Send drawings, photos or a joint schedule, or tell us about the site, and we’ll come back with a fixed quote.
Honest limits
Our job is the joint, not everything around it. Sealant alone won’t deal with:
- Water coming in from the roof or rainwater goods
- Cracked or crumbling render, brick or stone at the joint edges (we’ll tell you if so)
- Leaks through the frame itself rather than the perimeter
If in doubt, ring 01277 525 020 or email drawings and photos and we will say what we think before you book.
Where we work in Waterside
- Communal kitchens and washrooms
- Communal entrances and stairwells
- External wall and movement joints
- Balcony and threshold joints
- Shopfronts below residential blocks
- Window and door perimeters on blocks
How we handle mastic sealing in Waterside
On a residential block, the work happens around people’s lives. Dates, areas and the order of work are agreed with you in advance so you can let residents know what is happening. Communal entrances and stairs stay usable throughout. We work on balcony and threshold joints, communal entrances and stairwells and communal kitchens and washrooms, and what we are called in for most is brittle perimeter mastic across a building and repeated reactive repairs to the same buildings. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: in Waterside, that means joint design, primers and backing rod as standard.
Owners and agents with buildings around smaller places such as Waterside tend to manage small terraces of association properties, converted barns and commercial units. Mastic around frames and on external joints wears out in time, whatever the building.
What our 12-month guarantee covers is the way we did the job: the preparation, the sealing and the tooling. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

Questions we’re asked in Waterside
Is Waterside too small for you to travel to?
No. Places such as Waterside 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.
Can you quote for a block close to Amersham station?
Yes, we work for agents, landlords and housing associations with blocks of every size. Photos of each elevation help us quote accurately.
Is mastic sealing guaranteed?
There is a 12-month guarantee on our workmanship and we hold public liability insurance.
Will you just go over the old sealant?
No. Sealing over old material is one of the classic causes of early joint failure, so it all comes out first.
Is asbestos a concern with old mastic?
Some mastics in pre-2000 buildings contain asbestos. We check the asbestos register or survey before disturbing it and suspect material is tested first.
Can weather delay the job?
For external joints, yes. The joint has to be dry and within the product’s temperature range, so frost, rain or cold mornings can delay outside work. Internal work is rarely affected.
How long before the joints can be used?
The product and site conditions decide that. Some products skin over quickly but need longer to cure fully, so we’ll confirm the curing time on the day.
Blocks and managed buildings in Waterside
Rainfall across the South East, Waterside included, is lower than in many parts of the UK. Even so, frame mastic only goes on in dry, workable conditions, and elevations facing the sun and the prevailing weather are normally where frame mastic ages first. Waterside lies roughly 26 miles out from central London. Around the capital’s commuter belt, managing agents look after many blocks close to stations and town centres.
Landlords with units on estates such as Waterside Business Park (less than half a mile north-west of Waterside) can bring frame, door and external mastic across several units into one programme. For agents with blocks near Amersham station (1.6 miles south of Waterside), a block-wide mastic programme deals with frames, balconies and entrances in one go.

- Window mastic that has split and shrunk
- The same joint failures repeated across a portfolio
- Draught complaints from residents or tenants
- Old repairs sealed over failed mastic

From enquiry to sign-off
At the end of each section, the masking comes off, the area is cleaned and every joint is checked, ready for your sign-off. If an area should be left alone while the sealant cures, we say how long and put signs out. For a building around Waterside, tell us how to find it and who will meet us. Send that with the details and we’ll confirm the plan with the quote.
- Each block or building is walked and the failed joints recorded with the likely cause.
- We send a fixed quote that sets out the joints, the products and the programme.
- Dates, areas and access are agreed so residents or tenants can be told in advance.
- We remove the old mastic completely and clean the joint faces back.
- Backing rod and primer go in as the joint requires, then the new bead is placed and tooled.
- Finished joints are looked over and the 12-month guarantee confirmed.
Preparing the site

Advice
How the quote is worked out
The price varies from site to site. It mainly depends on:
- Specialist products, such as fire-rated or hygienic sealants
- Joint width, depth and condition
- Induction, permit and paperwork requirements
- Location, for remote and island sites
Access can matter as much as the joints themselves: easy-to-reach joints are quicker than those that need equipment to get to. Mention the access as part of your enquiry.
Details that help us quote
For an accurate fixed quote, we need a clear picture of the site. Useful things to include:
- What the building is and how it’s used
- Rough lengths or quantities, or drawings if you have them
- Your programme or deadline
- The asbestos register, for older buildings
Every job follows the same four steps: send details, get a quote, we seal, guaranteed. The first step is to give us a call on 01277 525 020 or use the quote form with what you know.
Why act early in Waterside
Sealing over failed mastic looks tidy for a while. It won’t grip the old sealant and soon comes away. Cutting out and resealing properly does it once. Converted and older buildings near places like Waterside tend to move, and aged sealant cracks. The right product, sized to the joint, copes much better.
The specified product makes a difference, and so does the preparation, from cutting out to priming and backing rod. Access, phasing and site rules also count.
