What sealant work can’t fix

- Leaks through the frame itself rather than the perimeter
- Water coming in from the roof or rainwater goods

How we handle mastic sealing in Northfield
There isn’t one mastic for every joint on a building. Window perimeters and external joints often take a low-modulus neutral-cure silicone, and MS polymer sealants stick well to many substrates and often take paint, and colours are confirmed for whichever product is used. The enquiries we see most involve water getting in round frames after rain and a mix of products and colours from past repairs, across communal kitchens and washrooms, communal entrances and stairwells and balcony and threshold joints. Looking for mastic applicators who cover Northfield? Mastic Doctor has worked for contractors, FMs and building owners since 2005, CHAS accredited and a Constructionline member.
Tenements are a large part of the housing in Scotland’s cities, and shared repairs often go through a property factor. Shared-part mastic work is normally agreed by the owners, often through the factor, and can cover a whole close or block.
We sign every job off with a 12-month guarantee. The promise is simple: if our work fails within that year, we put it right.

Why deal with it now?

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’ll put a fixed figure on it.

FAQs: Northfield
Do you work for managing agents with blocks near Aberdeen station?
Yes, we work for agents, landlords and housing associations with blocks of every size. Photos of each elevation help us quote accurately.
Who arranges mastic work on a tenement in Northfield?
Typically through the property factor, once the owners have agreed. We’re happy to deal with the factor directly.
What guarantee do you give on resealing?
Every building we reseal has a 12-month guarantee. It applies to our workmanship rather than damage or problems with the frames.
Is it fine to apply new sealant on top of old?
No. Overlaying old sealant is a frequent cause of early failure, so everything comes out first.
How long does a job like this take?
The duration is planned around your programme and the access we are given. We’ll give you an estimate of time on site when we quote.
How long before the joints can be used?
That comes down to the sealant and the temperature. Some products skin over quickly but need longer to cure fully, and we confirm it before leaving site.
Do you cover Northfield?
Yes. We cover Northfield, and you can call 01277 525 020 or email us to get started.
Owners, agents and contractors
Hotels, schools, healthcare sites, offices and retail units book us directly too. The work is planned around how the building runs, so the building keeps working while we do.
Whether you are a managing agent, a property factor or an owner’s representative: send the details, accept a fixed quote, and we carry out and guarantee the work. We can agree access arrangements and keyholder contacts beforehand.

When to call us in Northfield
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.
Clients normally get in touch after noticing something like this:
- Occupiers reporting cold air round windows
- Communal area joints that look neglected
- Leaks at window and door perimeters

- Will CSCS-carded applicators be on site?
Different surfaces, different methods
Window and door perimeters on blocks
Frames vary from uPVC to aluminium and timber, so the grade we pick has to bond to frame and wall alike. We’ll confirm the colours available for the specified product.
Planned maintenance
How long mastic lasts depends on exposure, movement and the product used. Inspecting joints regularly keeps programmes on track.
