How we handle new build mastic in Gordon Hill
A new build should have a neat, sound bead at every joint. Smeared, patchy or cracked sealant is worth sorting early, before water gets into the floor or walls. We are often asked to deal with joints pulling apart as timber shrinks and smeared, uneven beads picked up at snagging, across windows & doors, show homes and bathrooms & en suites.
New flats are going up across London, many of them in larger developments. Snagging there often goes through the developer or managing agent, and shower seals that fail early, skirting joints that open up and gaps at thresholds are all common snags.
All our work is covered by a 12-month guarantee, wherever you are in Greater London.

What new build mastic looks like in Gordon Hill
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. Many of London’s new homes are flats in bigger developments, where snags may need reporting through the developer or the managing agent.
If you’ve bought a new home near Gordon Hill station, the sealant around baths, showers and frames is worth checking in the first year or two.

Gordon Hill questions
I let a flat near Gordon Hill station. Can you help?
Yes, rental work is part of what we do. Just phone 0345 464 0079 or email us and tell us about the property, and we will give you a clear quote.
Can you do new build mastic in Gordon Hill?
Yes. We work across London and the South East, and Gordon Hill is part of that. You can ring 0345 464 0079 or email us and tell us what needs doing.
Is there a guarantee?
Yes, for a year. If anything isn’t right with the work within the year, let us know and we’ll sort it.
Do I need to be at home?
If the work is inside, we need someone to let us in. After that, you can carry on with your day.
Can new sealant go on top of the old bead?
No. Fresh silicone doesn’t stick to the old layer, so it soon lifts and traps water. We cut the old bead out completely.
What information do you need?
Tell us what needs doing and where, with pictures by email if possible. We’ll ask anything else we need to know.
Who should fix failed sealant in a new build?
Start with the builder if you are in the snagging or warranty period. If it isn’t resolved, we will cut it out and reseal it.
Can I send you my snagging list?
Yes. Snagging lists are a common starting point for us. We will go through the sealant items and agree what we will do.
How the visit works
You do not need to clear the whole room or building, just the space around the work. We protect the rest, and the job takes a few hours for most snagging lists, longer for a run of plots for a typical job. For a job in Gordon Hill, parking and access are the things to plan: let us know about parking, the floor we’ll be working on and any lift or shared entrance.
- We look at why each joint failed, including any movement.
- We remove the failed sealant and clean the joints.
- Joints are dried and primed where the product calls for it.

Different surfaces, different methods
Show homes
We can refresh show-home sealant that has discoloured or been knocked. We cut it out and reseal neatly.
Skirting and floors
New homes often develop a gap between skirting and floor. A flexible sealant closes it without cracking like caulk.
What happens if it’s left?
A hairline gap at a skirting can wait, but water getting through can’t. Not sure whether yours can wait? You can ring 0345 464 0079 or drop us an email with a few photos. Damp from a failed joint spreads quietly in older London brickwork and timber, and by the time it shows on a wall or ceiling in Gordon Hill, the repair is bigger than the sealant job would have been.
What you pay reflects the work, not a rough estimate. That’s why we ask about the job first.

Work for landlords, hotels and businesses
Mouldy or split sealant often shows up at the end of a tenancy, and it’s quick to put right between tenancies. We can quote for more than one property at once.
A neglected joint can let water reach the structure, which is a bigger problem in a rented property. Resealing at the right time is simple maintenance.

What affects the quote in Gordon Hill
There’s no set price list. The quote depends on:
- Whether the work is at height
- When we can work, for business premises
- How many areas need sealing
- Whether there’s mould to deal with
Some things make a job bigger or smaller: the old material and how easily it comes out, whether mould needs treating, and whether we need extra access for height. We take all of that into account in your quote.
What to tell us for a quote
Photos help, but a description is a good start. Please mention:
- Access, such as stairs, a lift or height
- If it’s domestic, commercial or a hotel
- Pictures of the joints, sent by email
- What’s wrong with the joints now
It all starts with a short chat. 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 0345 464 0079 or drop us an email.
Signs you need new build mastic in Gordon Hill
On many sites, sealant goes on in the final rush before handover. Joints are not always cleaned of dust or primed, and the sealant sits on grit instead of the surface.
People normally contact us when they notice one of these:
- Second-fix sealing on new plots
- Sealant that never bonded to the surface
- New-build shower sealant that has already split
- Gaps behind new kitchen upstands
Gordon Hill is in London, so parking needs planning: tell us about permits, visitor bays or off-street space when you book.
