How we handle construction mastic in Widmore
Since 2005 we’ve worked alongside main contractors, developers and fit-out firms. We price from drawings and the specification, agree the sequence with the site team and seal as areas are released. For construction mastic on a scheme in Widmore, send drawings through our quote form, or phone or email us to talk it through. We work on sanitary and kitchen joints, brick and block movement joints and window and door perimeters, and the usual reasons a site gets in touch are snag items on joints that need redoing before handover and sanitary sealant damaged by following trades. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, the work in Widmore is the same: the right product in a properly prepared joint.
The ULEZ covers the whole of Greater London, so contractors’ vehicles on a job in Widmore must meet its standards or pay the daily charge. Alongside that, sites typically need booked deliveries and a plan for where materials go.
The 12-month guarantee is for workmanship rather than wear and tear. How long a sealant joint lasts depends on movement, exposure, cleaning and use, so we spell out the cover before we begin.

Diagnose, treat, 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, primer goes on where the manufacturer specifies it, and each bead is tooled to a neat concave finish. All of Greater London is in the ULEZ, and kerbside space in Widmore can be scarce. If there’s a loading bay, a car park or a permit we can use, tell us when you send details.
- We walk the site or review drawings to understand the package.
- You receive a fixed quote covering scope, products and sequence.
- Paperwork is agreed and applicators are inducted on site.
- Sealing follows the programme as areas are released.
- Any frame gaps or issues outside our scope are flagged to the site team.
- The package is closed out, snags cleared and backed by our 12-month guarantee.
Getting the site ready
- Flag any permit to work we’ll need
- Agree which areas must stay open
- Clear stock, furniture or equipment away from the joints
Getting a fixed quote
Every quote starts with the facts: what’s there, how much of it, how we reach it and what’s specified. Send what you have, and we will arrange a site visit if anything is unclear.
Advice
After the work
For the best life from the joints:
- Don’t force external sealing on a damp or frosty day
- Keep finished joints away from paint, plaster and scrapers
- Stick to the specified sealant rather than a generic substitute
- Don’t schedule sealing before decorators and flooring are done
At handover, keep the product details with the O&M information. Future maintenance is easier when the products are known and avoids guesswork when joints are renewed. Tell us what records you need and we’ll confirm with the quote.
One unsealed frame can let water into finished internal areas. On a new building that means remedial work after decorating and possibly a delayed handover. Checking perimeters before internal finishes go on avoids it.
Surface by surface
External facade and movement joints
Movement joints in the facade are sealed with a product suited to the expected movement. We set the depth with backing rod to avoid three-sided adhesion.
Snagging before handover
Damaged, missed or untidy joints make up most snag lists. Snagging can be included or priced separately.
Doing it in-house
For most general trades, sealant is a sideline. A specialist prepares properly, controls joint depth and picks a product with the right movement class.
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.
What affects the price in Widmore
We price every job individually. The main factors are:
- How much existing material needs removing
- Phasing around occupants
- Any access equipment needed
- Induction, permit and paperwork requirements
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 you will have a fixed figure to work with.
What we need to price the job
We can often quote from photographs and a few details. Please tell us:
- Photos of the joints, close up and from further back
- The type of building and who uses it
- Specification clauses that apply
- Drawings or a marked-up plan, if available
The quickest route to a quote is a few photographs and the site postcode. Send them through the quote form, or ring 01277 525 020 or email drawings and photos if you’d rather talk the job through.
Building and refurbishing in Widmore
Site traffic in Widmore falls within London’s ULEZ, like everywhere else in Greater London. Delivery slots and scarce storage shape how and when the mastic goes in. A number of hotels sit less than 2 miles from Widmore. Hotel refurbishments often run to tight programmes between busy periods, and perimeter and sanitary sealant has to keep up.
Further education sites such as Bromley College (to the south-west of Widmore) are extended and refurbished from time to time, with mastic often programmed into the summer break. For contractors on a campus like University of Greenwich - Avery Hill, 3.4 miles to the north of Widmore, facade and perimeter sealing has to fit around students and term dates. Work at a hotel such as Bickley Manor Hotel and Restaurant (to the south-east of Widmore) tends to be programmed around bookings, mastic included.

Your questions answered
Can you cope with the access rules in a London building?
Yes. Inductions, permits and timed loading are routine for us in London. Say when the building is occupied and when it’s quiet, and we will plan accordingly. We allow for the ULEZ, which covers every borough
Can you work at a site such as Chartwell Business Centre, by Widmore?
Yes, sites like Chartwell Business Centre are within our area, along with the rest of Widmore. Photos and a short description are enough for a first look.
Do your applicators hold CSCS cards?
We are CHAS accredited and a Constructionline member, with CSCS-carded applicators. We are also fully insured, with five million pounds of public liability cover.
Can you fit around our programme?
We work to your programme. Tell us the sequence and we’ll plan applicators around it so sealing follows the trades.
Do you need to see the site first?
It depends on the job. Straightforward work can often be priced from photos and measurements, and bigger or more complex jobs normally get a visit.
Can you work to our specification?
We follow the specified sealant, and we’ll raise it if something in it doesn’t suit the joint. Specifications often reference BS EN 15651 or BS 6213.
How long before the joints can be used?
That comes down to the sealant and the temperature. Some take light use quickly, others need longer to cure, so we’ll confirm the curing time on the day.

When something else is needed
A few problems need another trade or a different fix, and we point that out rather than sealing over them:
- Oversized gaps that need packing or adjustment by others
- Glazing units that are cracked or misted
- Rework caused by others damaging completed areas
If you are not sure, just give us a call on 01277 525 020 or email drawings and photos and we will give you a straight answer.
