How we handle new build mastic in Iffley
Some new-home owners let the house settle before resealing. For small cosmetic gaps, that’s reasonable, but a failed shower or bath seal shouldn’t wait. We work on kitchens, plot handovers and windows & doors, and the jobs we see most are cracks appearing as a new home settles and cracked sealant around new window and door frames.
In and around Iffley, floors range from older timber boards to tiles and newer finishes, 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.
A one-year guarantee comes as standard, so you are not left on your own once the job is done.

Landlord and commercial work in Iffley
Mouldy or split sealant often shows up at the end of a tenancy, and it’s easy to sort out between tenants. Several properties can be quoted together.
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.
Why deal with it now?
Running a new bead over the builder’s sealant might look tidy for a few weeks, but it will not bond to the old layer. Taking it all out and starting again is the only way to get a lasting seal. Around Iffley, water from a failed joint in an older home can soak into timber and plaster, which is far harder to put right than the sealant itself.
Leaving a failed joint usually makes the job bigger, not smaller, as water and mould keep getting in. If you are not sure whether it needs doing, phone 0345 464 0079 or email us for an honest opinion and a quote.

What sealant work cannot fix
It helps to know what we can’t do:
- Your warranty claim itself, which is between you and the builder
- Cracking that points to a structural problem
- Movement caused by a poorly fitted tray or bath
If you’re not sure, just phone 0345 464 0079 or send us an email and we will give you a straight answer.
What we seal
- Bathrooms & en suites

What affects the cost of new build mastic
We quote each job individually. This is what makes a difference:
- Any mould that needs treating
- How much old sealant there is and how hard it is to remove
- How easy the joints are to reach
- The product the joint needs
What you pay reflects the work, not guesswork. That is why we ask a few questions first and agree the price before starting.
Asking for a quote
To make quoting easier, let us know:
- Photos by email, if that’s easy
- Whether it has been sealed before
- Where the property is
- Whether it’s a home or a business
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, phone 0345 464 0079 or email us.

How much does new build mastic cost in Iffley?
We do not publish prices, because the cost 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.
Is there a guarantee?
Yes. All our work carries a 12-month guarantee.
When is the best time to reseal in a new build?
It depends on whether water is getting through. Failed seals in wet areas need doing now, while small cosmetic gaps can wait a while.
Is it normal for sealant to crack in a new home?
New homes dry out and move in their first couple of years, and sealant is often applied quickly onto dusty surfaces. Both lead to early failure.
How long should I leave it?
Most sealants are touch-dry well before they’re fully cured. We will give you the cure time for the product we used before we leave.
Can I do it myself?
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is.
If you are set on DIY, put the effort into 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.
New homes and floors in Iffley
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.

Different surfaces, different methods
Skirting and floors
Floors and skirting move as the house dries and the heating runs. We use a flexible product rather than caulk in a colour to suit.
Windows and doors
Draughts around new frames are often a sealant gap. We look at the joints and reseal where needed.
What happens on the day
Most of a good job is in the preparation, so that’s where we spend the time. Joints are cleaned back and dried before anything new goes in. All told, the work takes a few hours in a single home. For a job in Iffley, we agree the time, the access and parking before the day. Outdoor jobs depend on a dry day, since sealant needs a dry surface.
- 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.
- Joints are vacuumed and cleaned of building dust.
- Primer goes on where the surface and product need it, then the new sealant.
- Each bead is tooled and the cure times explained.
Preparing for the visit
- Mention any tricky access
- For indoor joints, keep the area dry beforehand if you can
- Plan for the work area to be out of bounds to pets and children
