Different surfaces, different methods
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.
Skirting and floors
Floors and skirting move as the house dries and the heating runs. We use a flexible product rather than caulk in a colour to suit.
About our new build mastic in Reston
Failed shower seals, gaps along the skirting and messy beads are common items on a new-home snagging list. If you are still within the builder’s snagging or warranty period, tell them first. We’re often asked to deal with second-fix sealing on new plots and cracked caulk along new skirting, on windows & doors, show homes and skirting & floors.
Many newer homes in Scotland are timber-framed and settle as they dry out, which shows as gaps at skirtings and floor joints. Older stone-built homes, meanwhile, often have timber floors that move with the seasons.
A 12-month guarantee comes as standard, so you’re not left on your own once the job is done.

- Plot handovers
- Bathrooms & en suites
- Windows & doors
- Skirting & floors
- Show homes

Keeping the joints in good condition
How long the joints last depends on use and care. We suggest:
- Use the extractor fan every time you shower
- Raise failed sealant with the developer while you are covered
- Avoid running a DIY bead over the old one
- Watch for new gaps as the house dries out
Avoid standing on the rim of the bath or the edge of the tray. Report any movement in a bath or tray.
Don’t let the snagging period run out with sealant problems unreported. After that, putting it right may fall to you so report it promptly.
Reston questions
Can you help a landlord with a rental near Reston station?
Yes. We work for letting agents and landlords as well as homeowners, and several properties can be quoted together. Just drop us a line at info@mrmastic.co.uk with the address and what needs doing, and we will give you a clear price.
Is Reston within the area you cover?
Yes, we do. Our work covers the whole of Scotland, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
What colour sealant will you use?
It depends on the joint: white or clear in most bathrooms, and a colour to suit worktops, frames and floors elsewhere. We agree the colour before any work starts.
Can I do it myself?
Some simple jobs can be done by a careful DIYer. Most DIY failures come from sealing over old material, wet joints or too much sealant.
Is it worth resealing while the house is still settling?
Where water is getting through, do not wait. Small gaps that are just cosmetic can be resealed once movement has slowed.
Is the work guaranteed?
Yes, always. There’s a 12-month guarantee on every job, large or small.
Is there any odour?
Some sealants have a smell while they cure, but it fades. Opening a window helps.
Will it make a mess?
Not at all. We work neatly, protect the area around the joints and tidy up afterwards.
Quotes for new build mastic in Reston
Some jobs are bigger than they look, and some smaller. What affects the quote:
- Access and height
- The number and length of the joints
- The type of sealant required
- The old material and how stubborn it is
What it costs depends on the size of the job, how hard the old material is to remove and how easy the joints are to reach. We give a clear quote before work begins.
Asking for a quote
Photos help, but a description is a good start. Please mention:
- Where the property is
- Whether it’s a home or a business
- Any access issues, like height or stairs
- The problem you’ve noticed
For new build mastic in Reston, drop us a line at info@mrmastic.co.uk. A short description of the job and where it is helps us quote, and you’ll get a clear quote before any work starts.
What happens if it’s left?
Running a new bead over the builder’s sealant might look tidy for a few weeks, but it cannot bond to what’s underneath. A lasting seal starts with removing the old one completely. In an older home around Reston, damp from a failed joint can get into timber and plaster.
A failed joint rarely gets cheaper to fix by waiting, as water and mould keep getting in. If you’re not sure whether it needs doing, email us at info@mrmastic.co.uk and we’ll give you an honest view and a quote.

How the visit works
We keep the work tidy and contained to the area we are working on, so you can get on with your day. Expect the work to take a few hours in a single home.

- First, the list of joints is agreed from your snagging sheet or plot schedule.
- The failed sealant is removed completely.
- Joints are vacuumed and cleaned of building dust.
- Primer goes on where the surface and product need it, then the new sealant.
- We tool every joint neatly and tell you when each area can be used.
Preparing for the visit
- Let us know if you’ve seen damp or leaks
- Try not to wet indoor joints just before the visit

What we’re called out for in Reston
A new house holds a lot of water from the build, and it dries out over the first couple of years. Drying timber shrinks and pulls joints apart, and sealant that can’t keep up splits.
Common reasons people contact us include:
- Joints pulling apart as timber shrinks
- Cracked caulk along new skirting
- Kitchen sealant that has pulled off the wall
- Second-fix sealing on new plots
In and around Reston, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.
