How we quote for new build mastic
For a quick quote, just ask. The main things that affect it are:
- Access and height
- Whether there’s mould to deal with
- The product the joint needs
- The amount of work
Doing several joints on one visit is generally more efficient than separate visits, so it’s worth mentioning everything you’d like done. We’ll send you a clear quote for the lot.

- Where the property is
- The type of property
- How many joints, rooms or windows are involved
- What the problem is, such as mould, gaps, leaks or cracking
Quotes start with a quick conversation. Tell us what’s wrong, where it is and how much there is, and we’ll talk you through what we’d do. When it suits you, call 0345 464 0079 or send us an email.
How we handle new build mastic in Toy's Hill
A new build should have a neat, sound bead at every joint. When the finish is smeared, patchy or already cracking, it’s worth putting right early, before water reaches anything behind it. Common call-outs are for cracks appearing as a new home settles and cracked caulk along new skirting, on plot handovers, skirting & floors and windows & doors.
Across London, commercial floors have movement joints that break down under heavy foot traffic, and new homes need their plot mastic finished properly before handover, in Toy's Hill and beyond.
Each job carries a 12-month guarantee.

Questions from Toy's Hill
I let a flat near Edenbridge station. Can you help?
Yes, we work for landlords and agents. You can phone 0345 464 0079 or email us with the address and a few details, and we’ll give you a fixed price before we start.
Is Toy's Hill in your area for new build mastic?
Yes. Our work covers London and the South East, and Toy's Hill is part of that. Just phone 0345 464 0079 or email us with a few details of the job.
What sealant do you use?
Each joint gets the product that suits it. Where it moves, gets wet or faces the weather makes a difference, and we will tell you what we’re using.
How do I get a quote for new build mastic in Toy's Hill?
There’s no set price, as it depends on the job: its size, the old material, access and the product needed. We agree the price before any work begins.
Is it worth resealing while the house is still settling?
That depends on the joint. A leaking shower or bath seal should be redone right away, but cosmetic gaps can wait for movement to slow.
Should I go to my builder first?
Start with your builder while their snagging or warranty period runs. If that does not work out, we’re happy to quote with our 12-month guarantee.
Can you reseal over the builder’s sealant?
No. Fresh silicone doesn’t stick to the old layer, so sealing over the top fails quickly. The old sealant always comes out first.
Do you work through snagging lists?
Yes. Send us the sealant items on the list, with photos if you can, and we will quote. We’ll tell you if anything on it isn’t a sealant job.
What sealant work can’t fix
Some problems need a builder, plumber or other trade rather than us:
- Disputes or warranty claims with your builder
- Leaking fittings rather than failed sealant
- Broken tiles or a split tray
If you’re not sure, just call 0345 464 0079 or drop us an email and we will give you a straight answer.

How it works
We bring everything the job needs with us, so there’s nothing for you to buy. Once we’ve agreed what’s being done, the area is protected and the work begins. Most jobs take a few hours in a single home. Many London jobs are in flats, so we come ready for stairs, narrow hallways and shared entrances. Mention any building rules, key holders or managing agents when you book.
- We start by going through the snagging items or plot schedule with you.
- The failed sealant is removed completely, with no layer left behind.
- We clean out the dust and grit left from the build.
- We prime where needed and apply a sealant suited to each joint.
- Each bead is tooled and the cure times explained.
Before we arrive
- Where the joints are inside, avoid wetting them before we arrive
- Keep pets and children clear of the area while we work
- Clear items away from the joints we’re working on

Advice
Joints and finishes in Toy's Hill homes
Much of London’s new housing is flats in larger developments, where snags may need reporting through the developer or the managing agent. Rainfall in the South East is lower than in much of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
Toy's Hill is in London, so parking needs planning: let us know about parking bays, permits or a driveway.

What’s near Toy's Hill
Around Toy's Hill, our work takes us to homes and buildings near Stubbs Wood Country Park and The Cock Inn. Toy's Hill’s nearest station is Edenbridge station, about 3.2 miles south-west.

How to look after the new joints
Looking after new joints is easy, and it makes a real difference:
- Do not seal over failed sealant yourself
- Avoid scourers and strong chemicals on sealant
- Look at the sealant regularly in the first couple of years
- Get a leaking seal dealt with right away
Keep the bathroom ventilated, especially in the first year. Run the fan or open a window after bathing to help keep mould away.
Mould takes hold quickly in sealant that has gaps or lifted edges. Dealing with it before it goes black keeps the job straightforward.
Common problems we fix in Toy's Hill
Once people move in, baths and trays take weight and bed down. A bath sealed empty drops slightly when filled, straining the joint and the sealant may split.
Common reasons people contact us are:
- Second-fix sealing on new plots
- Frame joints opening as the plaster dries
- Beads laid onto grit and dust from the build
- Gaps behind new kitchen upstands
For new homes near Edenbridge station, it’s worth checking the sealant early, while snags are still fresh.
Comparing quotes

- Which colour the sealant will be
- Whether they’re fully insured

Different surfaces, different methods
Skirting and floors
As timber and screed dry, skirting and floors shift. We use a flexible product rather than caulk painted or coloured to suit.
Plot handovers
Good preparation at handover saves snagging later. We clean out building dust before sealing and primer used where needed.

Leave it or put it right?
Small cosmetic gaps can wait for the house to settle, but water getting through cannot. Not sure whether yours can wait? You can ring 0345 464 0079 or send us an email with a few photos and we will tell you. In a London flat, a failed joint rarely stays your problem alone: water can reach the neighbours below, and gaps in fire-rated joints affect the whole building.
Every job is a little different, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all make a difference.
