Mastic sealing in Holbrook
Different joints need different sealants. Window perimeters and external joints often take a low-modulus neutral-cure silicone, while hybrid polymer sealants grip many materials and are often paintable, and colours are confirmed for whichever product is used. If you are dealing with estate-wide sealant that is simply worn out and communal area joints that look neglected, we can help, whatever the surface. Facilities teams, main contractors and managing agents in Holbrook tend to want the same three things: a clear scope, tidy work and joints that don’t fail again.
Rural conversions near places like Holbrook often set modern frames into older stone, flint or brick. 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. It doesn’t extend to damage, faults in the building or work by others, and we’re upfront about that.

Surface by surface
Commercial and mixed-use buildings
Where retail and residential share a building the programme has to suit everyone. We plan around the site hours and access windows you give us.
Planned maintenance
Mastic wears out like any building component; how fast comes down to movement, weather, UV and the product. Inspecting joints regularly keeps programmes on track.

Honest limits
Before quoting, we check that sealant is the right answer. It won’t put right:
- Leaks through the frame itself rather than the perimeter
- Glazing that needs replacing
- Asbestos-containing sealant, which we don’t remove
Not sure which it is? You can call 01277 525 020 or email us and we’ll tell you honestly before you book.
Surfaces we seal

General trades versus a specialist
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.
Some joints are best left to specialists: for instance fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. Getting these wrong normally costs more in the end than doing them right.
Common questions from Holbrook clients
Can you quote for a block close to Warnham station?
Yes, and several blocks can go on one quote. Photos of each elevation help us quote accurately.
Can work in a care setting near Holbrook go ahead while residents are there?
Yes. Care settings are planned area by area, at times agreed with the home. Any site rules, from signing in to infection control, are agreed before we start.
What paperwork can you provide?
We are CHAS accredited, a Constructionline member and carry public liability insurance. For specific documents, tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we’ll confirm with the quote.
Can you work to our specification?
Yes. Send it with your enquiry, and the quote will be based on it.
What if the old mastic contains asbestos?
We don’t remove asbestos-containing materials. If old sealant is suspected, work stops until it’s tested, and the duty to manage asbestos sits with the dutyholder.
How long does a typical visit take?
It depends on the scope, though a typical visit usually takes a few days for most blocks, with larger programmes scheduled building by building. Larger or phased jobs take longer, and we will give you a timescale with the quote.
Can you reseal a whole block or estate?
Yes. We survey and price each building, then work through them in order, and the programme can start with the worst.
Why it’s worth doing now in Holbrook
Replacing mastic before water gets in is a planned job. Once water has tracked in, the repair list grows and occupiers notice. Older rural buildings around Holbrook move with the seasons, and rigid or tired sealant can’t keep up. A sealant with the right movement capability, correctly sized, lasts far better.
There’s no price list, since every building and every scope is different. For a fixed figure, call for a quote and we’ll price your job on its own details.
