New build mastic for homes and businesses in Headington Quarry
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. We work on plot handovers, skirting & floors and kitchens, and common reasons people get in touch are new-build shower sealant that has already split and second-fix sealing on new plots.
For a new home in or near Headington Quarry, it’s worth checking the sealant early. Gaps at skirtings, shower seals pulling away and missing mastic around frames are common snags.
We stand behind the work with a one-year guarantee, so you are not left on your own once the job is done.

What the job involves on each surface
Show homes
Tired or marked sealant in a show home can be renewed. We cut it out and reseal neatly.
Kitchens
Worktops in new homes can move slightly as the house dries, which opens gaps along the back. We reseal them with a flexible sealant.
Landlord and commercial work in Headington Quarry
Hotels need rooms back in use, so we plan the work room by room around your bookings where we can. We have worked in hotels as well as homes and businesses.

How to look after the new joints
Once the sealant has cured, a few habits help it last:
- Watch for new gaps as the house dries out
- Follow the cure time we give you
- Do not wait for the house to settle if water is getting through
- Photograph failed sealant before it’s redone
Clean the sealant with a mild detergent and a soft cloth. Keep scourers and harsh chemicals off it.
The sooner you deal with untidy or cracking sealant, the less there is to put right. Left alone, a small crack can become a leak over time.
What affects the cost of new build mastic
The quote reflects the job in front of us. We look at:
- Any working-time requirements on site
- Whether there’s mould to deal with
- The type of sealant required
- Whether old sealant or filler has to be cut out
There are no prices on our website, because the cost depends so much on the job itself. Call for a quick quote and we will talk you through it.

Headington Quarry questions
Is Headington Quarry in your area for new build mastic?
Yes. We work across London and the South East, and Headington Quarry is part of that. Just phone 0345 464 0079 or email us with a few details of the job, and we will give you a clear quote.
Will you come out to Headington Quarry?
Yes. Headington Quarry is within the area we cover, which takes in towns, villages and rural addresses. We work across London and the South East. Just mention lanes, gates or anything else about the route when you book.
Can you match the sealant colour to my new kitchen or bathroom?
It depends on the joint: white or clear for most sanitary joints, colours for worktops, floors and frames. We agree the colour before any work starts.
Can you reseal over the builder’s sealant?
No. Sealing over old sealant looks fine for a few weeks, then lifts. We remove every bit of the old bead before resealing.
Should I wait before resealing?
If the seal has failed and water is getting in, do it now. Small gaps that are just cosmetic can be resealed once movement has slowed.
What should I tell you?
Just the basics: where it is, what you’ve noticed and how we reach it. Then phone 0345 464 0079 or drop us an email.
Will the old sealant be removed?
Yes, every time. New sealant won’t bond properly to old, so the joint is cleaned back first.
When is the sealant fully cured?
Cure times vary by product and the temperature. We tell you how long to leave it before we go.
How it works
On the day, we look over the joints with you first. Surfaces next to the work are protected before any work begins. Most jobs take a few hours in a single home. For a job in Headington Quarry, we agree the time, the access and parking before the day. If the work is outside, the weather plays a part, as 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.
- We clean out the dust and grit left from the build.
- Primer goes on where the surface and product need it, then the new sealant.
- We tool every joint neatly and tell you when each area can be used.
How to prepare
- Let us know about stairs, lifts or work at height
- Let us know about parking restrictions
- Tell us about any water getting in
Getting a quote
Asking for a quote is easy: tell us what needs doing and where, and roughly how big it is. A few pictures by email make the job easier to understand, and we will come back to you with a quote.
Advice
When to call us in Headington Quarry
The wrong product is sometimes used in the wrong place: decorators’ caulk in a wet area, or a stiff sealant where there’s movement. Both fail early.
If you can see any of these, it’s time to have the joints looked at:
- Plot mastic for developers ahead of handover
- Messy sealant that spoils new finishes
- Skirting joints opening in the first winter
- Gaps behind new kitchen upstands
Around Headington Quarry, as everywhere, new build mastic is only as good as the preparation behind it.
What to look for in a quote
- Whether the sealant suits the joint
- Whether they seal over old material or remove it
- Whether VAT is included
- Whether they’re fully insured
When it isn’t the sealant
Sealant isn’t the answer to every problem, and we will tell you before work begins. It will not solve:
- Settlement cracks that need a surveyor
- Cracked trays, tiles or worktops
- A tray or bath that is not properly supported, until it’s fixed
If in doubt, phone 0345 464 0079 or drop us an email and we will say what we think before you book.
