How to look after the new joints
Joint life depends on how it’s used and looked after. We suggest:
- Open a window or run the fan after bathing
- Put sealant faults on your snagging list early
- Clean sealant with mild detergent, not abrasives
- Get a leaking seal dealt with right away
Watch the joints as the house settles. Small gaps can appear as the house dries, and they’re simple to reseal once movement has slowed.
Do not let the snagging period run out with sealant problems unreported. After that, putting it right may fall to you, so raise it early.
New build mastic in Crawford, done properly
In a new home, every joint should have a clean, even bead. Smeared, patchy or cracked sealant is worth sorting early, before water reaches anything behind it. If you are dealing with cracks appearing as a new home settles and new-build shower sealant that has already split, we can help, on kitchens, show homes and windows & doors alike.
Many newer homes in Scotland are timber-framed and settle as they dry out, so skirting and floor joints can open up. In older homes, timber floors move through the year too.
A one-year guarantee comes as standard, so you’re not left on your own once the job is done.

Quotes for new build mastic in Crawford
There’s no set price list, because jobs vary so much. What we look at:
- The type of sealant required
- Whether old sealant or filler has to be cut out
- Any working-time requirements on site
- Access and height
Leaving a failed joint normally makes the job bigger, not smaller, as water and mould keep getting in. If you are unsure, drop us a line at info@mrmastic.co.uk and we will give you an honest view and a quote.
What we need to know
Photos by email are helpful but not essential. Please mention:
- The type of property
- Roughly how big the job is
- What the problem is, such as mould, gaps, leaks or cracking
- Where the property is
We quote each job on its own, so the first step is telling us about yours. Just send an email to info@mrmastic.co.uk with the details.
Crawford questions
Will you come out to Crawford?
Yes, Crawford is covered. Our work covers the whole of Scotland, from towns to the smallest places. Longer journeys are simply planned in advance.
Is there a guarantee on new build mastic in Crawford?
Every job comes with our one-year guarantee, wherever it is. We’re fully insured, and an ARBOMaster approved applicator.
Can you work from my snagging list?
Yes. Photos of each sealant item help us quote. If something isn’t sealant, we’ll say so.
Can I do it myself?
It depends on the job. High-level, external movement and fire-rated joints are professional jobs.
Is it worth resealing while the house is still settling?
It depends on whether water is getting through. Failed seals in wet areas need doing now, but cosmetic gaps can wait for movement to slow.
Do you hold any approvals?
Yes. ARBOMaster is the approved applicator scheme for Arbo sealants, and we’re part of it.
How long before the joint can be used?
Different products cure at different speeds, so follow the cure time we give you.
Can you match the sealant colour to my new kitchen or bathroom?
That depends on what the joint meets: white or clear in most bathrooms, and a colour to suit worktops, frames and floors elsewhere. We agree the colour before any work starts.
When something else is needed
A few problems are outside what sealant work can do:
- Structural cracks in walls or ceilings
- Leaking fittings rather than failed sealant
- A tray or bath that isn’t properly supported, until it’s fixed
Not sure which it is? You can drop us a line at info@mrmastic.co.uk and we will tell you honestly before booking.

DIY versus a professional finish
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, and the work is guaranteed for a year.
Some sealant jobs are within reach of a careful DIYer, 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.
What happens if it’s left?
Sealant done properly at handover means fewer callbacks. Snagging visits for failed sealant cost time on every plot and most come down to preparation. Out of town in Scotland, exposed walls take a lot of weather, and once water gets behind a failed joint, damp in stone or harled walls is slow to dry out.
Commercial jobs are quoted on the same basis as homes: the amount of work, the access and the products needed, plus any working-time requirements on site. Call for a quick quote and we will go through it with you.

What else we do in Crawford
What we do, step by step
We bring everything the job needs with us. After a quick look at the joints together, we protect the area and start. Most jobs take a few hours in a single home. Outside jobs in Crawford 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 is not affected.
- 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.
- We check every joint and tell you how long each needs to cure.
How to prepare
- Where the joints are inside, avoid wetting them before we arrive
- Clear items away from the joints we’re working on
- Let us know if you’ve seen damp or leaks

Asking for a quote is easy: let us know the job and the location. A few pictures by email make the job easier to understand, and we’ll take it from there.
