Can I do it myself?
Sealing over old silicone is the commonest DIY error. New silicone won’t bond to old, so it peels away and traps moisture behind it. Everything old must be removed first.
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
About our new build mastic in Hawkley
We never seal over a failed new-build bead. New silicone will not bond to old silicone, so the joint is cut out, cleaned, dried and resealed. If you are dealing with joints pulling apart as timber shrinks and plot mastic for developers ahead of handover, we can help, whatever the surface.
In a village or hamlet like Hawkley, new homes are more likely to be a barn conversion or a handful of houses than a big estate. Each still needs its sealant and floor joints finished properly.
Big or small, you get the same one-year guarantee in Hawkley and across Hampshire.

The process
The work is kept neat and contained to the area we’re working on. Expect the work to take a few hours for most snagging lists, longer for a run of plots, and we explain the cure time before we leave. Somewhere like Hawkley 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.
- 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 down to clean surfaces.
- We clean out the dust and grit left from the build.
- We prime where needed and apply a sealant suited to each joint.
- Each bead is tooled and the cure times explained.
Getting ready for the visit
- Let us know about earlier repairs to the joints
- Plan for the work area to be out of bounds to pets and children
- Mention any tricky access

What the job involves on each surface
Windows and doors
A draught at a new window can be a missed or failed joint. We look at the joints and reseal where needed.
Skirting and floors
As timber and screed dry, skirting and floors shift. We use a flexible product rather than caulk painted or coloured to suit.
Hawkley: your questions answered
Can you help a landlord with a rental near Liss station?
Yes, we work for landlords and letting agents. Just ring 0345 464 0079 or drop us an email and tell us about the property, and we’ll send you a clear quote.
Will you come out to Hawkley?
Yes, we do. Our work covers London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
When is the sealant fully cured?
Most sealants are touch-dry well before they’re fully cured. We’ll tell you how long to leave the joint.
Can you quote for more than one area?
Of course. Doing several areas at once is usually more efficient, so mention them when you ask for a quote.
Do you do commercial work?
Yes. We work in offices, washrooms, hotels and other commercial premises. Working times can be discussed when we quote.
What should I tell you?
Only a few details: the address or postcode, what’s wrong and any access issues. Then phone 0345 464 0079 or send us an email.
Can new sealant go on top of the old bead?
No. Sealing over old sealant looks fine for a few weeks, then lifts. All the old sealant comes out before work begins.
How do I get a quote for new build mastic in Hawkley?
There’s no set price, as it depends on the job: how much there is, what’s there now, how we reach it and what it needs. We agree the price before any work begins.
What affects the quote in Hawkley
Jobs vary more than people expect. What affects the quote:
- How many rooms, windows or areas are involved
- The old material and how stubborn it is
- Working hours on commercial sites
- The type of sealant required
Combining jobs into one visit is usually more efficient than separate visits, so tell us about everything that needs sealing. You’ll get one clear quote for the whole job.
What to tell us for a quote
A few details help us give you an accurate quote. When you ask for a quote, tell us:
- Access, such as stairs, a lift or height
- The address or postcode of the job
- Roughly how big the job is
- Whether it has been sealed before
Every job is quoted individually, so start by telling us what you need. Just ring 0345 464 0079 or send us an email with the details and send photos if you have them.
What we can’t put right
We’ll always be straight with you, so here’s what sealant can’t fix:
- Structural cracks in walls or ceilings
- A tray or bath that is not properly supported, until it’s fixed
- Cracked trays, tiles or worktops
If in doubt, ring 0345 464 0079 or drop us an email and we will say what we think before you book.
Joints and surfaces we work on
- Windows & doors
- Plot handovers
- Kitchens
- Bathrooms & en suites

What we are called out for in Hawkley
When the heating goes on in the first winter, the house dries fast. Gaps open along skirting, frames and worktops and cracked sealant shows up.
Any of these means the joints need attention:
- Smeared, uneven beads picked up at snagging
- Skirting joints opening in the first winter
- Second-fix sealing on new plots
- Shower seals failing in the first year or two
If you’ve bought a new home near Liss station, the sealant around baths, showers and frames is worth checking in the first year or two.
What to look for in a quote
- What product goes in the joint
- What happens if the job turns out different
- How long to leave it before use
- The length of the guarantee
How to look after the new joints
A little care helps the new joints last. We recommend:
- Raise failed sealant with the developer while you’re covered
- Resist patching a failed seal with a tube from the DIY shop
- Avoid scourers and strong chemicals on sealant
- Wait for the cure time before using a resealed shower
Avoid standing on the rim of the bath or the edge of the tray. If a bath or tray moves when you stand in it, get it looked at.
The sooner you deal with untidy or cracking sealant, the less there is to put right. Left alone, a small crack can become a leak in a busy bathroom.
