Why act early in Speed Gate
Sealant done properly at handover means fewer callbacks. Every return visit for a failed seal takes time, and they’re avoidable with good preparation. Around Speed Gate, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
A failed joint rarely gets cheaper to fix by waiting. If you’re unsure, ring 0345 464 0079 or send us an email for an honest opinion and a quote.

Landlord and commercial work in Speed Gate
Mouldy or split sealant often shows up at the end of a tenancy, and it’s easy to sort out between tenants. Several properties can be quoted together.
Hotels need rooms back in use, so the work can be planned room by room around your bookings where we can. We’ve worked in hotels as well as homes and businesses.
Can I do it myself?
A DIY attempt does not rule out a professional job. We remove it and do the joint properly, so just mention it when you contact us.
Some sealant jobs are within reach of a careful DIYer, 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.
How to look after the new joints
To keep the joints looking good and working properly:
- Avoid scourers and strong chemicals on sealant
- Report sealant problems to your builder during the snagging period
- Check bath and shower seals every few months as the house settles
- Wait for the cure time before using a resealed shower
Clean the sealant with a mild detergent and a soft cloth. Keep scourers and harsh chemicals off it.
Lifting sealant traps moisture and mould behind it. Dealing with it before it goes black keeps the job straightforward.
New homes and floors in Speed Gate
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.
For new homes near Longfield station, it’s worth checking the sealant early, while snags are still fresh.

How the visit works
Good joint work is mostly preparation, so that’s where we spend the time. Joints are cleaned back and dried before anything new goes in. All told, the work takes a few hours in a single home. In a small place like Speed Gate, access is normally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- First, the list of joints is agreed from your snagging sheet or plot schedule.
- Every bit of the old builder’s sealant is cut out, 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.
- Each bead is tooled and the cure times explained.
How to prepare
- Tell us about access, such as stairs, a lift or high-level joints
- Plan for the work area to be out of bounds to pets and children
- Move anything stored near the joints

Advice
What we’re called out for in Speed Gate
Baths and trays settle under load once the home is lived in. A bath sealed empty drops slightly when filled, straining the joint and can tear.
The problems people generally mention when they call are:
- Untidy sealant flagged on a snagging list
- Worktop and upstand sealant coming away
- Beads laid onto grit and dust from the build
- Gaps between new skirting and floors
In and around Speed Gate, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.

Common questions in Speed Gate
Can you do new build mastic in Speed Gate?
Yes. We work across London and the South East, and Speed Gate is part of that. You can ring 0345 464 0079 or send us an email and let us know what needs doing.
Do you cover smaller places like Speed Gate?
Yes, smaller places are covered as well as towns. Our work covers London and the South East. Just mention lanes, gates or anything else about the route when you book.
Are you an approved applicator?
Yes. We are an ARBOMaster approved applicator, which is run for the Arbo sealant brand.
Will you just run a new bead over the existing one?
No. We always remove the existing bead, then clean and prime the joint, before resealing.
Is it messy?
We keep the work tidy. Nearby surfaces are protected, and the area is left clean when we finish.
What does new build mastic cost?
We don’t publish prices, because the cost depends on the job: how much there is, what’s there now, how we reach it and what it needs. You will get a clear quote before we start.
Do you take on second-fix sealing for builders?
Yes. We take on second-fix sealant work across new plots. Good preparation keeps snagging to a minimum.
Is it worth resealing while the house is still settling?
It depends on whether water is getting through. A leaking shower or bath seal should be redone straight away, but cosmetic gaps can wait for movement to slow.
What affects the cost of new build mastic
We quote each job individually. These are the things that affect it:
- Whether there’s mould to deal with
- How many rooms, windows or areas are involved
- Access and height
- How much old sealant there is and how hard it is to remove
The cost depends on the amount of work, how much old material has to come out and access to the work. We give a clear quote before any work starts, so you know where you stand.
Helping us quote
To make quoting easier, let us know:
- Whether it has been sealed before
- Photos by email, if that’s easy
- The rough size of the job
- Any access issues, like height or stairs
A good description makes for an accurate quote. Tell us where the job is, what’s wrong and how much there is, and email pictures if that’s easy.
