How we handle construction mastic in Hammer Bottom
On refurbishments, the mastic package typically includes cutting out old sealant as well as sealing new work. Old beads come out completely, as fresh silicone can’t grip old. New and existing joints then get the same preparation. Most enquiries involve a mastic package split between trades with no clear owner and snag items on joints that need redoing before handover, across cladding and panel joints, window and door perimeters and floor and skirting junctions. Most enquiries from Hammer Bottom 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.
Construction in and around smaller places such as Hammer Bottom is often barn conversions, small groups of houses or extensions to halls and schools. Perimeters, facade joints and internal sealant all need doing properly, however small the scheme.
The 12-month guarantee is for workmanship rather than wear and tear. Sealant wears with time, and movement, weather, cleaning and use decide how fast, so we spell out the cover before we begin.

Questions we are asked in Hammer Bottom
Would you work within a site like Holy Cross Hospital?
Yes, provided the work is planned with the site’s estates team. The estates team’s permit system and infection-control rules come first, and the work is planned around them.
Will you take on work at estates like Kings Road Industrial Estate, close to Hammer Bottom?
Yes. We cover Hammer Bottom and the area around it, including industrial estates, business parks and retail parks such as Kings Road Industrial Estate. To start, just call the office on 01277 525 020 or email a schedule or drawings with the unit, the joints involved and your access times.
What does a mastic package usually include?
Window and door perimeters, internal decorators’ caulk where specified, sanitary joints, kitchens, movement joints and snagging. The scope follows your specification.
How long do sealant joints last?
There isn’t a single answer, since movement, weather, cleaning and use all affect it. Regular checks let you plan resealing before leaks or damage.
Can fire-rated sealing at service penetrations be included?
Where the specification calls for fire-rated or intumescent sealant around service penetrations or linear gaps, we install it to the manufacturer’s tested details. The design and sign-off belong to the designer, fire engineer or building control.
When can you be on site?
Mention the site’s hours and access windows in your enquiry, and we will schedule the work to suit. Our office runs Monday to Friday, 8am until 5pm.
Are you insured?
Yes. Mastic Doctor is fully insured, public liability included.
How the quote is worked out
We price every job individually. The things that drive the figure:
- Any access equipment needed
- Working within restricted access windows
- Travel to remote or island sites
- Specialist products, such as fire-rated or hygienic sealants
The product called for affects the cost, and so does the preparation, from cutting out to priming and backing rod. Access, phasing and site rules also count.
What we need to price the job
To price the job accurately, we need a clear picture of the site. Useful things to include:
- Anything awkward about access or site hours
- Clear photographs of the problem areas
- The asbestos register, for older buildings
- Any dates the work must fit around
A good quote starts with a clear picture: the joints involved, quantities, access and the product called for. Send what you have, and we’ll arrange a site visit if anything is unclear.

What else we do in Hammer Bottom
Maintenance after handover
Your facilities or cleaning team can help the joints last. Pass these on to them:
- Share drawings and the specification as soon as possible
- Check frame gaps are within the sealant’s range before sealing
- Use the product the specification names
- Don’t schedule sealing before decorators and flooring are done
Tell the builders’ clean team which areas have new sealant. Scrapers used on frames and worktops can nick or lift a new bead.
Sanitary joints that fail early become defects soon after occupation. Leaks behind showers and basins damage finishes and floors. Getting the product and preparation right first time avoids that.
Should maintenance staff do it?
Using site staff can make sense for a small touch-up, but larger jobs are different: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.
For most general trades, sealant is a sideline. A specialist prepares properly, controls joint depth and picks a product with the right movement class, which is what makes a joint last.
What happens if it’s left?
Patching snags as they appear can feel quicker than a proper close-out. But one planned snagging pass through each area normally clears more for less disruption. We can run snagging as its own phase before handover. Converted and older buildings near places like Hammer Bottom tend to move, and aged sealant cracks. The right product, sized to the joint, copes much better.
Quantities, awkward access and phased working all shape the price. So do site requirements such as inductions and permits, along with the time of year for external work.

Construction mastic around Hammer Bottom: points for this area
Central London is about 41 miles from Hammer Bottom. Towns within reach of London tend to keep building, from flats to offices and schools, which keeps mastic packages in demand.

Extensions at sites like Holy Cross Hospital, 1.1 miles east of Hammer Bottom, normally sit beside working departments, and the mastic follows strict access rules.
