FAQs for Lordswood
Can you do new build mastic in Lordswood?
Yes, Lordswood is within the area we cover. We work across London and the South East. Just call 0345 464 0079 or send us an email with a few details of the job, and we’ll give you a clear quote.
Do you cover smaller places like Lordswood?
Yes, we do. Our work covers London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
Will you just run a new bead over the existing one?
No. New silicone will not bond to old silicone, so sealing over the top fails quickly. We cut the old bead out completely.
Is the work guaranteed?
Yes. Every job comes with a one-year guarantee.
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 does not work out, we can redo it.
Can you do plot mastic on a new development?
Yes. We work through plots to your schedule, room by room. Tell us the plots and the joints involved for a clear quote.
Do you have insurance?
Yes. We are fully insured.
Do you use white or clear sealant?
Most bathroom joints are white or clear, but sealant comes in other colours too. We match the colour to the finish and agree it with you.
About our new build mastic in Lordswood
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 skirting & floors, windows & doors and kitchens, and the jobs we see most are gaps opening as the house dries out and settles and shower seals failing in the first year or two.
Homes around Lordswood range from older cottages to newer houses, and their floors range just as widely, from timber that moves with the seasons to tiles laid on concrete. The sealant at skirtings and thresholds has to suit the floor it meets.
The work is guaranteed for twelve months. If something is not right with it in that time, tell us and we’ll put it right.

New homes and floors in Lordswood
Lordswood is close to the coast. New homes near the sea put their outside mastic to work from day one, so it’s worth checking at snagging. The South East is one of the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
If you’ve bought a new home near Millbrook (Hants) station, the sealant around baths, showers and frames is worth checking in the first year or two.
Lordswood is about 2 miles north-west of Southampton, in Southampton. Whether you are in the middle of Lordswood or further out, we cover new build mastic for every kind of property. Our area takes in 40 places across Southampton.
Work in SO16 and SO15 works the same way as everywhere else we cover. Local streets include Peach Road, Linden Road and Woburn Road. Neighbouring places we cover for new build mastic include Coxford (1 mile south-west), Bassett (1 mile east), Rownhams (1 mile north-west), Maybush (1 mile south-west) and Chilworth (1 mile north-east). Further out, we also cover Townhill Park (3 miles east), Midanbury (3 miles east), Thornhill (5 miles south-east), Chartwell Green (4 miles east), Harefield (4 miles south-east) and Itchen (4 miles south-east).

What we’re called out for in Lordswood
Not every new-build joint gets the right sealant: caulk where water collects, or a rigid product on a moving joint. Both fail early.
Any of these means the joints need attention:
- Beads laid onto grit and dust from the build
- Shower seals failing in the first year or two
- Cracked sealant around new window and door frames
- Kitchen sealant that has pulled off the wall
Around Lordswood, as everywhere, new build mastic is only as good as the preparation behind it.
What your quote should include
- Which sealant they’ll use, and why
- Whether they’re fully insured
- Who does the work, and how experienced they are
- How the colour is chosen
DIY versus a professional finish
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions, then guaranteed for a year.
If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it doesn’t work out, we can still put it right.
What sealant work cannot fix
We’ll always be straight with you, so here’s what new sealant won’t do:
- Leaks from pipes, valves or wastes, which need a plumber
- Settlement cracks that need a surveyor
- Damaged fittings that need replacing
Not sure which it is? You can call 0345 464 0079 or drop us an email and we will tell you honestly.
Joints and surfaces we work on

Why it’s worth doing now in Lordswood
Water getting past a failed seal in a new build reaches walls and floors that are still settling. Dealing with it early keeps the damage away from ceilings, floors and finishes. In a smaller place like Lordswood, wherever a wall is exposed, a failed outside joint is a real source of damp. Indoors, a failed seal lets water into floors and panels as it would anywhere.
Doing several joints on 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.

How it works
The work is kept neat and contained to the area we’re working on, so you can carry on as normal. Expect the work to take anything from a few hours to several days, depending on the number of plots, and we explain the cure time before we leave. For a job in Lordswood, we agree the time, the access and parking before the day. Outdoor jobs depend on a dry day, since sealant needs a dry surface.
- We look at why each joint failed, including any movement.
- Old sealant is cut out and the joints cleaned.
- We make sure the joints are dry and prime them if needed.
- New sealant goes in, with baths filled first so they’re at their heaviest.
- The finished joints are checked and the cure times given.
Before we arrive
- Try not to wet indoor joints just before the visit
- Plan for the work area to be out of bounds to pets and children
- For business premises, tell us about site rules or sign-in
