About our facade sealing in Askett
Most facade joint failures trace back to the joint, not just the sealant. Joint width needs to match how far the joint moves and how far the sealant can stretch, and closed-cell rod sets the depth, keeping the bond to two faces with the ratio the sealant maker recommends, often around 2:1. We work on shopfront frames, window and door perimeters and stone and brick facade joints, and the usual reasons a site gets in touch are gaps between rainscreen or cladding panels and weathered facade joints that have lost their grip. Searching for sealant specialists in Askett? Mastic Doctor has worked for contractors, FMs and building owners since 2005, with CSCS-carded applicators.
For a site near Askett, the mastic visit is planned so the right sealants, primers and backing rod are on hand. Drawings, photographs and the programme let us give a fixed quote.
Every job we finish is backed by a 12-month workmanship guarantee, wherever the site is. If a joint we sealed fails because of how it was installed, we come back and put it right.

What affects the price in Askett
Before we quote, we look at:
- Distance, for remote addresses
- Induction, permit and paperwork requirements
- Access and working height
- Quantities, in metres or numbers
Access can matter as much as the joints themselves: easy-to-reach joints are quicker than those that need equipment to get to. Mention the access as part of your enquiry.
Sending details for a quote
To price the job accurately, we need to understand the site. Useful things to include:
- Rough lengths or quantities, or drawings if you have them
- How the joints are reached, and at what height
- Photos of the joints, close up and from further back
- Asbestos survey details if the building is older
Send details, get a quote, we seal, guaranteed: that’s how every job runs. To take the first step, phone 01277 525 020 or email drawings and photos.
General trades versus a specialist
Certain joints really need a specialist: for example fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. Getting these wrong usually costs more in the end than doing them right.
The visible bead is only part of the job. Correct depth, the right primer and a sealant matched to the movement are where general trades tend to cut corners.
From enquiry to sign-off
Before we leave any area, we remove the tape, clean down and inspect every joint, ready for your sign-off. If an area should be left alone while the sealant cures, we say how long and put signs out. If others near Askett need work, visits can be combined, which keeps travel down. A fixed quote is given before anything starts.
- We start with photographs, drawings or a visit to see the joints and agree access.
- Product choice follows the joint’s movement and substrate.
- Failed beads are removed in full and the joint faces cleaned.
- Primer is applied where the maker specifies it.
- Rod goes in to fix the depth, then the joint is sealed and tooled.
- The finished joints are checked with you.
Preparing the site
- Tell staff and tenants when we’ll be in
- Agree which areas must stay open
- Tell us your opening times and when work is allowed
Ask for a quote
We quote a fixed sum against the scope you give us, so you know the figure before anyone is on site. To ask for one, speak to us on 01277 525 020 or email a schedule or drawings.
Advice
What we are called out for in Askett
The wrong product causes its share of trouble: acetoxy-cure silicone may mark stone or corrode certain metals, and an interior product won’t last outdoors. Neutral-cure, facade-grade products are what most external joints need.
Site and facilities staff are often the first to spot these:
- Air leaks through failed facade joints
- Failed sealant on precast panel joints
- Discoloured or dirty facade joints
- Weathered joints at frame-to-structure perimeters
School extensions, at buildings such as Monks Risborough CofE Primary School, typically run to the summer holidays, mastic included.
What your quote should include
- Whether their applicators hold CSCS cards
- Their pre-qualification and accreditations
- How they’ll work around occupants
- Will failed sealant be removed rather than covered?

Aftercare for building managers
Your facilities or cleaning team can help the joints last. Pass these on to them:
- Keep sills, gutters and drainage paths clear
- Don’t wait for a second leak before calling
- Insist on a full cut-out when joints are renewed
- Plan facade sealing alongside redecoration
Hold back any cleaning crew until the joints have had their stated cure time. Keep high-pressure jets and strong chemicals away from new sealant, so brief your window cleaners.
In pre-2000 buildings, check the asbestos register before old sealant is cut out. Some older mastics contain it.
Your questions answered
Is a hospital such as The Paddocks Hospital somewhere you can work?
Yes, hospitals are one of the sectors we cover. Each area is agreed with the ward or department and the estates team in advance.
Is Askett off your patch?
Not at all: smaller places are covered as well as towns. We cover Greater London and the counties of the South East. We plan jobs in smaller places so return trips are kept to a minimum.
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 everything comes out first.
Will rain stop the work?
Year-round work is possible as long as joints are dry and temperatures suit the product. Cold, damp mornings can delay a start, and we build that into the programme.
Do you use silicone for external joints?
It depends on the joint, the substrate and any specification. BS EN 15651 Parts 1 and 2 cover facade and glazing sealants, and specifications often name them and we follow the specified product.
How many days will you need on site?
That varies with the scale of the job, but the work usually takes a day or two for a few elevations, and longer where access has to be moved around the building. For bigger or phased jobs, we will set out a timescale with the quote.
Will your applicators have CSCS cards?
Yes. Should the site need card details in advance, let us know and we’ll send them with the quote.
When something else is needed
Part of a good diagnosis is knowing where sealant stops. We’ll tell you if the real problem is one of these:
- Installing or repairing glazing systems
- Arranging specialist high-level access, which is planned with the client
- Damp caused by condensation inside the building
If in doubt, phone 01277 525 020 or email the details over and we will say what we think before you book.
Surfaces we seal
- Coping and flashing joints
- Shopfront frames
- Perimeter joints where frames meet the structure
- Window and door perimeters
- Stone and brick facade joints
- Cladding panel joints

Central London is about 35 miles from Askett. Towns within reach of London tend to keep building, from flats to offices and schools, which keeps mastic packages in demand.
