Mastic sealing for businesses in Richmond upon Thames
Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.
Should maintenance staff do it?
What you see is the finished bead, but most of the work is hidden. Correct depth, the right primer and a sealant matched to the movement are where general trades tend to cut corners.
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.
Mastic sealing in Richmond upon Thames
Our clients include managing agents, property factors in Scotland, housing associations and landlords with block or commercial portfolios. A planned, building-by-building programme often works better than reacting to each complaint and we quote and schedule each building in turn. Site teams most often ask us about brittle perimeter mastic across a building and worn sealant at communal door frames, on external wall and movement joints, communal entrances and stairwells and shopfronts below residential blocks. A specialist sealant contractor works differently from a general builder: in Richmond upon Thames, that means joint design, primers and backing rod as standard.
For managing agents in Richmond upon Thames, resident access, notice periods and the building’s rules shape the job. We work to the agent’s notice and access plan, so residents know what’s happening.
Work we carry out comes with a 12-month guarantee. Should something we installed fail, speak to us on 01277 525 020 or email drawings and photos and we’ll come back to it.

How a job runs
Occupied buildings need a little choreography. We sign and contain the area we are in, keep walkways clear and move on in phases so staff and visitors can carry on around us.

- You get a fixed quote, per block or for the whole programme.
- We agree the programme and dates with you.

After the work
Every sealant joint needs some looking after, and their life depends on movement, exposure, cleaning and use. We suggest:
- Check sealant joints during planned building inspections
- Log resealing dates block by block
- Make it easy for occupiers to report draughts
- Share the asbestos register when you send details
Where a paintable product was specified, it can be painted after curing. Non-paintable silicone shouldn’t be painted over unless told otherwise.
Joints on a building age together so a single failure is a sign to check the rest. A planned reseal saves repeated visits.
Your questions answered
Do you take on jobs in Richmond upon Thames where loading and access are tightly controlled?
Yes, most London buildings have access rules of some kind, and we plan around them. Say when the building is occupied and when it’s quiet, and we’ll plan accordingly.
Can you quote for a block close to Richmond station?
Yes. Managing agents, landlords, property factors and housing associations are who this service is for. We work to your notice and access arrangements.
Do you cover Richmond upon Thames?
Yes. We cover Richmond upon Thames, within our coverage of Greater London, South East England and Scotland. To discuss a job, phone 01277 525 020 or send details through our quote form.
Do you check for asbestos in old sealant?
Asbestos removal isn’t part of our work. If old sealant is suspected, work stops until it’s tested, and the duty to manage asbestos sits with the dutyholder.
How long before the joints can be used?
Curing time varies by product, and we confirm it on the day, and sign any area that should be left alone.
Do you do block-wide mastic programmes?
Yes, planned programmes suit estates and portfolios. You get a fixed quote per building or for the whole job.
What about access for upper-floor joints?
We talk through access for each building when we quote. Tell us the number of storeys and whether scaffold or other access is planned and we’ll confirm the approach in the quote.
What sets the cost
Your fixed quote is built from the real scope. It takes account of:
- How accessible the joints are
- Whether the work must be split into stages
- Site requirements such as inductions and permits
- The total length or number of joints
Whether it’s a single area or a whole estate, the same things set the price: scope, access, product and programme. Call for a quote and we will put a fixed figure on it.
Before you send an enquiry
A few photos plus some basic facts will normally do. It helps to include:
- The product your specification calls for
- Any dates the work must fit around
- Whether an asbestos survey exists
- Drawings or a marked-up plan, if available
Need a figure for a tender or a budget? Send the scope and any drawings, and we will return a fixed quote that you can work with. If you have questions first, call 01277 525 020 or send details through our quote form.
Leave it or put it right?
Dealing with failed joints one report at a time is slow and scattered. Planned resealing covers a whole building or estate in one go and is simpler to manage and budget. Access in London is hard enough to arrange once, so it makes sense to deal with every failing joint while access is in place.
Every site prices differently: the joint sizes, the specified product, access and working hours each have a bearing. A fixed quote follows once we understand the job.
What you get with us
- Work carried out by CSCS-carded applicators
- CHAS accredited

When something else is needed
Some faults sit outside our scope, and we say so rather than covering them up:
- Asbestos-containing sealant, which we don’t remove
- Substrate edges that need repairing first
- Broken glass or failed sealed units
If in doubt, speak to us on 01277 525 020 or email a schedule or drawings and we’ll say what we think.

Planned mastic for Richmond upon Thames portfolios
In London, mastic work on a block goes through the managing agent or landlord, with notice to residents. We fit the programme to your notice periods.
If you are responsible for a building such as Holy Trinity Richmond, frame and door mastic needs the same attention as any other property. Property owners at sites such as Kew Retail Park, 1.4 miles north-east of Richmond upon Thames, can have mastic renewed between lettings. If you look after a block within reach of Richmond station, less than half a mile to the north-west of Richmond upon Thames, frame and balcony mastic can be renewed on one programme.
