East Hanney questions
Do you cover East Hanney for new build mastic?
Yes, East Hanney is within the area we cover. We work across London and the South East. Just ring 0345 464 0079 or send us an email with a few details of the job.
Do you cover smaller places like East Hanney?
Yes, East Hanney is covered. We work across London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
Should I try DIY first?
It depends on the job. High-level, external movement and fire-rated joints are professional jobs.
What sealant do you use?
The product depends on the job: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. Brands we use include Arbo and Everbuild.
Why has my new-build shower seal failed already?
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.
Is there a guarantee?
Yes. Each job is guaranteed for twelve months, large or small.
Should I go to my builder first?
Report it to the builder first while you’re covered. If it isn’t resolved, we can reseal it properly.
Do you take on second-fix sealing for builders?
Yes. Second-fix sealing in bathrooms, kitchens, frames and floors is part of what we do. We clean and prime joints properly to keep callbacks down.
Work for landlords, hotels and businesses
Whether it’s one flat or a portfolio, the work is the same standard: the old material taken out, careful preparation and a 12-month guarantee.
A neglected joint can let water reach the structure, which is a bigger problem in a rented property. Resealing at the right time is simple maintenance.
Common problems we fix in East Hanney
Not every new-build joint gets the right sealant: caulk where water collects, or a rigid product on a moving joint. Neither lasts long.
Most people get in touch when they notice something like this:
- Gaps opening as the house dries out and settles
- Untidy sealant flagged on a snagging list
- Beads laid onto grit and dust from the build
- Plot mastic for developers ahead of handover
Whether the job is in East Hanney itself or nearby, the right material for each joint matters as much as a neat finish.

Should I try it myself first?
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions, and the work is guaranteed for a year.
If you’re set on DIY, put the effort into 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.
The process
The work is kept neat and contained to the area we are working on. The job generally takes a few hours in a single home. Somewhere like East Hanney needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. We bring what the job needs, so it can be finished in one trip where possible.
- We go through the snagging list or plot schedule and agree the joints to do.
- Failed or untidy sealant is cut out completely.
- Surfaces are cleaned of building dust and primed where needed.
- New sealant suited to each joint is applied and tooled neatly.
- We check every joint and tell you how long each needs to cure.

Aftercare tips
How long the joints last depends on use and care. Here’s what we suggest:
- Photograph failed sealant before it’s redone
- Wait for the cure time before using a resealed shower
- Don’t seal over failed sealant yourself
- Act quickly if a seal starts to leak
Leave the sealant for the cure time we give you before showering or bathing. Most silicones need around a day before water reaches them.
If a shower tray or bath seal splits in the first year, look for movement. Getting it resealed properly, and any movement checked, stops it recurring.
How we quote for new build mastic
Jobs vary more than people expect. The main factors:
- Access and height
- How much there is to do
- How many rooms, windows or areas are involved
- The old material and how stubborn it is
Every job is a little different, so we quote each one individually. Size, access and the product the joint needs all play a part.
What we need to know
The more you tell us, the more accurate the quote. When you ask for a quote, tell us:
- Where the property is
- Access, such as stairs, a lift or height
- If someone has resealed it before
- Photos by email, if that’s easy
Asking for a quote is easy: let us know what needs doing and where, and roughly how big it is. Photos by email help us understand the job, and we’ll take it from there.
Why it’s worth doing now in East Hanney
A failed shower or bath seal in a new home lets water into floors and walls that are still drying out. Dealing with it early keeps the damage away from ceilings, floors and finishes. Around East Hanney, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
Homes and businesses are quoted the same way: the amount of work, the access and the products needed. Call for a quick quote and we’ll explain what it covers.
