Questions from Heckfield
Do you cover smaller places like Heckfield?
Yes. Heckfield is within the area we cover, which takes in towns, villages and rural addresses. Our work covers London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
I let a flat near Mortimer station. Can you help?
Yes. We work for landlords and agents as well as householders, and several properties can be quoted together. Just phone 0345 464 0079 or email us with the address and what needs doing, and we will give you a clear quote.
Are you fully insured?
Yes. Mr Mastic is fully insured, with over 20 years’ experience in sealant work.
Is there any odour?
Some sealants have a smell while they cure, but it fades. Opening a window helps.
Do you take on second-fix sealing for builders?
Yes. We carry out plot mastic and second-fix sealing for builders and developers. Send the schedule and any specification and we’ll give you a quote.
Can I do it myself?
You can, for simple jobs. Preparation is everything: all the old sealant out, and a clean, dry joint. If it doesn’t work out, we can redo it.
Do I need to be at home?
We need access to the joints, so we will agree that with you when we book. Indoors, that normally means someone at home.
How much does new build mastic cost in Heckfield?
The cost depends on the size of the job, access and how much old sealant has to come out. Call for a quick quote.
Can I do it myself?
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and does not move well, and getting the depth right matters as much as the look.
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.
Why it’s worth doing now in Heckfield
Running a new bead over the builder’s sealant might look tidy for a few weeks, but it will not bond to the old layer. A lasting seal starts with removing the old one completely. Around Heckfield, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
Every job is a little different, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all make a difference, and we’ll explain the quote if you ask.
Why book with us
- Old sealant always removed completely
- Full insurance on every job

What sealant work cannot fix
We’d rather tell you now than do work that will not last, so these are the limits:
- Cracked trays, tiles or worktops
- Baths and trays that move too much for sealant to cope with
- Deciding who is responsible under a builder’s warranty
If you are not sure, just ring 0345 464 0079 or email us and we will give you a straight answer before you book.

What the job involves on each surface
Skirting and floors
Wet-area floor joints need a flexible seal. They get a flexible, water-resistant sealant.
Bathrooms and en suites
Baths, showers, basins and trays in new bathrooms are the most common new-build reseal. We cut out the failed bead, clean and prime, and reseal with anti-fungal sanitary silicone.
Looking after it afterwards
Aftercare is simple:
- Record problems with dated pictures
- Raise failed sealant with the developer while you are covered
- Avoid scourers and strong chemicals on sealant
- Look at the sealant regularly in the first couple of years
Follow the cure time we give you before the area gets wet. Most silicones need around a day before water reaches them.
Lifting sealant traps moisture and mould behind it. Resealing before mould gets in keeps the job straightforward.
What we do, step by step
There isn’t much for you to do on the day. Show us the job and we will take it from there. The work itself takes anything from a few hours to several days, depending on the number of plots from start to finish. Somewhere like Heckfield 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.
- Each joint is checked for movement before we start.
- We remove the failed sealant and clean the joints.
- We make sure the joints are dry and prime them if needed.
- Baths are filled with water, then the new sealant is applied.
- We check every joint and leave you with the cure times.
