New build mastic in Church Street, done properly
Snagging sealant properly means taking the failed bead out completely. New silicone will not bond to old silicone, so it all comes out before we clean, dry and reseal. We work on windows & doors, plot handovers and skirting & floors, and common reasons people get in touch are cracked sealant around new window and door frames and gaps between new skirting and floors.
Around Church Street, older homes often have timber floors that move through the year, which is why skirting and threshold joints need a flexible sealant, not filler.
Big or small, it’s backed by our 12-month guarantee.

Signs you need new build mastic in Church Street
The wrong product is sometimes used in the wrong place: decorators’ caulk in a wet area, or a stiff sealant where there’s movement. Neither lasts long.
The most common problems we see are:
- Messy sealant that spoils new finishes
- Cracked sealant around new window and door frames
- Gaps behind new kitchen upstands
- Cracks appearing as a new home settles
If you’ve bought a new home near Higham station, the sealant around baths, showers and frames is worth checking in the first year or two.

FAQs for Church Street
Do you work for landlords with property near Higham station?
Yes, rental work is part of what we do. You can ring 0345 464 0079 or drop us an email with the address and a few details, and we’ll give you a fixed price before we start.
Will you come out to Church Street?
Yes, Church Street is covered. Our work covers London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.
What should I tell you?
Tell us what needs doing and where, plus pictures if you have them. We will ask anything else we need to know.
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.
Can you reseal over the builder’s sealant?
No. Over-sealing traps mould and water and soon fails. We remove every bit of the old bead before resealing.
Do you guarantee your work?
Yes, for a year. If anything is not right with the work within the year, let us know and we’ll sort it.
What sealant do you use?
Products from Arbo and Everbuild, among others, chosen to suit the joint. We explain the product when we quote.
Is there any odour?
That depends on the sealant. Some smell for a while, some hardly at all, and any smell fades as they cure.
What happens on the day
When we get to you, we check the joints match what you told us. If anything is different, we explain it before carrying on. After that, the work takes anything from a few hours to several days, depending on the number of plots. Somewhere like Church Street 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, with no layer left behind.
- Joints are vacuumed and cleaned of building dust.
- 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.
Getting ready for the visit
- Let us know about stairs, lifts or work at height
- Keep pets and children clear of the area while we work
- For indoor joints, keep the area dry beforehand if you can

New homes and floors in Church Street
Church Street is close to the coast. New homes near the sea put their outside mastic to work from day one, so it’s worth checking at snagging. The South East is one of the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
Around Church Street, as everywhere, new build mastic is only as good as the preparation behind it.

Keeping the joints in good condition
Good habits help new joints last longer. Our tips:
- Put sealant faults on your snagging list early
- Wipe joints with warm soapy water
- Look at the sealant regularly in the first couple of years
- Resist patching a failed seal with a tube from the DIY shop
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. Resealing before mould gets in saves a harder job later.

Leave it or put it right?
A failed shower or bath seal in a new home lets water into floors and walls that are still drying out. Resealing promptly protects the new finishes around it. Older cottages and farmhouses around Church Street can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
Rather than a set price list, we look at what your job involves: how many joints, what’s in them now and how we reach them. You’ll know the price before we begin.
