About our new build mastic in Matchams
A new build should have a neat, sound bead at every joint. Smeared, patchy or cracked sealant is worth sorting early, before water reaches anything behind it. We work on bathrooms & en suites, windows & doors and skirting & floors, and common reasons people get in touch are gaps opening as the house dries out and settles and smeared, uneven beads picked up at snagging.
Work in a small place like Matchams just needs the journey and access planning, and the work itself is the same as on any site.
The work is guaranteed for twelve months. If there’s a problem with our work within the year, let us know and we’ll sort it.

How we quote for new build mastic
Every job gets its own quote. This is what makes a difference:
- The product the joint needs
- Any mould that needs treating
- Access and height
- How many areas need sealing
Every job is a little different, so each one gets its own quote. Size, access and the product the joint needs all play a part, and we’ll explain the quote if you ask.
What to tell us for a quote
A few details help us give you an accurate quote. When you ask for a quote, tell us:
- Any previous sealing or DIY work
- The problem you’ve noticed
- The rough size of the job
- Where the job is, and your postcode
Getting a quote is simple: let us know the job and the location, and roughly how big it is. A few pictures by email make the job easier to understand, and we will come back to you with a quote.
For landlords and businesses
From a single let to a portfolio, the work is the same standard: the old material taken out, careful preparation and a 12-month guarantee.
Housing providers, facilities teams and property managers book us too. We can quote a run of properties together.
Common problems we fix in Matchams
If plaster or screed was still damp when it was sealed, the bond suffers. On a busy site, joints are not always given time to dry before the sealant goes on.
The problems people normally mention when they call are:
- Internal frame sealant that has split
- Skirting joints opening in the first winter
- Worktop and upstand sealant coming away
- Joints pulling apart as timber shrinks
Around Matchams, as everywhere, new build mastic is only as good as the preparation behind it.

How to look after the new joints
Looking after new joints is easy, and it makes a real difference:
- Avoid scourers and strong chemicals on sealant
- Act quickly if a seal starts to leak
- Report sealant problems to your builder during the snagging period
- Resist patching a failed seal with a tube from the DIY shop
Ventilation matters in a new home, which is still drying out. Use the extractor fan or open a window after showers so moisture does not sit on the sealant.
A failed seal in a new home lets water into joists, plasterboard and ceilings. Early resealing keeps the job small.

What sealant work can’t fix
Some problems need a builder, plumber or other trade rather than us:
- Deciding who is responsible under a builder’s warranty
- Settlement cracks that need a surveyor
- Cracked trays, tiles or worktops
If in doubt, phone 0345 464 0079 or email us and we’ll say what we think before you book.

What happens on the day
At the end, we look at the finished work together and tell you how long to leave it. The work normally takes a few hours for most snagging lists, longer for a run of plots, depending on how much there is to do. Somewhere as small as Matchams, access is often the only tricky part. 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.
- We cut out every bit of the failed or messy sealant.
- Surfaces are cleaned of building dust and primed where needed.
- A sealant chosen for each area goes in and is tooled smooth.
- Finally, each room is checked and you’re given the cure time.
Before we arrive
- Clear items away from the joints we are working on
- Mention if the joints have been sealed before
- Tell us about access, such as stairs, a lift or high-level joints

Advice
New build mastic around Matchams
The South East is one of the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
Whether the job is in Matchams itself or nearby, the right material for each joint matters as much as a neat finish.

Can I do it myself?
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
