Why it’s worth doing now in Titmore Green
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. Around Titmore Green, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
A few things move the cost up or down: the old material and how easily it comes out, whether mould needs treating, and whether the work is at height. We take all of that into account in your quote.

New build mastic for homes and businesses in Titmore Green
Our new-build work comes in two parts: plot mastic for developers, and putting right failed sealant for people who’ve bought a new home. Both get the same care over preparation. If you’re dealing with messy sealant that spoils new finishes and plot mastic for developers ahead of handover, we can put it right.
Somewhere as small as Titmore Green, new homes tend to be conversions, self-builds or a few houses rather than an estate. Each still needs its sealant and floor joints finished properly.
You get a 12-month guarantee, the same in Titmore Green as everywhere else we work.

DIY versus a professional finish
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and doesn’t move well, and the joint depth matters as much as the finish.
New build mastic around Titmore Green
Compared with the north and west, the South East gets less rain, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
In and around Titmore Green, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint. If you’ve bought a new home near Stevenage station, the sealant around baths, showers and frames is worth checking in the first year or two.

Common questions in Titmore Green
Do you cover smaller places like Titmore Green?
Yes, we do. We work across London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
I let a flat near Stevenage station. Can you help?
Yes, rental work is part of what we do. You can call 0345 464 0079 or send us an email with the address and a few details, and we’ll give you a fixed price before any work starts.
Do I need to be at home?
That depends on where the joints are. For work indoors, someone needs to let us in, while outside work can sometimes be arranged differently.
Will there be a smell?
Some sealants have a smell while they cure. Ventilation helps.
Are you an approved applicator?
Yes. We’re approved under the ARBOMaster scheme, the approved applicator scheme for Arbo sealants.
Do you work through snagging lists?
Yes. Send us the sealant items on the list, with photos if you can. We’ll tell you if anything on it isn’t a sealant job.
Is it normal for sealant to crack in a new home?
New homes dry out and move in their first couple of years, and sealant is often applied quickly onto dusty surfaces. Both lead to early failure.
Can you work on commercial sites?
Yes, regularly. Larger jobs can be planned room by room or area by area.
Surface by surface
Windows and doors
The gap between a new frame and its plaster reveal often opens up. We cut out the cracked bead and reseal with a flexible sealant in a matching colour.
Plot handovers
Plot mastic is carried out to the developer’s schedule. Each joint is cleaned and primed where needed so the sealant lasts.
Aftercare tips
Once the sealant has cured, a few habits help it last:
- Raise failed sealant with the developer while you are covered
- Watch for new gaps as the house dries out
- Do not wait for the house to settle if water is getting through
- Avoid scourers and strong chemicals on sealant
Don’t stand on the bath edge or the lip of the tray in the first few weeks. If a bath or tray moves when you stand in it, get it looked at.
Lifting sealant traps moisture and mould behind it. Dealing with it before it goes black saves a harder job later.
How it works
At the end, we look at the finished work together and tell you how long to leave it. The visit itself generally takes a few hours for most snagging lists, longer for a run of plots, depending on the size of the job. Somewhere like Titmore Green needs a little journey planning: let us know about lanes, gates and parking. We bring what the job needs, so it can be finished in one trip where possible.
- 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.
- Primer goes on where the surface and product need it, then the new sealant.
- We tool every joint neatly and tell you when each area can be used.
Getting ready for the visit
- Keep pets and children clear of the area while we work
- Try not to wet indoor joints just before the visit
- Let us know about parking restrictions
