How we handle new build mastic in Burwash
A new build should have a neat, sound bead at every joint. When the finish is smeared, patchy or already cracking, it’s worth putting right early, before water gets into the floor or walls. Typical jobs include cracked sealant around new window and door frames and messy sealant that spoils new finishes, across skirting & floors, plot handovers and bathrooms & en suites.
Around Burwash, older homes often have timber floors that move through the year, so skirting and threshold joints need a flexible sealant rather than a rigid filler.
We guarantee the work for a year. If there’s a problem with our work within the year, let us know and we will sort it.

How long does the job take?

Do you remove the old sealant?
Yes, every time. New sealant won’t bond properly to old, so the joint is cleaned back first.

The process
At the end, we look at the finished work together and explain the cure time. The work normally takes a few hours in a single home, depending on the size of the job. In a small place like Burwash, access is generally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We go through the snagging list or plot schedule and agree the joints to do.
- The old bead comes out in full, with no layer left behind.
- Surfaces are cleaned of building dust and primed where needed.
- We apply a sealant that suits each joint and tool it to a neat finish.
- We check every joint and tell you how long each needs to cure.
Before we arrive
- Tell us about access, such as stairs, a lift or high-level joints
- Where the joints are inside, avoid wetting them before we arrive
- Plan for the work area to be out of bounds to pets and children

Advice
What affects the cost of new build mastic
The price is agreed before any work begins. It’s based on:

There are no prices on our website, because each job is priced on what it involves. For a quick quote, please call 0345 464 0079 or send us an email and we will talk you through it.

Why deal with it now?
DIY kits do not solve the main problems with new-build sealant: grit, unprimed surfaces and old layers underneath. Cutting out, cleaning and priming are what make the difference. In a small place like Burwash, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
A few things move the cost up or down: how much old sealant there is and how stubborn it is, any mould to treat, and whether the work is at height. We take all of that into account in your quote.

When something else is needed
New sealant cannot fix everything, and we’d rather say so up front. Sealant won’t put right:
- Structural cracks in walls or ceilings
- A tray or bath that is not properly supported, until it’s fixed
- Damaged fittings that need replacing
If you’re not sure, just ring 0345 464 0079 or drop us an email and we’ll give you a straight answer.

When to call us in Burwash
Sealant applied onto damp surfaces does not bond well. On a busy site, joints aren’t always given time to dry.
Most people get in touch after spotting something like this:
- Messy sealant that spoils new finishes
- Second-fix sealing on new plots
- Sealant that never bonded to the surface
- Gaps opening as the house dries out and settles
In and around Burwash, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.
Before you book anyone
- Is VAT in the price?
- Who turns up on the day
- What preparation is included
- Whether all the old sealant comes out first
Should I try it myself first?
Sealing over old silicone is the commonest DIY error. Silicone does not stick to old silicone, so it lifts and traps water and mould underneath. Everything old must be removed first.
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 does not work out, we can still put it right.
Surface by surface
Skirting and floors
As timber and screed dry, skirting and floors shift. We use a flexible product rather than caulk painted or coloured to suit.
Bathrooms and en suites
Baths, showers, basins and trays in new bathrooms are the most common new-build reseal. The old sealant comes out and anti-fungal sanitary silicone goes in after cleaning and priming.
