When to call us in Broxburn
On many sites, sealant goes on in the final rush before handover. Dusty, unprimed joints are common, and the sealant sits on grit instead of the surface.
Signs it’s time to call us include:
- Shower seals failing in the first year or two
- Messy sealant that spoils new finishes
- Internal frame sealant that has split
- Skirting joints opening in the first winter
If you’ve bought a new home near Dunbar station, the sealant around baths, showers and frames is worth checking in the first year or two.

What happens on the day
Every visit runs the same way: we check the joints, protect the area around them, carry out the job and clear up. Most jobs take a few hours in a single home. Outdoor work around Broxburn depends on the weather, as sealant needs a dry surface, so external jobs may need to move if the day turns wet. Work indoors isn’t affected.
- First we work through your snagging list or plot schedule with you.
- 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.
- We check every joint and tell you how long each needs to cure.
Preparing for the visit
- For indoor joints, keep the area dry beforehand if you can

How we quote for new build mastic
You will get a clear quote before we start. It takes into account:
- The amount of work
- Working hours on commercial sites
- Access and height
- The type of sealant required
Leaving a failed joint normally makes the job bigger, not smaller. If you’re not sure whether it needs doing, send an email to info@mrmastic.co.uk for an honest opinion and a quote.
Asking for a quote
Before you ask for a quote, have a think about:
- The address or postcode of the job
- Photos by email, if that is easy
- Any previous sealing or DIY work
- The rough size of the job
If you’re in Broxburn and need new build mastic, drop us a line at info@mrmastic.co.uk. Tell us what the problem is and where, and we will agree the price before any work begins.
Keeping the joints in good condition
Joint life depends on how it’s used and looked after. Here’s what we suggest:
- Avoid running a DIY bead over the old one
- Wipe joints with warm soapy water
- Check bath and shower seals every few months as the house settles
- Put sealant faults on your snagging list early
Wipe the sealant with warm soapy water. Keep scourers and harsh chemicals off it.
A failed seal in a new home lets water into joists, plasterboard and ceilings. Early resealing keeps the job small and protects the rest of the house.
Questions from Broxburn
Do you work for landlords with property near Dunbar station?
Yes, landlords and agents are among the people we work for. You can email us at info@mrmastic.co.uk with the details for a clear quote.

Do you work for developers?
Yes. We carry out plot mastic and second-fix sealing for builders and developers. Send the schedule and any specification and we will give you a quote.
What do you need from me for a quote?
A short description and the location, with photos by email if possible. If we need more, we’ll ask.
Should I wait before resealing?
Any seal that is leaking should be redone right away. Cosmetic gaps can wait until the first year or two of movement has passed.
Do you use white or clear sealant?
We use white, clear or a colour to suit the finishes. Let us know your preference when you ask for a quote.
Will you just run a new bead over the existing one?
No. Sealing over old sealant looks fine for a few weeks, then lifts. We remove every bit of the old bead before resealing.
Why does sealant fail so quickly in new builds?
Cracking in the first couple of years is common as timber and plaster dry out. Rushed application on dusty surfaces makes it worse.
Should I try it myself first?
If you’ve already had a go yourself, that’s fine. We cut it out and start again, so just mention it when you contact us.
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and doesn’t move well, and getting the depth right matters as much as the look.
