New build mastic for homes and businesses in Upper Largo
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. If you have worktop and upstand sealant coming away and joints pulling apart as timber shrinks, we can help, on bathrooms & en suites, windows & doors and show homes alike.
For a place like Upper Largo, 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.
You are covered for a year from the day we finish. If there’s a problem with it, please drop us a line at info@mrmastic.co.uk.

DIY versus a professional finish
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions, then guaranteed for a year.
What affects the cost of new build mastic
You will get a clear quote before work begins. It’s based on:
- Mould in or behind the old joints
- Working hours on commercial sites
- How many areas need sealing
- Which sealant suits the joint
The cost reflects the work involved, not a rough estimate. That’s why we ask a few questions first.
What to tell us for a quote
The more you tell us, the more accurate the quote. When you get in contact, it helps to mention:
- Whether it has been sealed before
- The rough size of the job
- Any access issues, like height or stairs
- Photos by email, if that’s easy
Asking for a quote is easy: let us know what needs doing and where and its rough size. A few pictures by email make the job easier to understand, and we’ll come back to you with a quote.

What we can’t put right
Honest advice matters more to us than a booking, so here’s what new sealant will not do:
- Your warranty claim itself, which is between you and the builder
- Settlement cracks that need a surveyor
- Baths and trays that move too much for sealant to cope with
Not sure which it is? You can drop us a line at info@mrmastic.co.uk and we’ll tell you honestly before you book.

What new build mastic looks like in Upper Largo
Upper Largo is close to the coast. Plot mastic on new homes near the coast takes more weather than it would inland, so it’s worth checking at snagging. Timber frame is common in newer Scottish homes, and as the frame dries and settles, skirting and sealant joints can open up.
For new homes near Leven station, it’s worth checking the sealant early, while snags are still fresh. In and around Upper Largo, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.

Surface by surface
Plot handovers
Good preparation at handover saves snagging later. Dust from the build is removed first and primer used where needed.
Windows and doors
The gap between a new frame and its plaster reveal often opens up. We remove cracked sealant and apply a flexible one that suits the frame.
Leave it or put it right?
A quick bead over the top of the old sealant can look fine at first, but it cannot bond to what’s underneath. A lasting seal starts with removing the old one completely. Around Upper Largo, water from a failed joint in an older stone home can soak into timber and plaster, which is a far bigger job than the sealant.

Your questions about new build mastic in Upper Largo
Do you work for landlords with property near Leven station?
Yes. We work for landlords and letting agents as well as homeowners, and several properties can go on one quote. You can drop us a line at info@mrmastic.co.uk with the details for a clear quote.
Do you cover smaller places like Upper Largo?
Yes, we do. We work across all of Scotland, from towns to the smallest places. Longer journeys are simply planned in advance.
How long should I leave it?
Different products cure at different speeds, so please follow the time we give you when we finish.
Do you work for developers?
Yes. We seal plots to the developer’s programme, room by room. Get in touch with the number of plots and the scope and we will quote.
Will it make a mess?
We keep the work tidy. We protect what’s around the joints.
Will you just run a new bead over the existing one?
No. Over-sealing traps mould and water and soon fails. All the old sealant comes out before work begins.
Do you take out the old sealant first?
Always. Sealing over old sealant is the main reason resealing fails early, and it’s something we never do.
Is there any odour?
That depends on the sealant. Some smell for a while, some hardly at all, and any smell fades as they cure.
How the visit works
You do not need to clear the whole room or building, only the area right around the joints. We protect the rest, and the work takes a few hours in a single home for a typical job. Around Upper Largo, distance and access matter more than parking. Tell us how to find the property and how to reach the work, and the visit is planned around that.
- First we work through your snagging list or plot schedule with you.
- The old bead comes out in full, with no layer left behind.
- We clean off dust from the build and prime the surfaces where the product needs it.
- A sealant chosen for each area goes in and is tooled smooth.
- Finally, each room is checked and you’re given the cure time.
How to prepare
- Tell us about any previous sealing or DIY attempts
- Move anything stored near the joints
- Where the joints are inside, avoid wetting them before we arrive
