Share the site address and what’s failing, and we’ll reply with a fixed quote or arrange a visit.
Keeping the joints sound
Sealant joints are maintenance items, and their life depends on movement, exposure, cleaning and use. We suggest:
- Make it easy for occupiers to report draughts
- Mention RAMS, insurance or CSCS requirements up front
- Track which buildings were done and when
- Check the asbestos register before any old mastic is disturbed
Keep bins, bikes and deliveries away from low-level joints where you can. Damage at low level is the most common reason communal joints fail early.
Leaks at window perimeters spoil finishes and can affect frames. Resealing early keeps the job small.
Mastic sealing in Pimlico
In buildings from before 2000, some old mastics contain asbestos. Before we disturb it, we ask to see the asbestos register or survey and if it’s suspected, work stops until it’s tested. Removing asbestos-containing material isn’t something we do. Most enquiries involve repeated reactive repairs to the same buildings and damp patches beside frames, on communal kitchens and washrooms, window and door perimeters on blocks and balcony and threshold joints. Facilities teams, main contractors and managing agents in Pimlico tend to want the same three things: a fixed quote, no surprises on site and a 12-month guarantee behind the result.
Around smaller places like Pimlico, older walls fitted with newer windows are a familiar sight. The mastic needs to suit an irregular masonry face and the look of the building.
Whoever the client is, the cover is the same: twelve months on the work we carried out. Faults in the structure, damage and other trades’ work fall outside it, and we say so plainly.

Mastic sealing in Pimlico: the local picture
Central London is about 21 miles from Pimlico. Within reach of London, blocks run by agents and associations are common around stations; their frame mastic often ages block-wide. Rainfall across the South East, Pimlico included, is lower than in many parts of the UK. Outside mastic still needs a dry joint and the right temperature, and south- and west-facing elevations, which take the most sun and rain, often age first.
Blocks of flats and mixed-use buildings often cluster around stations such as Kings Langley station, 1.9 miles to the south-west of Pimlico, and their window and balcony mastic tends to age at the same rate across a building. For owners of several units at places like Kings Park Industrial Estate, which lies south-west of Pimlico, one programme can deal with frame and external mastic across the lot. Churches, halls and community buildings such as Church of the Ascension are looked after by trustees and committees like any other owner, and their frames, doors and external joints need mastic renewed in time.
Pimlico is about 2 miles south-east of Hemel Hempstead, in Hertfordshire.

Cost factors for mastic joints
We price every job individually. The main factors are:
- Backing rod, priming and other preparation
- Any access equipment needed
- The total length or number of joints
- Whether old sealant has to be cut out first
The work involved drives the cost: stripping out, preparation, sealing, access and phasing. Call for a quote.
Before you send an enquiry
The more we know, the firmer the quote. Helpful details to send:
- What the building is and how it’s used
- A wide shot and a close-up of the area
- Access details, including height
- Specification clauses that apply
Specifications, drawings and tender packages are welcome with any enquiry, and we will price against exactly what is specified. Smaller jobs need nothing more than photos and a few notes.
Why it’s worth doing now in Pimlico
Leaving failed external joints lets water reach the structure behind. That can lead to damp, staining and damage to finishes, which is harder to deal with than resealing. Converted and older buildings near places like Pimlico tend to move, and aged sealant cracks. The right product, sized to the joint, copes much better.
Pricing mastic joints depends on quantities, condition and access, plus any specification you are working to. Call for a quote.

Questions about Pimlico
Will you take on a block within reach of Kings Langley station?
Yes. Blocks of any size are within what we do. Photos of each elevation help us quote accurately.
Is Kings Park Industrial Estate, near Pimlico, within your area?
Yes. We cover Pimlico and the area around it, including industrial estates, business parks and retail parks such as Kings Park Industrial Estate. Photos and a short description are enough for a first look.
Is asbestos a concern with old mastic?
In older buildings, old mastic can contain asbestos. We check the asbestos register or survey before disturbing it and suspect material is tested first.
Will residents or tenants be disturbed?
Occupiers stay in the building throughout. If any flats or units need access, we will tell you in advance so it can be arranged.
Who decides which product is used?
The specification comes first, if there is one. If there isn’t one, it comes down to the joint: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.
Is it fine to apply new sealant on top of old?
No, never. Overlaying old sealant is a frequent cause of early failure, so it all comes out first.
When can the area be used after sealing?
The product and site conditions decide that. Some products skin over quickly but need longer to cure fully, and we confirm it before leaving site.
What the job involves on each surface
Estate-wide resealing programmes
Housing associations and agents often manage many similar blocks. Each block is priced and scheduled in order.
Planned maintenance
How long mastic lasts depends on exposure, movement and the product used. Regular inspection is the best way to plan resealing.
Diagnose, treat, sign off
Where the site stays busy, we agree a sequence with your contact so the disruption stays in one area at once. Each area is protected, prepared and sealed, then handed back before the next one starts. For work around Pimlico, we aim to finish in one visit, so we ask for photos and rough sizes first. That way the right products come on the day.
- Each block or building is walked and the failed joints recorded with the likely cause.
- A fixed quote follows, split by block or building if that suits you.
- 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.
- Deep joints get backing rod, faces are primed if the manufacturer specifies it, then the joint is sealed and tooled.

What we need from you
- Tell us what induction or permit system the site runs
