About our new build mastic in Caterham
New homes move as they dry out. Timber dries and shrinks, and baths and trays settle, and sealant applied in a hurry at handover can split. Typical jobs include messy sealant that spoils new finishes and shower seals failing in the first year or two, on bathrooms & en suites, skirting & floors and show homes.
Shops and business units around Caterham have floors that see a lot of traffic. Joints at thresholds and in tiled or concrete floors need resealing before the edges start to break up.
Every job comes with a 12-month guarantee.

Caterham: your questions answered

What information do you need?
The location, the problem and the rough size of the job. Photos by email help too.
Can you match the sealant colour to my new kitchen or bathroom?
White and clear are the most common, but sealant comes in other colours too. We choose one to suit the room.
Is it normal for sealant to crack in a new home?
There are usually two causes: the house moving as it dries, and sealant that never bonded properly. Cutting it out and resealing properly fixes both.
Can you do several jobs on one visit?
Yes. Several rooms, windows or areas can go on one quote.
Can you work from my snagging list?

What affects the cost of new build mastic
The quote reflects the job in front of us. We take into account:
- Which sealant suits the joint
- How much there is to do
- Any mould that needs treating
- Whether the work is at height
A few things move the cost up or down: the old material and how easily it comes out, whether mould needs treating, and whether we need extra access for height. Your quote takes all of that into account.
Asking for a quote
The more you tell us, the more accurate the quote. When you ask for a quote, tell us:
- Access, such as stairs, a lift or height
- What the problem is, such as mould, gaps, leaks or cracking
- Roughly how big the job is
- The address or postcode of the job
We quote each job on its own. Just ring 0345 464 0079 or drop us an email with the details and send pictures if you have them.

Why deal with it now?

If you’re unsure which you have, phone 0345 464 0079 or send us an email with photos and we will give you a straight answer. Around Caterham, failed sealant lets water into hidden places, such as under the floor, behind a panel or into a wall. Whatever the joint, failed sealant only gets worse.

Common problems we fix in Caterham
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.
Any of these means the joints need attention:
- Shower seals failing in the first year or two
- Kitchen sealant that has pulled off the wall
- Cracks appearing as a new home settles
- Beads laid onto grit and dust from the build
Around Caterham, as everywhere, new build mastic is only as good as the preparation behind it.
Before you book anyone
- Who does the work, and how experienced they are
- Whether VAT is included
- Which sealant they’ll use, and why
- Whether they seal over old material or remove it
How the visit works
On the day, we start by going over the job with you, so you know exactly what we are doing. We protect the surfaces around the joints before any work begins. The work usually takes anything from a few hours to several days, depending on the number of plots. In Caterham, parking is rarely complicated, though it helps to know about driveways or restrictions, and mention if the work is upstairs, in a flat or high on the outside.
- First, the list of joints is agreed from your snagging sheet or plot schedule.
- Every bit of the old builder’s sealant is cut out.
- We clean out the dust and grit left from the build.
- Primer goes on where the surface and product need it, then the new sealant.
- Each bead is tooled and the cure times explained.
Before we arrive
- For indoor joints, keep the area dry beforehand if you can
- Mention if the joints have been sealed before
- Mention any leaks or damp you’ve noticed

DIY versus a professional finish
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.
Different surfaces, different methods
Show homes
Show homes need sealant that looks right from day one. Every bead is neat and coloured to suit the room.
Bathrooms and en suites
En suite showers are a common source of leaks into the room below. A proper reseal keeps water in the tray.
