I’m a tenant. Can you help?

When is the best time to reseal in a new build?

Do you work for landlords and businesses?

About our new build mastic in Lockerbie
Dust is the enemy of new-build sealant. We clean every joint thoroughly and prime where the surface and product need it, so the sealant actually sticks. Typical jobs include leaking shower tray seals in a new home and sealant that never bonded to the surface, across show homes, skirting & floors and windows & doors.
New homes in smaller Scottish places are often single plots, self-builds or small developments. They need their sealant and floor joints finished just as carefully as on a big site.
All of our work is guaranteed for twelve months, in Lockerbie and everywhere else we cover.

Surface by surface
Windows and doors
Internal joints between frames and plaster often crack as a new house dries. We cut out the cracked bead and reseal with a flexible sealant that suits the frame.
Bathrooms and en suites
Trays and baths in new builds settle as they’re used. We reseal once the old bead is fully out.
DIY versus a professional finish
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
If you are set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it does not work out, we can still put it right.
How it works
All our tools and materials come with us in the van, so you do not need to buy or prepare anything. After a quick look at the joints together, we protect the area and start. It normally takes a few hours in a single home. Around Lockerbie, distance and access matter more than parking. Let us know how to find you and how to reach the joints, and the visit is planned around that.
- We start by agreeing which joints are on the list, from the snagging sheet or plot schedule.
- The old bead comes out in full, with no layer left behind.
- Each joint is cleaned of dust and grit, then primed if required.
- We apply a sealant that suits each joint and tool it to a neat finish.
- Finally, each room is checked and you are given the cure time.
Getting ready for the visit
- Let us know about stairs, lifts or work at height
- On commercial sites, let us know about site rules
- Keep children and pets away from the work area

What else we do in Lockerbie
What affects the cost of new build mastic
The price is agreed before any work begins. It takes into account:
- How many rooms, windows or areas are involved
- The number and length of the joints
- Working hours on commercial sites
- How much old sealant there is and how hard it is to remove
Leaving a failed joint generally makes the job bigger, not smaller, because water and mould keep working on it. If you are not sure whether it needs doing, email us at 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:
- Where the property is
- Access, such as stairs, a lift or height
- If it’s domestic, commercial or a hotel
- What the problem is, such as mould, gaps, leaks or cracking
To get a quote, email us at info@mrmastic.co.uk and tell us where the job is and what the problem looks like. You will have a clear quote before we start.
Why it’s worth doing now in Lockerbie
A hairline gap at a skirting can wait, but a leaking seal cannot. Not sure whether yours can wait? You can email us at info@mrmastic.co.uk with a few photos and we will give you a straight answer. Around Lockerbie, 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.
No two jobs are quite the same, so we quote each one individually. Size, access and the product the joint needs all make a difference.
