New build mastic for homes and businesses in Ashington
Failed shower seals, gaps along the skirting and messy beads are common items on a new-home snagging list. If you’re still within the builder’s snagging or warranty period, tell them first and if that stalls, we can do it. We work on kitchens, show homes and skirting & floors, and people most often call us about gaps opening as the house dries out and settles and sealant that never bonded to the surface.
Around Ashington, older homes often have timber floors that move through the year, so skirting and threshold joints need a flexible sealant rather than a rigid filler.
Our work is backed for twelve months, in Ashington and everywhere else we cover.

DIY sealant or a professional job?
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
If you’re 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 does not work out, we can still put it right.
FAQs for Ashington
Do you cover Ashington for new build mastic?
Yes, Ashington is within the area we cover. We work across London and the South East. Just ring 0345 464 0079 or drop us an email with a few details of the job, and we’ll give you a clear quote.
Is there a guarantee on new build mastic in Ashington?
Every job comes with our 12-month guarantee, wherever it is. We are fully insured, and an ARBOMaster approved applicator.
Are you insured?
Yes. We are fully insured.
Will the old sealant be removed?
Yes. We cut out all the old sealant and clean the joint.
When is the best time to reseal in a new build?
Any seal that is leaking should be redone straight away. Cosmetic gaps can wait until the first year or two of movement has passed.
Can landlords and businesses book you?
Yes, we do. Domestic, commercial and hotel work are all part of what we do, and we’re fully insured.
Is there any odour?
There can be a smell while the sealant cures, but it fades. Opening a window helps.
I’m a tenant. Can you help?
We are happy to deal with the tenant, landlord or agent. Get your landlord’s agreement first.
Landlord and commercial work in Ashington
From a single let to a portfolio, you get the same standard of work: old sealant fully removed, joints prepared properly and a 12-month guarantee.
We also work for property managers and facilities teams. Several sites can go on one quote, and we’re fully insured for the work.
What happens if it’s left?
If you’re still in the builder’s snagging or warranty period, ask them to put it right first. If it keeps failing or isn’t dealt with, we can reseal it properly. Older cottages and farmhouses around Ashington can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
No two jobs are quite the same, so each one gets its own quote. Size, access and the product the joint needs all play a part.

What the job involves on each surface
Show homes
Show homes need sealant that looks right from day one. We lay neat, even beads in colours to suit the finishes.
Kitchens
New-kitchen sealant is often applied in a rush. We remove it and reseal with a kitchen-suitable sealant.
How it works
Every visit runs the same way: we check the joints, mask and protect the surrounding surfaces, do the work and tidy away. Most jobs take a few hours for most snagging lists, longer for a run of plots. In a small place like Ashington, access is usually the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We look at why each joint failed, including any movement.
- Old sealant is cut out and the joints cleaned.
- Joints are dried and primed where the product calls for it.
- Baths are filled with water, then the new sealant is applied.
- We check every joint and leave you with the cure times.
Preparing for the visit
- Mention any parking rules near the property
- Let us know if you’ve seen damp or leaks
- Mention if the joints have been sealed before
