DIY sealant or a professional job?
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
How we handle new build mastic in Cousland
We carry out plot mastic and second-fix sealing for builders, and snagging reseals for new-home owners. Both get the same care over preparation since hurried prep is behind a lot of new-build failures. Common call-outs are for smeared, uneven beads picked up at snagging and gaps behind new kitchen upstands, across skirting & floors, kitchens and show homes.
Work in a place like Cousland is planned ahead, journey included. Inside work goes ahead in any weather; outside mastic needs a dry day.
Every job comes with a one-year guarantee, wherever you are in Midlothian.

Quotes for new build mastic in Cousland
Every job gets its own quote. These are the things that affect it:
- The size of the job
- Working hours on commercial sites
- How much old sealant there is and how hard it is to remove
- Mould in or behind the old joints
Rather than a set price list, we price the job in front of us: the amount of work, the old material and the access. The price is agreed before we begin.
What we need to know
Before you ask for a quote, have a think about:
- What the problem is, such as mould, gaps, leaks or cracking
- Roughly how big the job is
- Any previous sealing or DIY work
- Where the job is, and your postcode
The more we know about the job, the more useful the quote. Let us know the location, the problem and roughly how many joints, and add pictures by email if you can.
How to look after the new joints
Good habits help new joints last longer. Our tips:
- Avoid scourers and strong chemicals on sealant
- Put sealant faults on your snagging list early
- Photograph failed sealant before it’s redone
- Use the extractor fan every time you shower
Clean the sealant with a mild detergent and a soft cloth. Keep scourers and harsh chemicals off it.
Early snagging is easier snagging. Left alone, a small crack can become a leak.

Do the sealants smell?

Advice
Do you need new build mastic in Cousland?
On many sites, sealant goes on in the final rush before handover. Joints aren’t always cleaned of dust or primed, and the sealant sits on grit instead of the surface.
It’s worth asking for a quote if you see:
- Worktop and upstand sealant coming away
- Messy sealant that spoils new finishes
- Plot mastic for developers ahead of handover
- Joints pulling apart as timber shrinks
If you’ve bought a new home near Wallyford station, the sealant around baths, showers and frames is worth checking in the first year or two.

How the job changes by surface
Plot handovers
Send us the schedule and any sealant specification. We seal bathrooms, kitchens, frames and floors as agreed.
Bathrooms and en suites
New-build bathrooms and en suites are where sealant fails most often. The old sealant comes out and anti-fungal sanitary silicone goes in after cleaning and priming.
Leave it or put it right?
It often makes sense to do all the sealant items on a snagging list together. You get one visit and one clear quote. Out of town in Scotland, exposed walls take a lot of weather, and damp in stone or harled walls takes a long time to dry once water gets behind a joint.
Commercial jobs are quoted on the same basis as homes: how much there is to do, how we reach it and what it needs, plus any working-time requirements on site. Call for a quick quote and we will explain what it covers.
