Stranraer questions
Can you help a landlord with a rental near Stranraer station?
Yes. We work for letting agents and landlords 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 Stranraer for new build mastic?
Yes. Our work covers the whole of Scotland, and Stranraer is part of that. Just send an email to info@mrmastic.co.uk with a few details of the job, and we’ll give you a clear price.
Do you use white or clear sealant?
It depends on the joint: white or clear in most bathrooms, and a colour to suit worktops, frames and floors elsewhere. We agree the colour before we start.
Can I send you my snagging list?
Yes. We often work straight from a snagging list. We’ll go through the sealant items and agree what we will do.
Will it make a mess?
Not at all. We work neatly, protect the area around the joints and tidy up afterwards.
Do the sealants smell?
That depends on the sealant. Some smell for a while, some hardly at all.
Where do you work from?
Our base is Crawley, with over 20 years’ experience. We work across South East England, London and Scotland.
Should I wait before resealing?
Any seal that is leaking should be redone right away. For small cosmetic gaps, waiting until the house has settled can save doing them twice.
About our new build mastic in Stranraer
If your new home has a leaking shower seal, open skirting joints or untidy sealant, we can help. While the builder’s snagging or warranty period runs, report it to them first, and if it isn’t put right, get in touch with us. We work on show homes, skirting & floors and plot handovers, and common reasons people get in touch are gaps opening as the house dries out and settles and shower seals failing in the first year or two.
Scottish towns like Stranraer have older streets and newer estates, with new homes still being built in many. New homes need their sealant and floor joints finished properly, and older ones need them renewing.
Big or small, you get the same 12-month guarantee.

Joints and finishes in Stranraer homes
Stranraer is close to the coast. New homes near the sea put their outside mastic to work from day one, so any gaps are best picked up early. Stranraer is in the west of Scotland, which is wetter than the east, which means plot mastic and the sealant in new homes has to cope with a lot of rain.
For new homes near Stranraer station, it’s worth checking the sealant early, while snags are still fresh. In and around Stranraer, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.

Surface by surface
Bathrooms and en suites
Baths, showers, basins and trays in new bathrooms are the most common new-build reseal. We cut out the failed bead, clean and prime, and reseal with anti-fungal sanitary silicone.
Plot handovers
Good preparation at handover saves snagging later. We clean out building dust before sealing and primer used where needed.
The process
Before we leave, we go over the finished joints with you and explain the cure time. The work normally takes a few hours for most snagging lists, longer for a run of plots, depending on how much there is to do. In a Scottish town like Stranraer, parking is normally straightforward, though older centres can be tighter. If you are in a flat with a shared stair or a door entry system, let us know when you book.
- First, the list of joints is agreed from your snagging sheet or plot schedule.
- The failed sealant is removed completely.
- We clean out the dust and grit left from the build.
- We prime where needed and apply a sealant suited to each joint.
- We tool every joint neatly and tell you when each area can be used.
Before we arrive
- Mention any tricky access
- Tell us about any previous sealing or DIY attempts
- Tell us if parking is tricky

Advice
Why deal with it now?
A quick bead over the top of the old sealant can look fine at first, but it will not bond to the old layer. Taking it all out and starting again is the only way to get a lasting seal. In flats with a shared stair in Stranraer, a leak from a failed seal can affect the flat below too, and that’s much harder to put right.
What you pay reflects the work, not guesswork. That’s why we ask a few questions first and agree the price before starting.
Why Stranraer clients choose us
- Anti-fungal sanitary silicone in wet areas
- 20+ years of sealant experience
- Fully insured
- Any old sealant cut out fully, not covered over
DIY sealant or a professional job?
A DIY attempt doesn’t rule out a professional job. We remove it and do the joint properly, so tell us about it when you ask for a quote.
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
When it is not the sealant
New sealant cannot fix everything, and we will tell you before any work starts. It will not solve:
- Structural cracks in walls or ceilings
- A tray or bath that is not properly supported, until it’s fixed
- Leaks from pipes, valves or wastes, which need a plumber
If in doubt, email us at info@mrmastic.co.uk and we’ll say what we think before you book.
