Work for landlords, hotels and businesses
If you manage several properties in or around Lyne, several properties can be quoted together. Send us the addresses and the work at each, and pictures by email help.
We also work for businesses, from offices to washrooms and kitchens. For commercial premises, we can talk through working times when we quote.
How we handle new build mastic in Lyne
Some new-home owners let the house settle before resealing. For small cosmetic gaps, that’s reasonable, but a seal that is letting water through needs doing now. If you have smeared, uneven beads picked up at snagging and plot mastic for developers ahead of handover, we can put it right, on skirting & floors, show homes and bathrooms & en suites alike.
Work in a small place like Lyne just needs the journey and access planning, and the work itself is the same as on any site.
Whatever the size of the job, it’s backed by our one-year guarantee.

The process
Once we’re on site, we compare the joints with what we discussed. If we find something unexpected, we talk it through with you first. Most jobs then take anything from a few hours to several days, depending on the number of plots. Somewhere like Lyne needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.
- We start by going through the snagging items or plot schedule with you.
- The failed sealant is removed completely.
- We clean out the dust and grit left from the build.
- Primer goes on where the surface and product need it, then the new sealant.
- We tool every joint neatly and tell you when each area can be used.
How to prepare
- Let us know about earlier repairs to the joints
- Clear the area around the work
- Where the joints are inside, avoid wetting them before we arrive
Getting a quote
Getting a quote is simple: let us know the job and the location. A few photos by email make the job easier to understand, and we will take it from there.
Related advice
DIY sealant or a professional job?
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and does not move well, and the joint depth matters as much as the finish.
What affects the cost of new build mastic
Every job gets its own quote. These are the things that affect it:
- Working hours on commercial sites
- Whether old sealant or filler has to be cut out
- The number and length of the joints
- How many areas need sealing
The cost reflects the work involved, not guesswork. That is why we ask about the job first and agree the price before starting.
What to tell us for a quote
What to tell us when you ask for a quote:
- How we’d reach the joints
- If someone has resealed it before
- The address or postcode of the job
- What the problem is, such as mould, gaps, leaks or cracking
A good description makes for an accurate quote. Tell us where the job is, what’s wrong and how much there is.

Questions from Lyne
Can you do new build mastic in Lyne?
Yes. We work across London and the South East, and Lyne is part of that. Just call 0345 464 0079 or drop us an email with a few details of the job.
Do you cover smaller places like Lyne?

Do you work for hotels and businesses?
Yes. Larger jobs can be planned room by room or area by area.
How long does new build mastic take?

Are you ARBOMaster approved?
Yes. Mr Mastic is an ARBOMaster approved applicator.
Will there be a smell?
Sometimes, a little. Any smell clears as the sealant cures.
Which products do you use?
The product depends on the job: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. We use products from Arbo and Everbuild.
Do I have to be there?
It depends on the job. For work indoors, someone needs to let us in.
When something else is needed
In fairness, there are a few things sealant won’t fix:
- Baths and trays that move too much for sealant to cope with
- Structural cracks in walls or ceilings
- Deciding who is responsible under a builder’s warranty
If you are not sure, just ring 0345 464 0079 or email us and we’ll give you a straight answer.

What new build mastic looks like in Lyne
Rainfall in the South East is lower than in much of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
For new homes near Chertsey station, it’s worth checking the sealant early, while snags are still fresh.
Lyne is about 3 miles south of Egham, in Surrey. Across the KT16 area, we cover new build mastic for homes and businesses. Our Surrey coverage runs to 395 places, Lyne among them. Our Reading page covers work nearby.
Work in KT16 is quoted and booked the same way as anywhere else. If you need new build mastic at a property on Almners Road, Pantiles Close and Lyne Lane or a nearby road, we can help. Neighbouring places we cover for new build mastic include Chertsey (1 mile east), Trumps Green (2 miles west), Ottershaw (2 miles south), Stonehill (2 miles south-west) and Row Town (2 miles south-east).

Local landmarks in Lyne

Keeping the joints in good condition
Good habits help new joints last longer. Our tips:
- Follow the cure time we give you
- Use the extractor fan every time you shower
- Resist patching a failed seal with a tube from the DIY shop
- Don’t wait for the house to settle if water is getting through
Avoid standing on the rim of the bath or the edge of the tray in the first few weeks. Report any movement in a bath or tray.
Do not let the snagging period run out with sealant problems unreported. After that, putting it right may fall to you.
What we are called out for in Lyne
Baths and trays settle under load once the home is lived in. If a bath wasn’t filled when it was sealed, the bead is stretched the first time it’s used and the sealant may split.
The problems people generally mention when they call include:
- New-build shower sealant that has already split
- Sealant applied over dusty or wet surfaces
- Untidy sealant flagged on a snagging list
- Sealant work across a run of new homes
In and around Lyne, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.
