing rod wherever the joint depth needs controlling. It sets the sealant depth and prevents three-sided bonding so the bead can stretch.
Can new sealant go over the old?
No, because it fails. The old sealant always comes out first, so the new joint bonds to clean surfaces.
Do the sealants smell?
It depends on the product. Some products have a noticeable smell, others very little, and any smell fades as they cure.
Does someone need to be in?
It depends on the job. Inside work needs someone to give us access, and for outside work we’ll agree access with you when we book.
Can I do it myself?
You can, for simple jobs. The key is preparation: remove all the old material and work on a clean, dry joint. If it doesn’t work out, we can redo it.
External mastic for homes and businesses in Newyears Green
Many failed façade joints only get noticed once there’s a stain or a damp patch inside. We look over the joints, agree the ones to renew and reseal with a flexible, weatherproof product in a colour to suit. If you have old sealant gone brittle and cracked and brick movement joints where the sealant has split, we can put it right, on concrete & block, brickwork movement joints and render & cladding joints alike. Mastic man, silicone man or sealant specialist, the name varies, but the work in Newyears Green is the same: old material out, joints prepared and the right product used.
London’s terraces and conversions often share walls, gutters and downpipes with their neighbours, so a leaking gutter joint or failed wall joint can affect more than one home. For a flat in Newyears Green, check the lease for who looks after the outside.
The work is covered for a year after we finish. If there’s a problem with it, please phone 07833 053749 or drop us an email.

Keeping the joints in good condition
So the new joints stay in good condition:
- Check external joints each spring
- Have failed joints looked at early
- Keep soil, plants and ivy away from the joints
- Tell anyone working on the walls about the movement joints
If you have more work done on the wall, such as new render, cladding or an opening, show the contractor the movement joints. They must stay as flexible joints, never rendered or pointed over.
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 affects the quote in Newyears Green
The price is agreed before any work begins. It takes into account:
- The old material and how stubborn it is
- The amount of work
- The type of sealant required
- Working hours on commercial sites
Doing several joints on one visit is usually more efficient than separate visits, so tell us about everything that needs sealing. You will get one clear quote for the whole job.
What we need to know
Photos by email are helpful but not essential. Please mention:
- What the problem is, such as mould, gaps, leaks or cracking
- Roughly how big the job is
- The type of property
- Access, such as stairs, a lift or height
Quotes start with a quick conversation. Describe the problem, the location and the size of the job, and we will talk you through what we’d do. Whenever you’re ready, phone 07833 053749 or drop us an email.
Newyears Green buildings and the weather
With historic houses such as Ickenham Hall (about 1.5 miles south-east) nearby, there’s older building stock in the area around Newyears Green as well as newer homes. Where a home is older, older brick and stone need a sealant that suits them, at the right joint depth. London terraces and converted houses often share gutters, downpipes and walls, so it’s worth agreeing who is responsible before work starts.

DIY sealant or a professional job?
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.
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and does not move well, and getting the depth right matters as much as the look.
Honest limits
We won’t take on work that won’t last, so here’s what sealant cannot put right:
- Render that’s blown, hollow or coming away
- Cracks in the bricks or render themselves, away from the joints
- Adding movement joints to masonry that has none
If you are not sure, just phone 07833 053749 or send us an email and we’ll give you a straight answer.
