New build mastic in Temple: local notes
Much of London’s new housing is flats in larger developments, where snags may need reporting through the developer or the managing agent. Compared with the north and west, the South East gets less rain, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
For new homes near London Blackfriars station, it’s worth checking the sealant early, while snags are still fresh.

New build mastic in Temple, done properly
For builders and developers, we work through plots to the schedule you give us. We seal bathrooms, kitchens, windows, doors and skirting so plots are ready to hand over. We work on kitchens, skirting & floors and windows & doors, and people most often call us about internal frame sealant that has split and gaps opening as the house dries out and settles.
Much of London’s new housing is flats in larger developments. Snagging there often goes through the developer or managing agent, and failed shower seals, open skirting joints and gaps at thresholds are typical.
The work is guaranteed for twelve months. If there’s a problem with our work within the year, let us know and we will sort it.

Keeping the joints in good condition
Joint life depends on how it’s used and looked after. We suggest:
- Report sealant problems to your builder during the snagging period
- Photograph failed sealant before it’s redone
- Don’t wait for the house to settle if water is getting through
- Watch for new gaps as the house dries out
Ventilation matters in a new home, which is still drying out. Use the extractor fan or open a window after showers to help keep mould away.
A failed seal in a new home lets water into joists, plasterboard and ceilings. Early resealing keeps the job small.
Common problems we fix in Temple
Fresh sealant can be knocked or cut by trades finishing off. A bead disturbed before it has cured may never seal properly, and the problem shows up after you move in.
People normally contact us when they notice one of these:
- Untidy sealant flagged on a snagging list
- Plot mastic for developers ahead of handover
- Gaps opening as the house dries out and settles
- Shower seals failing in the first year or two
Temple is in London, so parking needs planning: let us know about parking bays, permits or a driveway.
Questions to ask before booking
- Whether they seal over old material or remove it
- How long to leave it before use
- Who turns up on the day
- What happens if the job turns out different
What sealant work cannot fix
In fairness, there are a few things sealant will not fix:
- Disputes or warranty claims with your builder
- Cracking that points to a structural problem
- Leaking fittings rather than failed sealant
If in doubt, ring 0345 464 0079 or drop us an email and we will say what we think.
What we seal
- Bathrooms & en suites
- Kitchens

The process
The work is kept neat and contained to the joints we are treating, so you can get on with your day. Expect the work to take a few hours for most snagging lists, longer for a run of plots, and we tell you how long to leave it before we go. For a job in Temple, parking and access are the things to plan: tell us about permits, visitor bays or off-street space, which floor we’re working on and whether there’s a lift.
- Each joint is checked for movement before we start.
- We remove the failed sealant and clean the joints.
- Joints are dried and primed where the product calls for it.
- Baths are filled with water, then the new sealant is applied.
- We check every joint and leave you with the cure times.
How to prepare
- Tell us if parking is tricky
- Let us know if you’ve seen damp or leaks
- Where the joints are inside, avoid wetting them before we arrive

Advice
Common questions in Temple
Do you work for landlords with property near London Blackfriars station?
Yes, rental work is part of what we do. Just phone 0345 464 0079 or drop us an email and tell us about the property, and we’ll send you a clear quote.
Is parking an issue for new build mastic in Temple?
London parking needs a little planning, so let us know about permits, bays or a driveway when you book. That way the visit can be planned around it.
Do you hold any approvals?
Yes. Mr Mastic is an ARBOMaster approved applicator.
Where is Mr Mastic based?
Mr Mastic is based in Crawley. We cover Temple and the rest of Greater London.
Is the work guaranteed?
Yes, always. There’s a 12-month guarantee on every job, large or small.
Is it worth resealing while the house is still settling?
That depends on the joint. A leaking shower or bath seal should be redone right away, while small cosmetic gaps can wait a while.
Should I try DIY first?
For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. The usual mistakes are sealing over old sealant, sealing a damp joint and using too much.
Do you use white or clear sealant?
That depends on what the joint meets: white or clear in most bathrooms, and a colour to suit worktops, frames and floors elsewhere. We will agree it with you first.
Landlord and commercial work in Temple
We also work for businesses, from offices to washrooms and kitchens. For commercial premises, we can talk through working times when we quote.
Hotels need rooms back in use, so the work can be planned room by room. Hotel work is part of what we do, alongside homes and businesses.
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 most come down to preparation. In a London flat, a failed joint rarely stays your problem alone: water from a shower or window joint can reach the flat below, and gaps in fire-stopping matter to everyone in the building.
Commercial jobs are quoted on the same basis as homes: the amount of work, how we reach it and what it needs, plus any working-time requirements on site. Ask us for a quote and we will go through it with you.
What you get with us
- White, clear, grey or coloured to suit, where the product allows
- Sanitary silicone with an anti-fungal additive in wet areas
- 20+ years of sealant experience
- ARBOMaster approved applicator

What affects the quote in Temple
Some jobs are bigger than they look, and some smaller. The main factors:
- Working hours on commercial sites
- How easy the joints are to reach
- The product the joint needs
- The size of the job
What it costs depends on the size of the job, how hard the old material is to remove and access to the work. You will have a clear quote before any work starts, so you know where you stand.
What we need to know
Photos help, but a description is a good start. Try to tell us:
- Pictures of the joints, sent by email
- Whether it has been sealed before
- The problem you’ve noticed
- The type of property
