Mastic sealing in Gurnard, done properly
Before work starts, most agents and landlords want the documents in order. Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we will confirm with the quote. We are a Constructionline member and CHAS accredited, and we carry public liability insurance. We work on communal kitchens and washrooms, external wall and movement joints and balcony and threshold joints, and what we’re called in for most is worn sealant at communal door frames and damp patches beside frames. Looking for mastic applicators who cover Gurnard? Mastic Doctor has worked for contractors, FMs and building owners since 2005.
For owners with a single building near Gurnard, we plan to finish in one visit where possible. Photos of each elevation help us quote accurately.
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 are upfront about that.

When it isn’t the sealant
A few problems need another trade or a different fix, and we say so rather than covering them up:
- Glazing that needs replacing
- Substrate edges that need repairing first
- Leaks through the frame itself rather than the perimeter
If in doubt, give us a call on 01277 525 020 or email us and we’ll say what we think.
Surfaces we seal
- External wall and movement joints
- Shopfronts below residential blocks

- Balcony and threshold joints
Why act early in Gurnard
Sealing over failed mastic looks tidy for a while. It doesn’t bond and usually fails within a short time. Full removal and proper preparation is what lasts. Around Gurnard, it’s better to renew all the failing joints at once, rather than one at a time. Send photographs of each area and we will quote for the lot.
No two sites price the same: the joint sizes, the specified product, access and working hours each have a bearing. Send the details and a fixed figure follows.
What you get with us
- Work to your specification and the manufacturer’s guidance
- Failed material removed, not covered up
- Fully insured
- 12 months’ guarantee on every job

What the job involves on each surface
Tenement and older buildings
Older buildings, including Scotland’s sandstone tenements, have their own joint details. The material either side of the joint shapes the product choice.
Communal areas
We keep entrances and stairs open throughout. We work in sections so access is never blocked.
Our process
A typical day starts with protection: masking tape along the joint edges and sheeting over anything nearby. On site, the work usually takes anything from a day to a few weeks, depending on the number of buildings and joints, and our waste is bagged and taken away as we go. For work around Gurnard, we aim to finish in one visit, so we ask for photos and rough sizes first. That way the right products come on the day.
- First comes a look at the joints and, for older buildings, the asbestos records.
- A fixed quote covers the joints, products and order of work.
- Failed mastic is removed completely.
- Joint faces are cleaned, backed and resealed.
- We finish each building before moving to the next.
Getting the site ready
- Send your site hours and access windows
- Confirm the product named in the specification
- Tell us which areas need to stay in use

Advice
Your questions answered
Is a smaller place like Gurnard outside your area?
Not at all: smaller places are covered as well as towns. We cover Greater London and the counties of the South East. Where we can, we group nearby jobs to make the most of each trip.
Does the sea air around Gurnard change the choice of sealant?
It can. Coastal exposure works external joints harder than inland weather. We check the specified product suits the exposure and pay close attention to preparation.
How do you handle work on occupied blocks?
The work is planned around occupiers. We agree the programme so you can notify occupiers, and entrances stay in use.
Do you work with property factors and landlords?
Yes, that’s exactly who this service is for. We work through buildings in a planned order so you can plan around it.
Do you guarantee the mastic work?
A 12-month guarantee covers our work. It covers our workmanship, not later building movement, damage or frame failures.
How long does a job like this take?
That varies with the scale of the job, though a typical visit normally takes anything from a day to a few weeks, depending on the number of buildings and joints. For bigger or phased jobs, we’ll set out a timescale with the quote.
What paperwork can you provide?
We are CHAS accredited, a Constructionline member and carry public liability insurance. Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we’ll confirm with the quote.

When to bring in a specialist
The visible bead is only part of the job. Correct depth, the right primer and a sealant matched to the movement are easy to get wrong without experience.
There’s also the paperwork. Many sites expect CSCS cards, RAMS and proof of insurance, and we will confirm the paperwork you need with the quote.
Do you need mastic sealing in Gurnard?
We often find joints filled solid with no backing rod so the mastic is bonded on three sides. That three-sided adhesion stops it stretching and it tears.
Common reasons buildings call us in:
- Water getting in round frames after rain
- Repeated reactive repairs to the same buildings
- Communal area joints that look neglected
- Draught complaints from residents or tenants
Older community buildings, All Saints' Church among them, often have frames of mixed ages whose mastic varies.
