What we can’t put right
Our job is the joint, not everything around it. Sealant alone won’t deal with:
- Faulty frames rather than failed sealant
- Joints damaged after sign-off by following trades
- Specifying the product where the designer hasn’t
If you are not sure, just speak to us on 01277 525 020 or email drawings and photos and we’ll give you a straight answer before you book.
What we seal
- Brick and block movement joints
- Window and door perimeters
- Internal decorators’ caulk
- Cladding and panel joints
- Sanitary and kitchen joints
- Floor and skirting junctions
Construction mastic in Ellisfield
On a new build, the mastic package is one of the last trades through each area. Mastic Doctor takes on mastic packages for main contractors and developers with projects in Ellisfield, following the trades through the building as rooms and elevations become ready. We work on floor and skirting junctions, window and door perimeters and sanitary and kitchen joints, and what we are called in for most is different trades sealing to different standards and snag items on joints that need redoing before handover. Most enquiries from Ellisfield start with one failed joint and grow into a wider look at the building: we check the joints around it and give you an honest view of what needs doing now and what can wait.
Around smaller places like Ellisfield, building work usually means conversions of farm buildings, a few new houses or an extension to a hall or school. Perimeters, facade joints and internal sealant all need doing properly, however small the scheme.
Our 12-month guarantee is about workmanship, not wear and tear. Sealant wears with time, and movement, weather, cleaning and use decide how fast, so we’re clear about what is covered before work starts.

Common problems we fix in Ellisfield
On a live site, contamination is the biggest threat to a new joint. Plaster dust, release agents, protective film residue and damp all stop sealant bonding so faces get cleaned, and primer goes on wherever the maker specifies, even on new work.
Typical triggers for a call:
- Window and door perimeters that won’t pass inspection
- Snag items on joints that need redoing before handover
- Old sealant on a refurbishment that needs stripping before new work
- A mastic package split between trades with no clear owner
For a contractor working at a hospital such as Basingstoke and North Hampshire Hospital, 5.1 miles north of Ellisfield, perimeter and facade sealing is planned around patients and deliveries.

What the job involves on each surface
Bathrooms, en suites and washrooms
In bathrooms and washrooms, an anti-mould sanitary silicone goes around every fitting. Each joint is prepared, sealed and finished with a neat tooled line and baths are loaded where appropriate before sealing.
Fire-rated sealant where specified
Fire-rated sealant forms part of some packages, installed to the product’s tested detail where it is specified. Fire stopping design belongs to the designer and building control.

Common questions from Ellisfield clients
Can you work on a hospital site such as Basingstoke and North Hampshire Hospital?
Yes, healthcare and care buildings are part of our work. The estates team’s permit system and infection-control rules come first, and the work is planned around them.
Is Ellisfield off your patch?
No. Places such as Ellisfield are covered as much as the big towns. We work across Greater London and the South East. We plan jobs in smaller places so return trips are kept to a minimum.
When can you be on site?
Mention the site’s hours and access windows in your enquiry, and we will plan around them. You can reach the office between 8am and 5pm, Monday to Friday.
Do your applicators hold CSCS cards?
CHAS and Constructionline are both in place, and our applicators hold CSCS cards. Public liability insurance is in place.
Will you come and look before quoting?
Many jobs can be quoted from photos, drawings or a joint schedule. If the job needs a look first, we will arrange a visit before quoting.
Will you quote for a small job?
Single areas, one-off repairs and whole buildings are all quoted the same way: details, then a fixed price, then sealing, then a 12-month guarantee.
Is the mastic package guaranteed?
It’s backed by our 12-month guarantee on the workmanship. Keeping other trades off finished joints prevents most problems.
Aftercare for building managers
Cleaning and maintenance staff play a part too. Share these points with them:
- Plan external elevations with the weather in mind
- Don’t schedule sealing before decorators and flooring are done
- Ask for joint and product checks before the package is urgent
- Note which sealant went where at handover
Any damage after we’ve finished should go on the snag list straight away. Snags can be picked up in a planned close-out visit.
Leaving the mastic snag list to the end squeezes everyone. Clearing snags area by area spreads the work out and keeps handover on track.
New build and refits around Ellisfield
Ellisfield lies roughly 47 miles out from central London. Construction around the commuter belt mixes station-side flats with refurbished offices and units, and each scheme needs its mastic sealed to programme. The South East is one of the drier parts of the UK. Still, external mastic needs dry faces within the maker’s temperature limits, which isn’t every day, so external mastic is timed for workable conditions and agreed with the site manager.
For contractors refurbishing units at places like Viables Business Park, 2.6 miles north of Ellisfield, the mastic covers cladding panels, roller-door and window perimeters. With historic properties like Hall Place (to the south of Ellisfield) in the area, refurbishment work often meets old masonry that needs compatible sealants.
