Construction mastic for businesses in Knightwood
Share the site address and what’s failing, and we’ll reply with a fixed quote or arrange a visit.
Why deal with it now?
Some packages split mastic across the window fitter, kitchen fitter and plumber. In practice it often means different standards, gaps in responsibility and snags nobody owns. One mastic subcontractor for the lot keeps it simple. In a smaller place such as Knightwood, 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.
Small jobs and large programmes are priced from the same things: scope, access, product and programme. Call for a quote and we’ll put a fixed figure on it.

How we handle construction mastic in Knightwood
Site managers want applicators who turn up with the right cards and paperwork. Our applicators are CSCS-carded, and we’re CHAS accredited and a Constructionline member, and we are fully insured. Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we will confirm with the quote. We work on window and door perimeters, brick and block movement joints and cladding and panel joints, and the usual reasons a site gets in touch are bath and shower joints scraped during the final clean and mastic snags holding up handover. Looking for mastic applicators who cover Knightwood? Mastic Doctor has worked for contractors, FMs and building owners since 2005, with CSCS-carded applicators.
Around places like Knightwood, a lot of construction is the conversion of older buildings, and the sealant at those junctions has to cope with two materials that move differently.
Every job we finish is backed by a 12-month workmanship guarantee. If our installation lets you down in that time, we return and fix it.

Work for main contractors and building owners

When you manage a building on behalf of an owner, you need clear quotes and clear reporting. You get a fixed quote, an agreed scope and a walk round at the end, plus a 12-month guarantee.
When something else is needed
A proper diagnosis includes knowing what sealant can’t do. We will tell you if the real problem is any of the following:
- Fire-stopping design or sign-off (that’s for the designer, fire engineer and building control)
- Oversized gaps that need packing or adjustment by others
- Joint design decisions that belong to the architect or engineer
Not sure which it is? You can call the office on 01277 525 020 or use the quote form and we’ll tell you honestly.

Knightwood: questions and answers
Do you take on work at healthcare sites like Wessex Hospital?
Yes. Healthcare sites are among the places we work. Each area is agreed with the ward or department and the estates team in advance.
Can you work at a site such as Monks Brook Industrial Park, by Knightwood?
Yes. Our area takes in Knightwood and its surroundings, with estates and business parks such as Monks Brook Industrial Park included. To start, just give us a call on 01277 525 020 or send photos by email with the unit, the joints involved and your access times.
Can you come in just for snagging?
Yes. Share the list and photos, and a fixed quote follows.
Can you quote from photos?
That depends on the size and complexity of the job. Straightforward work can often be priced from photographs and measurements, and bigger or more complex jobs normally get a visit.
What about RAMS and site documents?
Requirements differ from site to site, so list what you need, whether RAMS, insurance or CSCS details, and we will confirm with the quote.
How do you deal with asbestos in old sealant?
The duty to manage asbestos sits with the building’s dutyholder, so for older buildings we ask for the asbestos register first. Work pauses if suspect material is found, until it has been tested.
Can you handle several sites?
Yes. We take on portfolio and planned maintenance work, with each site phased to suit its occupants.

What else we do in Knightwood
What sets the cost
What shapes the price:
- Which sealant the job calls for
- Quantities, in metres or numbers
- Induction, permit and paperwork requirements
- Removal of failed or old sealant
Every site prices differently: joint size, product, access and site hours all play a part. A fixed quote follows once we understand the job.
Sending details for a quote
The more we know, the firmer the quote. Helpful details to send:
- A wide shot and a close-up of the area
- Whether an asbestos survey exists
- The postcode of the building
- The type of building and who uses it
For a fixed quote, give us a call on 01277 525 020 or email a schedule or drawings with the site address and an outline of the work. You can also send details through our quote form.
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.
For most general trades, sealant is a sideline. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint, which is what makes a joint last.
From enquiry to sign-off
Our CSCS-carded applicators arrive with the sealants, primers and backing rod the job calls for. Joint faces are cleaned back to sound, dry surfaces, the manufacturer’s primer is applied where it’s called for, and each bead is tooled to a neat concave finish. For a job in Knightwood, the main thing is a clear picture of the work, so send photos of each area. A fixed quote follows.
- We walk the site or review drawings to understand the package.
- You receive a fixed quote covering scope, products and sequence.
- Site paperwork is confirmed and our CSCS-carded applicators are inducted.
- We seal plot by plot or floor by floor in line with the programme.
- Problems we find, such as oversized gaps, are raised right away.
- The package is closed out, snags cleared and backed by our 12-month guarantee.
What we need from you
- Tell us which areas need to stay in use
- Move anything stored against the joints
- Send any specification or drawings in advance
