New build mastic in Eastwood
For builders and developers, we work through plots to the schedule you give us. Bathrooms, en suites, kitchens, frames and skirting are sealed ready for handover with a sealant suited to each area. Typical jobs include kitchen sealant that has pulled off the wall and cracked sealant around new window and door frames, across show homes, bathrooms & en suites and windows & doors.
Where new homes go up in smaller places like Eastwood, it’s often a small development or a single plot. The sealant around baths, showers, frames and skirtings needs to be right from the start.
You get a one-year guarantee, the same in Eastwood as everywhere else we work.

How we quote for new build mastic
Jobs vary more than people expect. The main factors:
- The product the joint needs
- How many rooms, windows or areas are involved
- The size of the job
- The old material and how stubborn it is
There are no prices on our website, because each job is priced on what it involves. For a quick quote, please phone 0345 464 0079 or email us.
Asking for a quote
You don’t need to know the technical terms. Just tell us:
- Whether it’s a home or a business
- Photos by email, if that’s easy
- The rough size of the job
- Any access issues, like height or stairs
If you’re in Eastwood and need new build mastic, call 0345 464 0079 or send us an email. A short description of the job and where it is helps us quote, and we will agree the price before any work begins.
Why act early in Eastwood
A failed shower or bath seal in a new home lets water into floors and walls that are still drying out. Dealing with it early keeps the damage away from ceilings, floors and finishes. In a smaller place like Eastwood, 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.
Rather than a set price list, we look at what your job involves: how many joints, what’s in them now and how we reach them. You’ll know the price before we begin.
Why us?
- Over 20 years’ experience
- Old sealant always removed completely
- Tidy, careful work
- You choose the colour before work begins

What we do, step by step
Our applicators work methodically: protection first, then preparation, sealing and a tidy-up. For most jobs that takes a few hours for most snagging lists, longer for a run of plots, and the area is left clean. Parking around Eastwood is generally easier than in a town centre, but mention any lanes, gates or long drives. For outside work, side access and the height of the joints help us plan.
- 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, 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.
- We tool every joint neatly and tell you when each area can be used.
Before we arrive
- Let us know about stairs, lifts or work at height
- Mention any leaks or damp you’ve noticed
- Tell us about any previous sealing or DIY attempts

For new homes near Southend Airport station, it’s worth checking the sealant early, while snags are still fresh.

DIY sealant or a professional job?
A DIY attempt does not rule out a professional job. We cut it out and start again.
If you are set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it doesn’t work out, we can still put it right.

When to call us in Eastwood
New homes are full of moisture from plaster, screed and concrete, which takes a year or two to dry out. As it does, timber shrinks and joints open and the sealant has to cope with the movement.
It’s worth asking for a quote if you see:
- Gaps between new skirting and floors
- Shower seals failing in the first year or two
- Cracks appearing as a new home settles
- Internal frame sealant that has split
In and around Eastwood, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.
