How we handle construction mastic in Boreham Street
Buyers, tenants and clients notice sealant lines long before they notice the structure. Untidy or missed joints are among the commonest snag items. We seal so the snag list stays short. The enquiries we see most involve different trades sealing to different standards and old sealant on a refurbishment that needs stripping before new work, on cladding and panel joints, sanitary and kitchen joints and brick and block movement joints. Whoever orders the work in Boreham Street, the brief is normally the same: a clear scope, tidy work and joints that don’t fail again.
Around smaller places like Boreham Street, building work normally means conversions of farm buildings, a few new houses or an extension to a hall or school. Each still needs a proper mastic package: window perimeters, facade joints and internal sealant to the specification.
A 12-month guarantee applies to all our work. If an installation problem shows up, call the office on 01277 525 020 or email drawings and photos and we’ll arrange a return visit.

Our process
When we get to site, we report to your site contact and complete whatever induction the building runs. Floors, finishes and fittings next to the joints are covered before anything is cut or cleaned, and the work typically takes a few days on a modest refurbishment and longer on multi-plot or multi-storey schemes. If others near Boreham Street need work, visits can be combined. A fixed quote is given before anything starts.
- First we look at the scope on site or from drawings.
- A fixed quote sets out scope, products and phasing.
- Site paperwork is confirmed and our CSCS-carded applicators are inducted.
- Sealing follows the programme as areas are released.
- Any frame gaps or issues outside our scope are flagged to the site team.
- The package is closed out, snags cleared and backed by our 12-month guarantee.
Before we start on site
- Point out any areas we must not close
- Tell us your opening times and when work is allowed
- Tell staff and tenants when we will be in

What else we do in Boreham Street
New build and refits around Boreham Street
Boreham Street is in the South East, one of the UK’s drier regions. Winter mornings still bring frost and condensation on frames and panels, which is why external dates are agreed with the site manager. Boreham Street is about 47 miles from central London. Building activity in the commuter belt runs from new flats near stations to business park refurbishments, which keeps mastic packages in demand.
For a contractor at a hotel such as White Friars Hotel (under half a mile west of Boreham Street), the mastic often has to be finished before a reopening date.
Boreham Street is about 5 miles north-west of Bexhill-on-Sea, in East Sussex. Anywhere in BN27, the process is the same: details in, fixed quote out, then sealing and a 12-month guarantee.

When to call us in Boreham Street
Three-sided adhesion is a frequent fault on new work. Fixed to three faces, the sealant rips the first time the joint opens, so depth is controlled with backing rod or bond-breaker tape.
Most enquiries start with something like this:
- A long mastic snag list close to completion
- Missed perimeter joints on a new elevation
- Internal caulk splitting as the building dries out
- A mastic package split between trades with no clear owner
New wings at hospitals like Amberstone Hospital, 4 miles west of Boreham Street, bring long runs of window and panel joints to seal.
Questions to ask before you book
- Do they follow the manufacturer’s priming guidance?
- How joint depth will be controlled
- Are they CHAS accredited or on Constructionline?
- Will CSCS-carded applicators be on site?
Why deal with it now?
Some packages split mastic across the window fitter, kitchen fitter and plumber. The result tends to be uneven finishes and arguments about who should seal what. A single mastic package gives one point of responsibility and a consistent finish. Converted and older buildings near places like Boreham Street tend to move, and aged sealant cracks. A sealant with the right movement capability, correctly sized, lasts far better.
Every site prices differently: joint size, product, access and site hours all play a part. Send the details and a fixed figure follows.

Your questions answered
Is a hospital such as Amberstone Hospital somewhere you can work?
Yes. We work in healthcare settings as well as offices and schools. Work is phased so departments keep running, under the site’s own rules.
Is a smaller place like Boreham Street outside your area?
Not at all. Boreham Street is within our area. We cover Greater London and the counties of the South East. Send photographs and a list of what needs doing, and we’ll plan the job to need as few trips as possible.
Is it fine to apply new sealant on top of old?
No, never. Sealing over old material is one of the classic causes of early joint failure, so it all comes out first.
How do we ask for a quote?
The quote form is the simplest route, though you can also ring 01277 525 020 or send details through our quote form. Photos, drawings or a joint schedule help us quote quickly.
When is resealing likely to be due?
There isn’t a single answer, because life depends on how much the joint moves, how exposed it is and how it’s cleaned and used. Regular inspection is the best way to catch problems early.
How much does the work cost?
We don’t publish prices, because every site is different. With photographs or drawings, we can give you a fixed quote.
Can you handle several sites?
Yes. We take on portfolio and planned maintenance work, planned site by site to suit how each building is used.
When to bring in a specialist
Redoing a failed joint typically costs more than getting it right at the outset, since all of it has to come out and the faces be cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.
For most general trades, sealant is a sideline. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint.
What affects the price in Boreham Street
To price the job, we consider:
- Which sealant the job calls for
- How accessible the joints are
- Travel to remote or island sites
- How much there is to seal
Whether it’s a single area or a whole estate, the same things set the price: what’s in scope, how we reach it, what’s specified and when it needs doing. Call for a quote and we will put a fixed figure on it.
Sending details for a quote
However big the job, the same details help:
- The product your specification calls for
- Approximate linear metres or a joint schedule
- What the building is and how it’s used
- How the joints are reached, and at what height
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.
After the work
After handover, these steps help:
- Share drawings and the specification as soon as possible
- Put any product change through the designer first
- Release areas for mastic once other trades have finished in them
- Don’t force external sealing on a damp or frosty day
Any damage after we’ve finished should go on the snag list right away. Snags can be picked up in a planned close-out visit, priced as part of the package or separately.
Leaving the mastic snag list to the end squeezes everyone. A planned close-out through each area as it completes keeps the list short.
