How we quote for new build mastic

- The number of rooms or windows
- The amount of work
- Any mould that needs treating
Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, whether mould needs treating, and whether the work is at height. We take all of that into account in your quote.
Asking for a quote
When you call or email, these details help:
- Any previous sealing or DIY work
- Whether it’s a home or a business
- What the problem is, such as mould, gaps, leaks or cracking
- The address or postcode of the job
It all starts with a short chat. Tell us what’s wrong, where it is and how much there is, and we’ll explain how we’d tackle it. When it suits you, send an email to info@mrmastic.co.uk.
About our new build mastic in Southend
Some owners wait for the first year’s movement before having joints redone. That makes sense for small gaps that are just cosmetic, but a seal that’s letting water through needs doing now. We work on windows & doors, plot handovers and kitchens, and common reasons people get in touch are sealant that never bonded to the surface and plot mastic for developers ahead of handover.
New homes in smaller Scottish places are often single plots, self-builds or small developments. Each needs its sealant and floor joints finished as carefully as on a big site.
Each job carries a 12-month guarantee.

What else we do in Southend
Do you need new build mastic in Southend?
When the heating goes on in the first winter, the house dries fast. Skirting, frames and worktops pull away slightly.
Any of these means the joints need attention:
- Beads laid onto grit and dust from the build
- Leaking shower tray seals in a new home
- Kitchen sealant that has pulled off the wall
- Joints pulling apart as timber shrinks
For jobs in and around Southend, choosing the right material for each joint is as important as a tidy finish.
Before booking anyone
- Whether they seal over old material or remove it
- Are they insured?
- What happens if they find a problem under the old sealant
- What the cure time is
Aftercare tips
To keep the joints looking good and working properly:
- Wipe joints with warm soapy water
- Record problems with dated photos
- Check bath and shower seals every few months as the house settles
- Put sealant faults on your snagging list early
Avoid standing on the rim of the bath or the edge of the tray while the sealant cures. If a bath or tray moves when you stand in it, get it looked at.
If a shower tray or bath seal splits in the first year, look for movement. Have it resealed, and the tray or bath checked, before it gets worse.
What we do, step by step
On the day, there’s very little for you to do. Point us to the joints and we will get on with it. The job generally takes a few hours in a single home, including the tidy-up. For a place like Southend, longer drives are planned in advance. Mention tracks, gates, ferries or anything else about the route.
- We start by agreeing which joints are on the list, from the snagging sheet or plot schedule.
- Failed or untidy sealant is cut out completely.
- 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.
- Each area is checked and left with its cure time.
How to prepare
- Tell us about any previous sealing or DIY attempts
- Let us know if you’ve seen damp or leaks
- Clear items away from the joints we’re working on

Leave it or put it right?
Sealant done properly at handover means fewer callbacks. Snagging visits for failed sealant cost time on every plot, and they’re avoidable with good preparation. In an older home around Southend, damp from a failed joint can get into timber and plaster, which is a far bigger job than the sealant.
Combining jobs into one visit is generally more efficient than separate visits, so it’s worth mentioning everything you’d like done. You’ll get one clear quote for the whole job.

Southend questions
Will you come out to Southend?
Yes, Southend is covered. Our work covers the whole of Scotland, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
Is new build mastic in Southend guaranteed?
Every job comes with our one-year guarantee, wherever it is. We are fully insured, and an ARBOMaster approved applicator.
Can new sealant go on top of the old bead?
No. Over-sealing traps mould and water and soon fails. All the old sealant comes out before any work starts.
Are you an approved applicator?
Yes. We are ARBOMaster approved, the scheme for applicators of Arbo sealants.
Can you quote for more than one area?
Yes. Several rooms, windows or areas can go on one quote.
When is the sealant fully cured?
It depends on the product and the temperature. We tell you how long to leave it before we go.
What information do you need?
Where the job is, what the problem is and roughly how big it is. If you can, email a few pictures.
Which products do you use?
It depends on the joint: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. Brands we use include Arbo and Everbuild.
For landlords and businesses
We also work for businesses, from offices to washrooms and kitchens. On commercial sites, working times can be discussed when we quote.
Landlords and agents in Southend can book us as well as homeowners. Resealing between tenancies is a simple way to keep a property in good order.
Joints and finishes in Southend homes
Southend 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. Many new homes in Scotland are timber-framed, so skirting and sealant joints can open up as the building settles.
Around Southend, as everywhere, new build mastic is only as good as the preparation behind it.
