New build mastic for homes and businesses in Sulham
New homes move as they dry out. Timber dries and shrinks, and baths and trays settle, so sealant that was laid quickly before handover often cracks. If you have gaps opening as the house dries out and settles and gaps between new skirting and floors, we can put it right, whatever the surface.
Older homes in small places like Sulham often have timber floors that move with the seasons, which is why skirting and threshold joints need a flexible sealant, not filler.
You’re covered for a year from the day we finish. If there’s a problem with it, please call 0345 464 0079 or send us an email.

How to look after the new joints
To keep the joints looking good and working properly:
- Do not wait for the house to settle if water is getting through
- Check bath and shower seals every few months as the house settles
- Resist patching a failed seal with a tube from the DIY shop
- Keep water off fresh sealant until it has cured
Wipe the sealant with warm soapy water. Avoid abrasive pads and strong solvents.
If a shower tray or bath seal splits in the first year, look for movement. Getting it resealed properly, and any movement checked, stops it recurring.
Sulham questions
Can you do new build mastic in Sulham?
Yes. We work across London and the South East, and Sulham is part of that. Just ring 0345 464 0079 or send us an email with a few details of the job, and we’ll send you a clear quote.
Will you come out to Sulham?
Yes, Sulham 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.
Are you fully insured?
Yes. We are fully insured, and we can confirm the details when we quote.
How long before the joint can be used?
Different products cure at different speeds, so follow the cure time we give you when we finish.
Is the work guaranteed?
Yes, for a year. If there’s a problem with our work in that time, tell us and we’ll put it right.
Should I wait before resealing?
That depends on the joint. A leaking shower or bath seal should be redone straight away, while small cosmetic gaps can wait a while.
Can you match the sealant colour to my new kitchen or bathroom?
It depends on the joint: white or clear for most sanitary joints, colours for worktops, floors and frames. We will agree it with you first.
Does someone need to be in?
Access is agreed with you when the job is booked. For inside work, that normally means someone being in.
What we do, step by step
When we get to you, we compare the joints with what we discussed. If anything is different, we explain it before carrying on. After that, the work takes a few hours in a single home. In a small place like Sulham, access is generally the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- First we work through your snagging list or plot schedule with you.
- Failed or untidy sealant is cut out completely.
- Surfaces are cleaned of building dust and primed where needed.
- A sealant chosen for each area goes in and is tooled smooth.
- We check every joint and tell you how long each needs to cure.
Preparing for the visit
- Let us know about earlier repairs to the joints
- Move anything stored near the joints
- Let us know if you’ve seen damp or leaks

What affects the quote in Sulham
Your quote is based on your job. We look at:

- Where the job is, and your postcode
- What the problem is, such as mould, gaps, leaks or cracking
- If someone has resealed it before

What we’re called out for in Sulham
Once people move in, baths and trays take weight and bed down. If a bath wasn’t filled when it was sealed, the bead is stretched the first time it’s used and the sealant may split.
Signs it’s time to call us include:
- Gaps behind new kitchen upstands
- Beads laid onto grit and dust from the build
- Second-fix sealing on new plots
- Internal frame sealant that has split
In and around Sulham, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.

Surface by surface
Skirting and floors
Floors and skirting move as the house dries and the heating runs. Caulk cracks; a flexible sealant moves with it in a colour to suit.
Bathrooms and en suites
En suite seals are easy to miss on a snagging list until they leak. A proper reseal keeps water in the tray.
Work for landlords, hotels and businesses
From a single let to a portfolio, you get the same standard of work: the old material taken out, careful preparation and a 12-month guarantee.
Letting agents often deal with us directly. Send the address, what’s needed and the access arrangements and we will quote.
Joints and finishes in Sulham homes
Rainfall in the South East is lower than in much of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
