About our construction mastic in Monken Hadley
Refurbishment work needs a slightly different approach from new build. Existing joints have to be stripped back to sound faces, because fresh sealant can’t key into cured silicone and the asbestos survey is checked first on older stock. New and existing joints then get the same preparation. If you have a mastic package split between trades with no clear owner and window and door perimeters that won’t pass inspection, we can put it right, on internal decorators’ caulk, brick and block movement joints and window and door perimeters alike. A specialist sealant contractor works differently from a general builder: on jobs in Monken Hadley, preparation and product choice get the time they need.
The ULEZ covers the whole of Greater London, so contractors’ vehicles on a job in Monken Hadley must meet its standards or pay the daily charge. Alongside that, sites normally need booked deliveries and a plan for where materials go.
We stand behind the joints we seal: 12 months, guaranteed. That covers our preparation and application, and if something we did falls short, we return to it.

What we can’t put right
Not every problem is a sealant problem, and we’re upfront when that’s the case. It won’t fix:
- Defective windows, doors or glazing units (the supplier or installer’s job)
- Designing joint widths or choosing the specification (that sits with the designer)
- Frame gaps too wide for sealant, which the installer needs to correct
Not sure which it is? You can give us a call on 01277 525 020 or use the quote form and we’ll tell you honestly before you book.

Common problems we fix in Monken Hadley
Dust is the enemy of adhesion on a construction site. Plaster dust, release agents, protective film residue and damp all stop sealant bonding so faces get cleaned, and primer goes on wherever the maker specifies, even on new work.
Any of the following is a good reason to get the joints checked over:
- Failed sealant in an existing building being refurbished
- External joints sealed in damp or cold conditions that are now failing
- Different trades sealing to different standards
- Sanitary sealant damaged by following trades
When a college such as Oak Hill College (2.7 miles south-east of Monken Hadley) builds or refurbishes, the mastic package normally has to fit around students and staff.

What affects the price in Monken Hadley
Sealant work doesn’t have a standard rate, since sites vary so much. What we look at:
- Phasing around occupants
- The product specified
- How accessible the joints are
- Distance, for remote addresses
We don’t publish prices, because the scope varies so much from one building to the next. Call for a quote.
What to include in your enquiry
A few photos plus some basic facts will normally do. Please tell us:
- The product your specification calls for
- Approximate linear metres or a joint schedule
- The type of building and who uses it
- How the joints are reached, and at what height
To get a fixed quote, ring 01277 525 020 or send details through our quote form. You can also send details through our quote form.
Aftercare for building managers
For the best life from the joints:
- Release areas for mastic once other trades have finished in them
- Keep product details for future maintenance
- Keep finished joints away from paint, plaster and scrapers
- Check frame gaps are within the sealant’s range before sealing
Brief the sparkle clean so they don’t scrape the new joints. Blades and abrasive pads are the commonest cause of damage at the final clean.
Frames with gaps too wide for sealant need sorting before the mastic goes on. Sealant stretched over an oversized gap won’t last. We raise them during our first walk of the area.
Monken Hadley: questions and answers
Can you take on a job at a hospital such as Barnet Hospital?
Yes. We work in healthcare settings as well as offices and schools. We follow the site’s permits, sign-in and infection-control procedures in every area.
Do you take on jobs in Monken Hadley where loading and access are tightly controlled?
Yes, most London buildings have access rules of some kind, and we plan around them. Send the building rules and access times with your enquiry. The ULEZ covers the whole of Greater London, which we allow for
What’s the quickest route to a quote?
The quote form is the simplest route, though you can also call the office on 01277 525 020 or email the details over. Photos, drawings or a joint schedule help us quote quickly.
Does weather matter for sealant work?
It can, when the joints are outside. Wet joints and cold, damp or frosty conditions stop the sealant bonding properly, so we watch the forecast and rearrange outside work if we have to. Internal work is far less affected.
Do you seal on top of existing sealant?
No. We cut the old material out and clean the joint back before sealing, because fresh silicone will not bond with aged silicone.
Do you install fire-rated sealant as part of a package?
We install fire-rated sealant where it is the specified product. If the detail calls for collars, wraps or batts instead, we will tell you.
Can you follow the specification on our project?
Yes. We follow the specification, along with the manufacturer’s installation guidance.
How the job changes by surface
Snagging before handover
Snagging is often the final mastic stage. We can work through the snag list area by area.
Fire-rated sealant where specified
Where the specification calls for fire-rated or intumescent sealant around service penetrations or linear gaps, we install it to the manufacturer’s tested detail. Fire stopping design belongs to the designer and building control and we install what’s specified.
