What new build mastic looks like in Avongrove
Many new homes in Scotland are timber-framed, so skirting and sealant joints can open up as the building settles. The west of Scotland is wetter than the east, which means plot mastic and the sealant in new homes has to cope with a lot of rain.
In and around Avongrove, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint. For new homes near Hamilton Central station, it’s worth checking the sealant early, while snags are still fresh.

How we handle new build mastic in Avongrove
Developers send us the plot schedule and we work through it. We seal bathrooms, kitchens, windows, doors and skirting so plots are ready to hand over. We work on windows & doors, plot handovers and bathrooms & en suites, and the jobs we see most are sealant that never bonded to the surface and new-build shower sealant that has already split.
For a place like Avongrove, the journey and access are planned in advance. Outdoor plot mastic needs dry weather, but indoor floor and skirting joints can be sealed whatever the forecast.
All of our work is guaranteed for twelve months, and the guarantee is the same wherever you are.

Should I try it myself first?
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
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.
What sealant work cannot fix
Sealant isn’t the answer to every problem, and we’d rather say so up front. Sealant won’t put right:
- Disputes or warranty claims with your builder
- Baths and trays that move too much for sealant to cope with
- Cracking that points to a structural problem
If in doubt, email us at info@mrmastic.co.uk and we will say what we think.
Surfaces we seal
- Kitchens
- Show homes
- Skirting & floors
- Windows & doors
- Plot handovers
- Bathrooms & en suites
Work for landlords, hotels and businesses
Letting agents often deal with us directly. Send the address, what’s needed and the access arrangements.
For anyone letting property in or around Avongrove, several properties can go on one quote. Just tell us the addresses and what each one needs.
Keeping the joints in good condition
How long the joints last depends on use and care. We suggest:
- Check bath and shower seals every few months as the house settles
- Record problems with dated pictures
- Put sealant faults on your snagging list early
- Open a window or run the fan after bathing
Watch the joints as the house settles. Small gaps can appear as the house dries.
The sooner you deal with untidy or cracking sealant, the less there is to put right. Left alone, a small crack can become a leak.
How we quote for new build mastic
The price is agreed before any work begins. It’s based on:
- The number of rooms or windows
- Whether old sealant or filler has to be cut out
- The size of the job
- The product the joint needs
What it costs depends on the amount of work, how much old material has to come out and access to the work. You will have a clear quote before any work starts, so you know where you stand.
What we need to know
The more you tell us, the more accurate the quote. When you ask for a quote, tell us:
- Whether it has been sealed before
- What’s wrong with the joints now
- Where the property is
- Roughly how big the job is
Need a quote? Please send an email to info@mrmastic.co.uk and tell us about the job. We’ll explain what we’d do and send you a clear quote before any work starts.
What happens on the day
Before we leave, we go over the finished joints with you and explain the cure time. The work normally takes anything from a few hours to several days, depending on the number of plots, depending on the size of the job. Outside jobs in Avongrove need a dry day, because sealant won’t bond to a wet joint, so external jobs may need to move if the day turns wet. Work indoors isn’t affected.
- We start by agreeing which joints are on the list, from the snagging sheet or plot schedule.
- Failed or untidy sealant is cut out completely.
- Each joint is cleaned of dust and grit, then primed if required.
- 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.
Before we arrive
- Tell us about any previous sealing or DIY attempts
- Where the joints are inside, avoid wetting them before we arrive
- Keep children and pets away from the work area
Getting a quote
It all starts with a short chat. Tell us what’s wrong, where it is and how much there is, and we will talk you through what we’d do. Whenever you’re ready, email us at info@mrmastic.co.uk.

Kitchens
Worktops in new homes can move slightly as the house dries, which opens gaps along the back. A fresh flexible bead closes them.
Bathrooms and en suites
Shower trays in new homes often move slightly in the first year. The joint is stripped back before the new bead goes in and baths are filled before sealing.
