New build mastic for homes and businesses in Buckland
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 skirting joints opening in the first winter and smeared, uneven beads picked up at snagging, on plot handovers, skirting & floors and show homes.
Around Buckland, older homes often have timber floors that move through the year, which is why skirting and threshold joints need a flexible sealant, not filler.
We stand behind the work with a one-year guarantee, so you’re not left on your own once the job is done.

The process
Good joint work is mostly preparation, and we don’t rush it. Every joint is cleaned and dried before new material goes in. In total, it generally takes anything from a few hours to several days, depending on the number of plots. In a small place like Buckland, access is normally the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- 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.
- Baths are filled with water, then the new sealant is applied.
- The finished joints are checked and the cure times given.
Getting ready for the visit
- Mention if the joints have been sealed before
- On commercial sites, let us know about site rules
- Try not to wet indoor joints just before the visit

Advice
Should I try it myself first?
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it does not work out, we can still put it right.
If you’ve already had a go yourself, that’s fine. We cut it out and start again, so tell us about it when you ask for a quote.

Aftercare tips
Simple care keeps the joints in good condition. We recommend:
- Report sealant problems to your builder during the snagging period
- Look at the sealant regularly in the first couple of years
- Resist patching a failed seal with a tube from the DIY shop
- Avoid scourers and strong chemicals on sealant
Keep an eye on the joints over the first couple of years. Small gaps can appear as the house dries.
Lifting sealant traps moisture and mould behind it. Dealing with it before it goes black keeps the job straightforward.
New build mastic in Buckland: local notes
Rainfall in the South East is lower than in much of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.

Why act early in Buckland
A tube of sealant from the DIY shop won’t fix the cause: dust, no primer and old sealant left in the joint. Cutting out, cleaning and priming are what make the difference. In a small place like Buckland, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
Leaving a failed joint normally makes the job bigger, not smaller. If you’re not sure whether it needs doing, ring 0345 464 0079 or send us an email for an honest opinion and a quote.

When to call us in Buckland
A new house holds a lot of water from the build, which takes a year or two to dry out. As it does, timber shrinks and joints open.
The most common problems we see are:
- Cracks appearing as a new home settles
- Messy sealant that spoils new finishes
- Skirting joints opening in the first winter
- Cracked sealant around new window and door frames
If you’ve bought a new home near Royston station, the sealant around baths, showers and frames is worth checking in the first year or two.
What to look for in a quote
- Which colour the sealant will be
- How the surfaces are prepared before sealing
- Is VAT in the price?
- What insurance they hold
Different surfaces, different methods
Windows and doors
A draught at a new window can be a missed or failed joint. We check and reseal the frame edges.
Kitchens
Worktops in new homes can move slightly as the house dries, which opens gaps along the back. A fresh flexible bead closes them.
