How the job changes by surface
Windows and doors
On new builds, external frame sealant can be patchy. It’s resealed with an exterior sealant suited to the frame and wall.
Bathrooms and en suites
En suite showers are a common source of leaks into the room below. A proper reseal keeps water in the tray.
New build mastic in Milton Common, done properly
Dust is the enemy of new-build sealant. Each joint is cleaned of dust and primed where the product calls for it, so the sealant actually sticks instead of bonding to the dust. If you are dealing with sealant work across a run of new homes and skirting joints opening in the first winter, we can help, on kitchens, windows & doors and bathrooms & en suites alike.
Older homes in small places like Milton Common often have timber floors that move with the seasons, which is why skirting and threshold joints need a flexible sealant, not filler.
There’s a 12-month guarantee on every job, whatever its size.

Should I try it myself first?
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
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.
Milton Common questions
What guarantee comes with new build mastic in Milton Common?
All our work, in Milton Common and everywhere else, comes with a 12-month guarantee. We’re also fully insured and ARBOMaster approved.
Is Milton Common in your area for new build mastic?
Yes. We work across London and the South East, and Milton Common is part of that. Just phone 0345 464 0079 or drop us an email with a few details of the job.
Are you an approved applicator?
Yes. We are approved under the ARBOMaster scheme, the approved applicator scheme for Arbo sealants.
Can you do plot mastic on a new development?
Yes. Plot mastic and second-fix sealing for developers is part of our work. Send the schedule and any specification and we’ll give you a quote.
What sealant do you use?
Quality sealants from brands including Arbo and Everbuild, chosen to suit the joint. We will tell you what we’re using and why.
Do you remove the old sealant?
Always. Sealing over the old bead is the commonest cause of early failure, so we never do it.
Will it make a mess?
Very little: the area around the joints is protected first, and we clear up the old sealant and our materials before we leave.
I rent my home. Can I book you?
We can work for tenants, landlords or agents. Just make sure your landlord agrees.
Why deal with it now?
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. Around Milton Common, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
A few things move the cost up or down: how much old sealant there is and how stubborn it is, whether mould needs treating, and whether we need extra access for height. We take all of that into account in your quote.

How it works
On the day, we start by going over the job with you, so you know exactly what we’re doing. Surfaces next to the work are protected before any work begins. Most jobs take anything from a few hours to several days, depending on the number of plots. In a small place like Milton Common, access is normally the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- We start by agreeing which joints are on the list, from the snagging sheet or plot schedule.
- The old bead comes out in full, with no layer left behind.
- We clean off dust from the build and prime the surfaces where the product needs it.
- New sealant suited to each joint is applied and tooled neatly.
- Each area is checked and left with its cure time.
Getting ready for the visit
- Plan for the work area to be out of bounds to pets and children
- Where the joints are inside, avoid wetting them before we arrive
- Mention if the joints have been sealed before

Quotes start with a quick conversation. Tell us what’s wrong, where it is and how much there is, and we will explain how we’d tackle it. Whenever you’re ready, phone 0345 464 0079 or send us an email.
Advice
When to call us in Milton Common
Sealant is often one of the last jobs before handover. Dusty, unprimed joints are common, so the bead never bonds properly.
It’s worth asking for a quote if you see:
- Cracks appearing as a new home settles
- Messy sealant that spoils new finishes
- Sealant that never bonded to the surface
- Leaking shower tray seals in a new home
Whether the job is in Milton Common itself or nearby, the right material for each joint matters as much as a neat finish.
What to look for in a quote
- Which colour the sealant will be
- Who does the work, and how experienced they are
- Whether all the old sealant comes out first
- The length of the guarantee
Aftercare tips
A little care helps the new joints last. We recommend:
- Avoid scourers and strong chemicals on sealant
- Report sealant problems to your builder during the snagging period
- Avoid running a DIY bead over the old one
- Follow the cure time we give you
Leave the sealant for the cure time we give you before showering or bathing. Most silicones need around a day.
Report failed sealant to the builder while you’re in the snagging period. After that, putting it right may fall to you.
