Hatherden New Build Mastic
New build mastic across Hatherden and nearby, with old sealant always removed completely and a 12-month guarantee.
- Sealant that never bonded to the surface

Work for landlords, hotels and businesses
We work for letting agents and landlords as well as householders. Resealing between tenancies keeps a property looking cared for before the next move-in.
We also work for property managers and facilities teams. Several sites can go on one quote, and we are fully insured.
New build mastic in Hatherden, done properly
We never seal over a failed new-build bead. Fresh silicone cannot bond to the old layer, so it all comes out before we clean, dry and reseal. We work on windows & doors, kitchens and skirting & floors, and the jobs we see most are second-fix sealing on new plots and gaps between new skirting and floors.
Work in a small place like Hatherden just needs the journey and access planning, and the work itself is the same as on any site.
All our work is covered by our 12-month guarantee, wherever you are in Hampshire.

New build mastic in Hatherden: local notes
The South East is one of the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
For new homes near Andover station, it’s worth checking the sealant early, while snags are still fresh. Around Hatherden, as everywhere, new build mastic is only as good as the preparation behind it.

How we quote for new build mastic
The price is agreed before any work begins. It’s based on:
- How many areas need sealing
- How much old sealant there is and how hard it is to remove
- Whether there’s mould to deal with
- Access and height
Instead of a standard rate, we look at what your job involves: the amount of work, the old material and the access. You will know the price before we begin.
Helping us quote
Photos help, but a description is a good start. Try to tell us:
- Where the property is
- If it’s domestic, commercial or a hotel
- Pictures of the joints, sent by email
- Roughly how big the job is
For a quote, call 0345 464 0079 or drop us an email with the location and a short description of the problem. We will send you a clear quote before any work starts.
Should I try it myself first?
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions, and the work is guaranteed for a year.
The biggest DIY mistake is sealing over old sealant. Silicone does not stick to old silicone, so it lifts and traps water and mould underneath. All the old material has to come out first.
Why it’s worth doing now in Hatherden
Small cosmetic gaps can wait for the house to settle, but water getting through can’t. Not sure whether yours can wait? You can phone 0345 464 0079 or email us with a few photos and we will tell you. Around Hatherden, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
The cost reflects the work involved, not a rough estimate. That’s why we ask a few questions first and agree the price before starting.

Aftercare tips
After the cure time, these simple habits help:
- Raise failed sealant with the developer while you’re covered
- Get a leaking seal dealt with straight away
- Do not seal over failed sealant yourself
- Check bath and shower seals every few months as the house settles
Wipe the sealant with warm soapy water. Keep scourers and harsh chemicals off it as they wear the bead.
The sooner you deal with untidy or cracking sealant, the less there is to put right. Small faults turn into leaks if left.
Hatherden questions
Do you work for landlords with property near Andover station?
Yes, landlords and agents are among the people we work for, and several properties can go on one quote. Just ring 0345 464 0079 or send us an email with the address and what needs doing, and we will give you a clear price.
Do you cover Hatherden for new build mastic?
Yes, Hatherden is within the area we cover. We work across London and the South East. Just phone 0345 464 0079 or email us with a few details of the job.
Do you remove the old sealant?
Yes, every time. New sealant will not bond properly to old, so the joint is cleaned back first.
What do you put in the joint?
We choose the sealant for the joint, not the other way round. Movement, water and weather all affect the choice, and we will tell you what we are using.
Is the work guaranteed?
Yes. All our work carries a 12-month guarantee.
Who should fix failed sealant in a new build?
If you’re still within the builder’s snagging or warranty period, report it to them first. If it isn’t sorted, or keeps failing, get in touch with us.
Can you reseal over the builder’s sealant?
No. The old sealant is cut out fully, the joint cleaned and primed where needed, and a new bead applied.
Is it worth trying it myself?
For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. The usual mistakes are sealing over old sealant, sealing a damp joint and using too much.
What sealant work cannot fix
Before you book, it’s worth knowing the limits too:
- Movement caused by a poorly fitted tray or bath
- Deciding who is responsible under a builder’s warranty
- Settlement cracks that need a surveyor
If you’re not sure, just phone 0345 464 0079 or email us and we will give you a straight answer before you book.
