Leave it or put it right?
A quick bead over the top of the old sealant can look fine at first, but it cannot bond to what’s underneath. Taking it all out and starting again is the only way to get a lasting seal. In a small place like Sandleford, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
Some things make a job bigger or smaller: the old material and how easily it comes out, whether mould needs treating, and whether the work is at height. Your quote takes all of that into account.

Sandleford: your questions answered
Do you cover Sandleford for new build mastic?
Yes, Sandleford is within the area we cover. We work across London and the South East. You can phone 0345 464 0079 or send us an email and tell us what needs doing.
I let a flat near Newbury station. Can you help?
Yes. We work for landlords and letting agents as well as homeowners. Just phone 0345 464 0079 or send us an email with the address and what needs doing, and we’ll send you a clear quote.
Do the sealants smell?
There can be a smell while the sealant cures. Opening a window helps.
Why does sealant fail so quickly in new builds?
Lots of new homes see sealant crack early, because the house is drying and settling. Rushed application on dusty surfaces makes it worse.
Can you match the sealant colour to my new kitchen or bathroom?
White and clear are the most common, but sealant comes in other colours too. We choose one to suit the room before we begin.
What should I tell you?
Just the basics: where it is, what you’ve noticed and how we reach it. After that, simply call 0345 464 0079 or send us an email.
How long should I leave it?
Many sealants skin over quickly but take longer to cure fully. We’ll tell you how long to leave the joint before we leave.
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, but cosmetic gaps can wait for movement to slow.
What affects the cost of new build mastic
The quote reflects the job in front of us. We take into account:
- Any working-time requirements on site
- Which sealant suits the joint
- Access and height
- The old material and how stubborn it is
Every job is a little different, so each one gets its own quote. Size, access and the product the joint needs all play a part, and we’ll explain the quote if you ask.
Asking for a quote
The more you tell us, the more accurate the quote. When you get in contact, it helps to mention:
- What the problem is, such as mould, gaps, leaks or cracking
- Where the property is
- Any access issues, like height or stairs
- Photos by email, if that’s easy
Quotes start with a quick conversation. Describe the problem, the location and the size of the job. Whenever you’re ready, call 0345 464 0079 or email us.
How to look after the new joints
Joint life depends on how it’s used and looked after. Here’s what we suggest:
- Resist patching a failed seal with a tube from the DIY shop
- Wipe joints with warm soapy water
- Watch for new gaps as the house dries out
- Open a window or run the fan after bathing
Follow the cure time we give you before the area gets wet. Silicone is generally left for about a day to cure enough for use.
Leave a failed new-build seal and water can reach the floor and the ceiling below. Early resealing keeps the job small and the new finishes intact.
Different surfaces, different methods
Bathrooms and en suites
Shower trays in new homes often move slightly in the first year. The joint is stripped back before the new bead goes in with baths filled first.
Skirting and floors
Where the floor meets a bath panel or kitchen plinth, the joint keeps mop water out. They get a flexible, water-resistant sealant.
What happens on the day
Most of a good job is in the preparation, and we don’t rush it. Every joint is cleaned and dried before new material goes in. All told, the work takes a few hours in a single home. In a small place like Sandleford, access is usually the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- We start by going through the snagging items or plot schedule with you.
- The failed sealant is removed completely down to clean surfaces.
- 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.
Before we arrive
- Try not to wet indoor joints just before the visit
- Clear items away from the joints we are working on
- Mention any parking rules near the property

Advice
Common problems we fix in Sandleford
Once people move in, baths and trays take weight and bed down. If a bath wasn’t filled when it was sealed, the bead is stretched the first time it’s used and can tear.
People normally contact us when they notice something like this:
- Sealant applied over dusty or wet surfaces
- Cracked caulk along new skirting
- Cracks appearing as a new home settles
- Second-fix sealing on new plots
Around Sandleford, as everywhere, new build mastic is only as good as the preparation behind it.
