About our new build mastic in West Byfleet
Dust is the enemy of new-build sealant. Each joint is cleaned of dust and primed where the product calls for it, so the sealant actually sticks instead of bonding to the dust. We work on skirting & floors, plot handovers and windows & doors, and people most often call us about messy sealant that spoils new finishes and cracked caulk along new skirting.
In smaller places like West Byfleet, new homes tend to come as small developments or single plots. The sealant around baths, showers, frames and skirtings needs to be right from the start.
A one-year guarantee comes as standard, so you’re not left on your own once the job is done.

Surface by surface
Skirting and floors
Floors and skirting move as the house dries and the heating runs. We use a flexible product rather than caulk in a colour to suit.
Plot handovers
Developers can send the plot schedule and specification for a quote. We seal bathrooms, kitchens, frames and floors as agreed.
What we’re called out for in West Byfleet
Fresh sealant can be knocked or cut by trades finishing off. A bead disturbed before it has cured may never seal properly and it shows once the home is in use.
If you can see any of these, it’s time to have the joints looked at:
- Joints pulling apart as timber shrinks
- Skirting joints opening in the first winter
- Sealant work across a run of new homes
- Cracked sealant around new window and door frames
Around West Byfleet, as everywhere, new build mastic is only as good as the preparation behind it.
Questions to ask before booking
- Who does the work, and how experienced they are
- What the quote includes, VAT included or not
- When the joint can take water or movement
- How the colour is chosen
The process
We keep the work tidy and contained to the area we’re working on. The job usually takes anything from a few hours to several days, depending on the number of plots, and we tell you how long to leave it before we go. A visit to West Byfleet is planned like any other: the time, the access and where to park are agreed in advance. If the work is outside, the weather plays a part, as sealant needs a dry surface.
- Each joint is checked for movement before we start.
- Old sealant is cut out and the joints cleaned.
- We make sure the joints are dry and prime them if needed.
- New sealant goes in, with baths filled first so they’re at their heaviest.
- The finished joints are checked and the cure times given.
Getting ready for the visit
- Mention if the joints have been sealed before
- Move anything stored near the joints
- Let us know about stairs, lifts or work at height

West Byfleet: your questions answered
Can you do new build mastic in West Byfleet?
Yes. Our work covers London and the South East, and West Byfleet is part of that. Just phone 0345 464 0079 or send us an email with a few details of the job, and we’ll send you a clear quote.
Will you come out to West Byfleet?
Yes, West Byfleet is covered. Our work covers London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.
How long will you be here?
That depends on how much there is to do, but most jobs take a few hours for most snagging lists, longer for a run of plots. We’ll give you a better idea when we quote.
Do you hold any approvals?
Yes. Mr Mastic is an ARBOMaster approved applicator and we are fully insured too.
Where do you work from?
We’re based in Crawley, West Sussex, and we work across South East England, London and Scotland.
Is there any odour?
It depends on the product. Some products have a noticeable smell, others very little.
Do I have to be there?
That depends on where the joints are. For work indoors, someone needs to let us in, while outside work can sometimes be arranged differently.
Can you work on commercial sites?
Yes. Hotels, offices and other businesses use us, and we are fully insured.
Can I do it myself?
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and doesn’t move well, and getting the depth right matters as much as the look.
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.
What affects the cost of new build mastic
We do not publish a price list, because no two jobs are the same. The quote depends on:
- How many areas need sealing
- The number and length of the joints
- Working hours on commercial sites
- Access and height
We don’t show prices on the website, because each job is priced on what it involves. For a quick quote, please phone 0345 464 0079 or send us an email.
Asking for a quote
Photos by email are helpful but not essential. Please mention:
- The type of property
- The rough size of the job
- Photos by email, if that is easy
- What the problem is, such as mould, gaps, leaks or cracking
For a quote, ring 0345 464 0079 or drop us an email with the location and a short description of the problem. You will have a clear quote before work begins.
Why deal with it now?
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. Homes in smaller places like West Byfleet can face more weather, and failed outside joints let damp into walls. Indoors, a failed seal lets water into floors and panels as it would anywhere.
Rather than a set price list, we price the job in front of us: the amount of work, the old material and the access. The price is agreed before we begin.
Why us?
- Full insurance on every job
- ARBOMaster approved applicator
- Colour picked to suit the job
- Every job guaranteed for a year
