Advice
Mastic sealing for commercial buildings in Dean Court
Most buildings come with mastic joints nobody has looked at since handover and it slowly wears out: window perimeters, door frames, external joints and communal junctions all rely on it. Once it cracks, hardens or comes away, draughts and water find a way in, and occupiers start reporting it. Most enquiries involve movement joints with sealant missing and mastic failing across several blocks on an estate, on balcony and threshold joints, external wall and movement joints and shopfronts below residential blocks. Looking for mastic applicators who cover Dean Court? Mastic Doctor has worked for contractors, FMs and building owners since 2005.

Keeping the joints sound
To get the most from the new sealant:
- Prioritise elevations facing the weather
- Log resealing dates block by block
- List the paperwork your organisation requires when you send details
- Make mastic part of routine maintenance checks
Keep bins, bikes and deliveries away from low-level joints where you can. Knocks cause many early failures in communal areas.
The longer failed joints are left, the more likely the substrate edges break up. Then the edges may need repairing first and the job grows.
How the quote is worked out
These are the things that shape the price:
- How accessible the joints are
- Joint width, depth and condition
- Which sealant the job calls for
- How much there is to seal
No two sites price the same: joint size, product, access and site hours all play a part. Send the details and a fixed figure follows.
What to include in your enquiry
A few photos plus some basic facts will normally do. It helps to include:
- Access details, including height
- Any specification or named product
- Where the site is, with the postcode
- Drawings or a marked-up plan, if available
For a fixed quote, call the office on 01277 525 020 or email us with the site address and an outline of the work. Our quote form is another easy route.
Frames, entrances and external joints in Dean Court
The South East is one of the drier parts of the UK. Outside work still depends on dry joints, and elevations facing the sun and the prevailing weather are typically where frame mastic ages first.

FAQs: Dean Court

Do you work with property factors and landlords?

How do you choose the sealant?
If the job is specified, we follow the specification. If not, we choose for the movement, the surfaces and the conditions, in line with the manufacturer’s guidance.
Will residents or tenants be disturbed?
Occupiers stay in the building throughout. If any flats or units need access, we’ll tell you in advance so it can be arranged.

Do you guarantee the mastic work?
Every building we reseal has a 12-month guarantee. It applies to our workmanship rather than damage or problems with the frames.
What the job involves on each surface
External movement joints
External movement joints take up expansion and contraction. Failed sealant in a movement joint lets water in.
Window and door perimeters on blocks
Blocks have a mix of frame materials, so the grade we pick has to bond to frame and wall alike. We’ll confirm the colours available for the specified product.
Other services in Dean Court
Work for main contractors and building owners
We work for building owners and managing agents on sealant work across single buildings or whole portfolios around Dean Court. Several sites can go on one quote, so there’s one set of paperwork to deal with.
Facilities managers want contractors who arrive with the paperwork sorted. Tell us what site paperwork you need, such as RAMS, an insurance certificate or CSCS details, and we will confirm with the quote.
Signs you need mastic sealing in Dean Court
We often find joints filled solid with no backing rod, so the mastic is glued to the joint bottom too. That three-sided adhesion stops it stretching and splits as the building moves.
Site and facilities staff are often the first to spot these:
- Brittle perimeter mastic across a building
- A mix of products and colours from past repairs
- No planned programme for sealant
- Estate-wide sealant that is simply worn out
Owners of student blocks near Azad University in Oxford (to the north-west of Dean Court) can schedule frame and external mastic for the summer vacation.
What to look for in a quote
- Which product they’ll use, and why it suits the joint
- Do they follow the manufacturer’s priming guidance?
- Health and safety accreditation such as CHAS
- Whether their applicators hold CSCS cards
