New build mastic for homes and businesses in Wickham
We work in new homes and on new-build sites across Wickham. One shower or a whole phase of plots, the method doesn’t change: remove, clean, prime where needed, then a neat new bead. We work on skirting & floors, show homes and bathrooms & en suites, and the jobs we see most are worktop and upstand sealant coming away and plot mastic for developers ahead of handover.
Somewhere as small as Wickham, new homes tend to be conversions, self-builds or a few houses rather than an estate. Each still needs its sealant and floor joints finished properly.
Each job carries a 12-month guarantee, large or small.

How it works
The work is kept neat and contained to the joints we’re treating, so you can get on with your day. Expect the work to take a few hours for most snagging lists, longer for a run of plots. Somewhere like Wickham 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.
- We start by agreeing which joints are on the list, from the snagging sheet or plot schedule.
- We cut out every bit of the failed or messy sealant.
- Each joint is cleaned of dust and grit, then primed if required.
- A sealant chosen for each area goes in and is tooled smooth.
- Finally, each room is checked and you are given the cure time.
Before we arrive
- Mention any parking rules near the property
- Plan for the work area to be out of bounds to pets and children
- Mention any leaks or damp you’ve noticed

Aftercare tips
After the cure time, these simple habits help:
- Wait for the cure time before using a resealed shower
- Report sealant problems to your builder during the snagging period
- Record problems with dated pictures
- Avoid running a DIY bead over the old one
Avoid standing on the rim of the bath or the edge 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.
What affects the cost of new build mastic
Some jobs are bigger than they look, and some smaller. The main factors:
- Access and height
- The number and length of the joints
- How many rooms, windows or areas are involved
- The product the joint needs
Leaving a failed joint usually makes the job bigger, not smaller, as water and mould keep getting in. If you’re unsure, phone 0345 464 0079 or send us an email for an honest opinion and a quote.
Asking for a quote
Photos help, but a description is a good start. Please mention:
- How we’d reach the joints
- The type of property
- The address or postcode of the job
- If someone has resealed it before
For a quick quote, get us on the phone, or email us if that’s easier. Tell us about the joints that need doing and we’ll talk you through the work.
Do you need new build mastic in Wickham?
Not every new-build joint gets the right sealant: decorators’ caulk in a wet area, or a stiff sealant where there’s movement. Both fail early.
The problems people normally mention when they call include:
- Second-fix sealing on new plots
- Cracks appearing as a new home settles
- Smeared, uneven beads picked up at snagging
- Gaps behind new kitchen upstands
For new homes near Kintbury station, it’s worth checking the sealant early, while snags are still fresh.

Work for landlords, hotels and businesses
Letting agents often deal with us directly. Send the address, what’s needed and the access arrangements.
A neglected joint can let water reach the structure, which is a bigger problem in a rented property. Keeping joints in good order is simple maintenance that we can handle for you.

FAQs for Wickham
Is Wickham within the area you cover?
Yes, we do. 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.
Do you work for landlords with property near Kintbury station?
Yes, rental work is part of what we do. You can ring 0345 464 0079 or send us an email with the address and a few details, and we’ll give you a fixed price before work begins.
Will the old sealant be removed?
Yes. We cut out all the old sealant and clean the joint before applying anything new.
Should I try DIY first?
For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. Most DIY failures come from sealing over old material, wet joints or too much sealant.
Should I go to my builder first?
If you’re still within the builder’s snagging or warranty period, report it to them first. If they’re slow or the fix doesn’t last, we can help.
Will it make a mess?
Very little: the area around the joints is protected first, and we clear up the old sealant and our materials before we leave.
Where are you based?
Mr Mastic is based in Crawley. We cover Wickham and the rest of West Berkshire, along with the rest of our area.
What do you put in the joint?
Quality sealants from brands including Arbo and Everbuild, picked for each joint. We’ll tell you what we’re using and why.
What sealant work can’t fix
In fairness, some problems need a different trade:
- Your warranty claim itself, which is between you and the builder
- Baths and trays that move too much for sealant to cope with
- Plumbing faults behind the sealant
If in doubt, ring 0345 464 0079 or send us an email and we’ll say what we think before booking.
Surfaces we seal
- Skirting & floors
- Show homes
- Bathrooms & en suites
- Windows & doors
- Plot handovers
- Kitchens
Should I try it myself first?
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
Joints and finishes in Wickham homes
London and the South East are among the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
