What happens if it’s left?
A hairline gap at a skirting can wait, but a leaking seal can’t. Not sure whether yours can wait? You can call 0345 464 0079 or email us with a few photos. In a small place like Egham Wick, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.

What we can’t put right
New sealant cannot fix everything, and we’d rather say so up front. Sealant won’t put right:
- Settlement cracks that need a surveyor
- A tray or bath that is not properly supported, until it’s fixed
- Deciding who is responsible under a builder’s warranty
If in doubt, ring 0345 464 0079 or send us an email and we’ll say what we think before booking.
What we seal
- Show homes
- Plot handovers

- Kitchens
Do you need new build mastic in Egham Wick?
New homes are full of moisture from plaster, screed and concrete, which takes a year or two to dry out. Drying timber shrinks and pulls joints apart.
The problems people normally mention when they call are:
- Gaps opening as the house dries out and settles
- Skirting joints opening in the first winter
- Beads laid onto grit and dust from the build
- Untidy sealant flagged on a snagging list
For new homes near Virginia Water station, it’s worth checking the sealant early, while snags are still fresh.
Questions to ask before booking
- What product goes in the joint
- Whether VAT is included
- Are they insured?
- How long to leave it before use
Work for landlords, hotels and businesses
Mouldy or split sealant often shows up at the end of a tenancy, and it’s easy to sort out between tenants. Several properties can go on one quote.
We work for letting agents and landlords as well as householders. Sealant work between tenants keeps a property looking cared for.
How it works
We work through the job in order: protect, prepare, seal, tidy. Typically it takes anything from a few hours to several days, depending on the number of plots. Somewhere like Egham Wick needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. We bring what the job needs, so it can be finished in one trip where possible.
- We start by going through the snagging items or plot schedule with you.
- The failed sealant is removed completely down to clean surfaces.
- 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.
Preparing for the visit
- Try not to wet indoor joints just before the visit
- Tell us about any water getting in
- Mention any sign-in or site rules at work premises

DIY sealant or a professional job?
If you’re set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it doesn’t work out, we can still put it right.
The biggest DIY mistake is sealing over old sealant. Silicone doesn’t stick to old silicone, so it peels away and traps moisture behind it. All the old material has to come out first.
What affects the cost of new build mastic
We don’t publish a price list. The quote depends on:
- Whether the work is at height
- The old material and how stubborn it is
- The size of the job
- The number of rooms or windows
A few things move the cost up or down: the old material and how easily it comes out, any mould to treat, and whether we need extra access for height. Your quote takes all of that into account.
Helping us quote
When you contact us, these details help:
- The problem you’ve noticed
- Where the property is
- The type of property
- Any previous sealing or DIY work
Every job is quoted individually. Simply phone 0345 464 0079 or send us an email and describe the job, and pictures are welcome.

Egham Wick questions
I let a flat near Virginia Water station. Can you help?
Yes. We work for landlords and agents as well as homeowners, and several properties can be quoted together. Just call 0345 464 0079 or send us an email with the address and what needs doing, and we’ll give you a clear price.

Is the work guaranteed?
Yes. There’s a 12-month guarantee on every job, large or small.
Are you fully insured?
Yes. Mr Mastic is fully insured.
Will you leave a mess?
No. We protect the surfaces around the joints, and we clear up the old sealant and our materials before we leave.
Is it worth resealing while the house is still settling?
It depends on whether water is getting through. A leaking shower or bath seal should be redone right away, while small cosmetic gaps can wait a while.
Which products do you use?
We choose the sealant for the joint, not the other way round. Movement, water and weather all affect the choice, and we’ll tell you what we’re using.
Can you reseal over the builder’s sealant?
No. Fresh silicone doesn’t stick to the old layer, so sealing over the top fails quickly. The old sealant always comes out first.
