What we are called out for in Droxford
A new house holds a lot of water from the build, and it dries out over the first couple of years. Drying timber shrinks and pulls joints apart.
The most common problems we see are:
- Joints pulling apart as timber shrinks
- Untidy sealant flagged on a snagging list
- Second-fix sealing on new plots
- Gaps behind new kitchen upstands
In and around Droxford, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.

The process
All our tools and materials come with us in the van, so there’s nothing for you to buy. Once we have agreed what’s being done, the area is protected and the work begins. It normally takes a few hours for most snagging lists, longer for a run of plots. Somewhere like Droxford needs a little journey planning: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.
- First, the list of joints is agreed from your snagging sheet or plot schedule.
- Every bit of the old builder’s sealant is cut out, with no layer left behind.
- Joints are vacuumed and cleaned of building dust.
- 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.
Before we arrive
- Where the joints are inside, avoid wetting them before we arrive
- Plan for the work area to be out of bounds to pets and children
- On commercial sites, let us know about site rules

FAQs for Droxford
Is Droxford in your area for new build mastic?
Yes, Droxford is within the area we cover. We work across London and the South East. You can phone 0345 464 0079 or email us and tell us what needs doing, and we’ll give you a clear price.
Is there a guarantee on new build mastic in Droxford?
Every job comes with our one-year guarantee, wherever it is. We are fully insured, and an ARBOMaster approved applicator.
What does new build mastic cost?
Every job is different, so each one gets its own quote. To get one, call 0345 464 0079 or send us an email and let us know what needs doing and where.
Will the old sealant be removed?
Yes, every time. New silicone doesn’t stick to old silicone, so any old material comes out before anything new goes in.
What should I tell you?
Tell us what needs doing and where. If we need more, we will ask.
Can landlords and businesses book you?
Yes. As well as householders, we work for landlords, agents, businesses and hotels across Hampshire.
Can tenants book the work?
Of course. Check with your landlord; we can send the quote to them too.
Is it worth resealing while the house is still settling?
Where water is getting through, don’t wait. Hairline cosmetic gaps can wait until the house has settled.
What affects the cost of new build mastic
Jobs vary more than people expect. The main factors:
- The product the joint needs
- Whether the work is at height
- The amount of work
- How many rooms, windows or areas are involved
Instead of a standard rate, we price the job in front of us: how many joints, what’s in them now and how we reach them. You will know the price before we begin.
What we need to know
The more you tell us, the more accurate the quote. When you get in contact, it helps to mention:
- Whether it’s a home or a business
- What’s wrong with the joints now
- Where the property is
- If someone has resealed it before
Asking for a quote is easy: let us know what needs doing and where. Photos by email help us understand the job.
Aftercare tips
Joint life depends on how it’s used and looked after. Here’s what we suggest:
- Watch for new gaps as the house dries out
- Raise failed sealant with the developer while you are covered
- Avoid scourers and strong chemicals on sealant
- Photograph failed sealant before it’s redone
Leave the sealant for the cure time we give you before showering or bathing. Most silicones need around a day.
Do not let the snagging period run out with sealant problems unreported. After that, putting it right may fall to you.
When it isn’t the sealant
In fairness, some problems need a different trade:
- Cracked trays, tiles or worktops
- Baths and trays that move too much for sealant to cope with
- Leaks from pipes, valves or wastes, which need a plumber
Not sure which it is? You can call 0345 464 0079 or drop us an email and we will tell you honestly before you book.

Why deal with it now?
The builder is usually the first port of call while the snagging or warranty period runs. If it’s slow, or the same joint keeps failing, a proper reseal from a specialist is the next step. Around Droxford, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
There are no prices on our website, because each job is priced on what it involves. For a quick quote, please phone 0345 464 0079 or send us an email and we’ll talk you through it.

DIY sealant or a professional job?
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
Sealing over old silicone is the commonest DIY error. New silicone will not bond to old, so it peels away and traps moisture behind it. All the old material has to come out first.
