What new build mastic looks like in Broadgate
Compared with the north and west, the South East gets less rain, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
If you’ve bought a new home near Chandlers Ford station, the sealant around baths, showers and frames is worth checking in the first year or two.

How we handle new build mastic in Broadgate
For builders and developers, we work through plots to the schedule you give us. We seal bathrooms, kitchens, windows, doors and skirting so plots are ready to hand over with a sealant suited to each area. We are often asked to deal with messy sealant that spoils new finishes and internal frame sealant that has split, on windows & doors, kitchens and skirting & floors.
Older homes in small places like Broadgate often have timber floors that move with the seasons, so skirting and threshold joints need a flexible sealant rather than a rigid filler.
The work is covered for a year after we finish. If there’s a problem with it, please call 0345 464 0079 or send us an email.

How it works
At the end, we look at the finished work together and tell you how long to leave it. The visit itself usually takes a few hours in a single home, depending on how much there is to do. Somewhere as small as Broadgate, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- We look at why each joint failed, including any movement.
- We remove the failed sealant and clean the joints.
- We make sure the joints are dry and prime them if needed.
- Baths are filled with water, then the new sealant is applied.
- The finished joints are checked and the cure times given.
Getting ready for the visit
- Try not to wet indoor joints just before the visit
- Clear items away from the joints we are working on
- Tell us about access, such as stairs, a lift or high-level joints

What affects the quote in Broadgate
Some jobs are bigger than they look, and some smaller. What affects the quote:
- The product the joint needs
- How many rooms, windows or areas are involved
- The size of the job
- Access and height
Rather than a set price list, 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.
Helping us quote
Before you ask for a quote, have a think about:
- If it’s domestic, commercial or a hotel
- Roughly how big the job is
- The problem you’ve noticed
- A few photos by email, if you can
Quotes start with a quick conversation. Tell us what’s wrong, where it is and how much there is, and we’ll explain how we’d tackle it. When it suits you, ring 0345 464 0079 or email us.
For landlords and businesses
Hotels need rooms back in use, so the work can be planned room by room around your bookings where we can. We have worked in hotels as well as homes and businesses.
Water getting past a failed joint can damage the building, which is a bigger problem in a rented property. Resealing at the right time is simple maintenance.
What we’re called out for in Broadgate
The wrong product is sometimes used in the wrong place: decorators’ caulk in a wet area, or a stiff sealant where there’s movement. Neither lasts long.
Look out for these signs:
- Shower seals failing in the first year or two
- Frame joints opening as the plaster dries
- Gaps opening as the house dries out and settles
- Sealant applied over dusty or wet surfaces
In and around Broadgate, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.
Questions to ask before booking
- Is VAT in the price?
- Is the old sealant removed completely?
- How hidden problems are handled
- The length of the guarantee
Why deal with it now?
Sealant done properly at handover means fewer callbacks. Every return visit for a failed seal takes time, and they’re avoidable with good preparation. In a small place like Broadgate, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
Every job is a little different, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all play a part, and we will explain the quote if you ask.

Take a look at how sealant jobs are priced and customer reviews.
Should I try it myself first?
Sealing over old silicone is the commonest DIY error. Silicone doesn’t stick to old silicone, so it peels away and traps moisture behind it. Everything old must be removed first.
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.
