About our new build mastic in Great Canfield
For builders and developers, we work through plots to the schedule you give us. We seal bathrooms, kitchens, windows, doors and skirting so plots are ready to hand over using the right product for each joint. We work on skirting & floors, plot handovers and bathrooms & en suites, and the jobs we see most are second-fix sealing on new plots and worktop and upstand sealant coming away.
Older homes in small places like Great Canfield often have timber floors that move with the seasons, which is why skirting and threshold joints need a flexible sealant, not filler.
Each job carries a 12-month guarantee, large or small.

Common problems we fix in Great Canfield
Sealant is often one of the last jobs before handover. Dusty, unprimed joints are common, so the bead never bonds properly.
Most people get in touch when they notice one of these:
- Cracked caulk along new skirting
- Smeared, uneven beads picked up at snagging
- Sealant applied over dusty or wet surfaces
- New-build shower sealant that has already split
If you’ve bought a new home near Stansted Airport station, the sealant around baths, showers and frames is worth checking in the first year or two.

Common questions in Great Canfield
Do you work for landlords with property near Stansted Airport station?
Yes, we work for landlords and agents. You can call 0345 464 0079 or drop us an email with the address and a few details, and we’ll give you a fixed price before work begins.
Is Great Canfield within the area you cover?
Yes, smaller places are covered as well as towns. Our work covers London and the South East. Just mention lanes, gates or anything else about the route when you book.
Is there any odour?
That depends on the sealant. Some products have a noticeable smell, others very little, and any smell fades as they cure.
Do you do commercial work?
Yes, regularly. Larger jobs can be planned room by room or area by area to suit the site.
Where is Mr Mastic based?
We are based in Crawley, West Sussex, and we work across South East England, London and Scotland.
Do you remove the old sealant?
Yes, every time. New sealant will not bond properly to old, so the joint is cleaned back first.
Can you do plot mastic on a new development?
Yes. We take on second-fix sealant work across new plots. We clean and prime joints properly to keep callbacks down.
What information do you need?
The location, the problem and the rough size of the job. Photos by email help too.
Work for landlords, hotels and businesses
We also work for businesses, from offices to washrooms and kitchens. On commercial sites, working times can be discussed when we quote.
A neglected joint can let water reach the structure, which matters even more when someone else lives there. Resealing at the right time is simple maintenance.
How the visit works
We keep the work tidy and contained to the joints we are 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, and we explain the cure time before we leave. In a small place like Great Canfield, access is generally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We look at why each joint failed, including any movement.
- Old sealant is cut out and the joints cleaned.
- Joints are dried and primed where the product calls for it.
- Baths are filled with water, then the new sealant is applied.
- We check every joint and leave you with the cure times.
Preparing for the visit
- Tell us about any water getting in
- On commercial sites, let us know about site rules
- Let us know about stairs, lifts or work at height

What we cannot put right
We won’t take on work that will not last, so here’s what sealant cannot put right:
- Broken tiles or a split tray
- Cracking that points to a structural problem
- Movement caused by a poorly fitted tray or bath
If you’re not sure, just ring 0345 464 0079 or send us an email and we will give you a straight answer before booking.
Surfaces we seal
- Kitchens
- Bathrooms & en suites
- Show homes
- Windows & doors
- Plot handovers
- Skirting & floors
Should I try it myself first?
If you are set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it does not work out, we can still put it right.
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, then guaranteed for a year.
