Photos, a specification or a quick description of the joints is enough to start a fixed quote.
What the job involves on each surface
Window and door perimeters on blocks
Window and door perimeters are where most mastic failure shows. Old perimeter mastic is removed, the joint prepared and new sealant tooled in.
External movement joints
Movement joints are cleaned out, backed with rod and resealed with a sealant of the right movement class.
Mastic sealing for commercial buildings in Regents Park
Treatment starts with a proper look: what has failed, what caused it and whether new sealant will actually solve it. Failed mastic is stripped, the faces taken back to sound material, primed where the manufacturer specifies and resealed and backing rod used wherever a joint is deep. If you have a mix of products and colours from past repairs and failed external movement joints, we can help. Whether you call it commercial sealant work, mastic application or joint sealing, in Regents Park it comes down to the same thing: the right product in a properly prepared joint.
Older buildings and conversions around places like Regents Park mix old masonry with newer frames. Perimeter joints need a sealant that suits both frame and masonry.
Our 12-month guarantee is about workmanship, not wear and tear. How long a sealant joint lasts depends on movement, exposure, cleaning and use, so we spell out the cover before we begin.

What we can’t put right
Being straight saves everyone time. Fresh joints won’t solve:
- Asbestos-containing sealant, which we don’t remove
- Failed window or door frames, which need a window contractor
- Water coming in from the roof or rainwater goods
Not sure which it is? You can call the office on 01277 525 020 or email the details over and we will tell you honestly.
Where we work in Regents Park
- External wall and movement joints
- Balcony and threshold joints
- Communal entrances and stairwells
- Window and door perimeters on blocks
- Communal kitchens and washrooms
- Shopfronts below residential blocks
Keeping the joints sound
Problems stay small when the joints are checked regularly. Specifically:
- Make mastic part of routine maintenance checks
- Look at the sunniest and most exposed elevations first
- Share your contractor requirements early
- Protect low-level joints in entrances
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.
Budgets are easier to plan when sealant is part of planned maintenance. A programme can start with the worst buildings so spending is spread.
On site: what to expect
Working in a building that stays open takes some planning. We sign and contain the area we’re in, keep walkways clear and work section by section so the rest of the building stays in use. Several jobs near Regents Park can be grouped on one trip. Tell us your site hours and we’ll plan around them.
- First we look at the mastic on each building and note what needs replacing.
- We send a fixed quote that sets out the joints, the products and the programme.
- The programme is fixed with you, including dates you can pass on to residents or tenants.
- Failed mastic is removed and the faces taken back to sound, dry material.
- Deep joints get backing rod, faces are primed if the manufacturer specifies it, then the joint is sealed and tooled.
- Completed joints are inspected and carry a 12-month workmanship guarantee.
Before we start on site
- Send any specification or drawings in advance
- Arrange parking or a loading space
- Point out any areas we must not close

Your questions answered
Will you take on work at estates like Liners Industrial Estate, close to Regents Park?
Yes. We cover Regents Park and the area around it, including industrial estates, business parks and retail parks such as Liners Industrial Estate. To start, just ring 01277 525 020 or email drawings and photos with the unit, the joints involved and your access times.
Can you work in a care home near Regents Park with residents in?
Yes. We work around residents’ routines, a room or two at a time. Noise and disruption are kept to a minimum.
How long does a job like this take?
We plan the time on site around your programme and access. You will have an expected duration with the quote.
What about access for upper-floor joints?
We talk through access for each building when we quote. Tell us the building height and any access already in place and we will confirm the approach in the quote.
What paperwork can you provide?
Our credentials include CHAS, Constructionline and public liability insurance. Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we’ll confirm with the quote.
When is resealing likely to be due?
Nobody can honestly give a figure in years, 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.
Can you quote from photographs?
Many jobs can be quoted from photographs, drawings or a joint schedule. If the job needs a look first, we’ll arrange a visit before quoting.
Signs you need mastic sealing in Regents Park
Buildings move with temperature and moisture, and the sealant takes up that movement. If the joint or the product wasn’t suited to the movement, it splits long before it should.
Things that usually lead to an enquiry:
- Damaged joints in communal entrances and corridors
- A mix of products and colours from past repairs
- Draughts at frames across a block
- Estate-wide sealant that is simply worn out
Older community buildings, Church of the Holy Trinity among them, often have frames of mixed ages whose mastic varies.
Comparing quotes
- Is the sealant right for the movement and the substrate?
- Their approach to joint depth and backing
- Whether primer will be used where the manufacturer specifies it
- Are they CHAS accredited or on Constructionline?
What happens if it’s left?
Leaving failed external joints lets water reach the structure behind. That can lead to damp, staining and damage to finishes and those cost far more to put right. In a smaller place such as Regents Park, getting a contractor back for a second visit takes time, so we’d suggest renewing all the joints that are going, not just the worst.
The product called for affects the cost, as does the preparation each joint needs. Access, phasing and site requirements come into it too.
Why appoint us
- Workmanship guaranteed for 12 months
- Specification-led, product-correct work
- Sealing commercial buildings since 2005
- A Constructionline member, so easy to vet

Planned mastic for Regents Park portfolios
Regents Park is within about 1 mile of the coast. On buildings near the shore, the side facing the weather usually needs its mastic renewed first; plan inspections around that. The South East is one of the drier parts of the UK. Outside work still depends on dry joints, and south- and west-facing elevations, which take the most sun and rain, often age first.
