New Build Mastic in Hermiston
Problem with your new-build sealant joints in Hermiston? We remove the old material, prepare the joints and seal them properly, and the work is guaranteed for a year.
- Frame joints opening as the plaster dries
- Joints pulling apart as timber shrinks
- Beads laid onto grit and dust from the build
How we handle new build mastic in Hermiston
Some owners wait for the first year’s movement before having joints redone. That makes sense for small gaps that are just cosmetic, but a failed shower or bath seal shouldn’t wait. We work on windows & doors, plot handovers and kitchens, and common reasons people get in touch are gaps between new skirting and floors and shower seals failing in the first year or two.
Work in a place like Hermiston is planned ahead, journey included. Outdoor plot mastic needs dry weather, but indoor floor and skirting joints can be sealed whatever the forecast.
There’s a 12-month guarantee on every job.

Signs you need new build mastic in Hermiston
When the heating goes on in the first winter, the house dries fast. Skirting, frames and worktops pull away slightly and cracks appear in the sealant.
If you can see any of these, it’s time to have the joints looked at:
- Leaking shower tray seals in a new home
- Cracked caulk along new skirting
- Worktop and upstand sealant coming away
- Untidy sealant flagged on a snagging list
In and around Hermiston, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.
What your quote should include
- How much experience the applicator has
- How the joint is cleaned and prepared
- The length of the guarantee
- What happens if they find a problem under the old sealant
How to look after the new joints
Aftercare is simple, and it makes a real difference:
- Resist patching a failed seal with a tube from the DIY shop
- Watch for new gaps as the house dries out
- Keep pictures and emails about snagging items
- Follow the cure time we give you
Photograph failed sealant before it’s redone and keep the builder’s replies. It helps if anything else comes up during the warranty period.
Report failed sealant to the builder while you are in the snagging period. Once it ends, the repair may be down to you.
Your questions about new build mastic in Hermiston
Do you cover Hermiston for new build mastic?
Yes, Hermiston is within the area we cover. Our work covers the whole of Scotland. Just send an email to info@mrmastic.co.uk with a few details of the job.
Do you cover smaller places like Hermiston?
Yes, Hermiston is covered. Our work covers the whole of Scotland, from towns to the smallest places. Longer journeys are simply planned in advance.
How long does new build mastic take?
As a guide, most jobs take a few hours for most snagging lists, longer for a run of plots. Bigger jobs take longer, and we’ll say how long yours will take.
Do you take on second-fix sealing for builders?
Yes. We work through plots to your schedule, room by room. Get in touch with the number of plots and the scope and we’ll quote.
Do you take out the old sealant first?
Yes. Sealing over the old bead is the commonest cause of early failure, and it’s something we never do.
Can you reseal over the builder’s sealant?
No. Over-sealing traps mould and water and soon fails. All the old sealant comes out before any work starts.
Should I wait before resealing?
Where water is getting through, do not wait. Hairline cosmetic gaps can wait until the house has settled.
Will it make a mess?
Tidy work is part of the job. We protect what’s around the joints, and the area is left clean when we finish.
How the visit works
There’s no need to move everything out, only the area right around the joints. Everything nearby is protected, and the work takes a few hours for most snagging lists, longer for a run of plots for a typical job. Around Hermiston, distance and access matter more than parking. Let us know how to find you and how to reach the joints, and the visit is planned around that.
- We go through the snagging list or plot schedule and agree the joints to do.
- 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.
- Finally, each room is checked and you are given the cure time.
Preparing for the visit
- Let us know about stairs, lifts or work at height
- Mention if the joints have been sealed before
- Mention any leaks or damp you’ve noticed
Getting a quote
It all starts with a short chat. Describe the problem, the location and the size of the job. Whenever you’re ready, drop us a line at info@mrmastic.co.uk.

New build mastic in Hermiston: local notes

What affects the quote in Hermiston

What we cannot put right
Sealant is not the answer to every problem, and we’d rather say so up front. It won’t solve:
- Your warranty claim itself, which is between you and the builder
- Leaking fittings rather than failed sealant
- Settlement cracks that need a surveyor
Not sure which it is? You can drop us a line at info@mrmastic.co.uk and we’ll tell you honestly.
Surfaces we seal
- Bathrooms & en suites
- Show homes
- Windows & doors
- Kitchens
- Skirting & floors
- Plot handovers
Landlords, agents and businesses in Hermiston
Water getting past a failed joint can damage the building, which is a bigger problem in a rented property. Resealing at the right time is simple maintenance that we can handle for you.
We regularly work with letting and managing agents. Tell us the address, the job and how access works.
DIY versus a professional finish
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.
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.
