New-build mastic & snagging in Ramsdean, Hampshire
Professional new build mastic in and around Ramsdean, with every bit of old sealant taken out first.
- Messy sealant that spoils new finishes
- Shower seals failing in the first year or two
- Internal frame sealant that has split
New build mastic in Ramsdean
We carry out plot mastic and second-fix sealing for builders, and snagging reseals for new-home owners. Both get the same care over preparation, because that is what rushed new-build sealant normally lacks. If you are dealing with shower seals failing in the first year or two and joints pulling apart as timber shrinks, we can help, on bathrooms & en suites, plot handovers and windows & doors alike.
Around Ramsdean, older homes often have timber floors that move through the year, which is why skirting and threshold joints need a flexible sealant, not filler.
Each job carries a 12-month guarantee, whatever its size.

When to call us in Ramsdean
Sealant applied onto damp surfaces does not bond well. On a busy site, joints are not always given time to dry first.
Signs it’s time to call us include:
- Gaps between new skirting and floors
- Cracked sealant around new window and door frames
- New-build shower sealant that has already split
- Smeared, uneven beads picked up at snagging
In and around Ramsdean, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.

DIY sealant or a professional job?
Sealing over old silicone is the commonest DIY error. Silicone does not stick to old silicone, so it lifts and traps water and mould underneath. 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 need the right product, the right access and the right method.
How the visit works
On the day, there’s very little for you to do. Show us the job and we’ll take it from there. The job generally takes a few hours for most snagging lists, longer for a run of plots. Somewhere like Ramsdean 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.
- We start by going through the snagging items or plot schedule with you.
- The failed sealant is removed completely, with no layer left behind.
- Joints are vacuumed and cleaned of building dust.
- We prime where needed and apply a sealant suited to each joint.
- Each bead is tooled and the cure times explained.

FAQs for Ramsdean
Is Ramsdean within the area you cover?
Yes. Ramsdean is within the area we cover, which takes in towns, villages and rural addresses. We work across London and the South East. Just mention lanes, gates or anything else about the route when you book.
I let a flat near Petersfield station. Can you help?
Yes. We work for landlords and agents as well as homeowners, and several properties can be quoted together. You can ring 0345 464 0079 or send us an email with the details for a clear quote.
Can I do 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.
Do I have to be there?
Access is agreed with you when the job is booked. Indoors, that normally means someone at home.
Can I add another job to the visit?
Yes. Just list everything you need and you’ll get one quote.
Should I wait before resealing?
It depends on whether water is getting through. A leaking shower or bath seal should be redone straight away, but cosmetic gaps can wait for movement to slow.
My new home is still under warranty. Should I contact you?
Your builder, if you are still in their snagging or warranty period. If that does not work out, we are happy to quote with our 12-month guarantee.
Do you take on second-fix sealing for builders?
Yes. We seal plots to the developer’s programme, room by room. Tell us the plots and the joints involved and we’ll quote.
Work for landlords, hotels and businesses
In hotels, rooms out of use cost money, so the work can be planned room by room. We have worked in hotels as well as homes and businesses.
Housing providers, facilities teams and property managers book us too in Ramsdean and across Hampshire. Several sites can be quoted together, and we’re fully insured for the work.
Honest limits
Sealant is not the answer to every problem, and we’d rather say so up front. It won’t solve:
- Baths and trays that move too much for sealant to cope with
- Damaged fittings that need replacing
- Disputes or warranty claims with your builder
If in doubt, phone 0345 464 0079 or send us an email and we will say what we think.
What we seal
- Skirting & floors
- Bathrooms & en suites
- Show homes
- Kitchens
- Windows & doors
- Plot handovers
Different surfaces, different methods
Show homes
Bathrooms, kitchens and frames in show homes are sealed or resealed to a neat finish to a tidy standard. Tell us when the home is open so we can plan around it.
Skirting and floors
Where the floor meets a bath panel or kitchen plinth, the joint keeps mop water out. We seal them with a sealant suited to wet areas.
New build mastic in Ramsdean: local notes

Why it’s worth doing now in Ramsdean
A quick bead over the top of the old sealant can look fine at first, but it can’t bond to what’s underneath. Taking it all out and starting again is the only way to get a lasting seal. Where a wall is exposed, as many are in small places like Ramsdean, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
