Quoting for work in Goddington
Quotes vary with the job. Expect it to depend on:
- Whether old sealant has to be cut out first
- Phasing around occupants
- Quantities, in metres or numbers
- Joint width, depth and condition
The product called for affects the cost, and so does the preparation. Access, phasing and site rules also count.
What we need to price the job
To price the job accurately, we need to understand the site. Useful things to include:
- Drawings or a marked-up plan, if available
- The product your specification calls for
- The type of building and who uses it
- The asbestos register, for older buildings
A handful of photographs and a postcode is the fastest way to a quote. Upload them with the quote form, or give us a call on 01277 525 020 or email the details over to discuss it first.
Construction mastic for commercial buildings in Goddington
The specification and the programme set the job. If a product is named, that’s what goes in; any alternative we suggest is put to you before anything changes. Joint widths, backing, primers and tooling follow the manufacturer’s guidance so the detail on the drawing is what ends up on site. We work on cladding and panel joints, window and door perimeters and floor and skirting junctions, and what we’re called in for most is mastic snags holding up handover and sanitary sealant damaged by following trades. For commercial sealant work in Goddington, you deal with one contact from quote to sign-off, whether it’s one building or several.
Building sites in London tend to be tight: limited storage, booked deliveries and access shared with other trades. Mastic is normally one of the last trades on each elevation or floor, so we keep to the programme and the order of trades the site sets.
Whoever the client is, the cover is the same: a 12-month guarantee on our workmanship. Faults in the structure, damage and other trades’ work fall outside it, and we say so plainly.

Construction mastic around Goddington: how the place shapes the job
The ULEZ covers the whole of Greater London, Goddington included, so site vehicles need to meet its standards or pay the daily charge. London sites also mean booked deliveries and limited storage, which the mastic programme has to allow for. A 2-mile radius around Goddington takes in several hotels. Hotel extensions and refits usually have to fit around bookings, so mastic dates are tight.
Projects at schools like The Highway Primary School work to term dates, so mastic is programmed tightly. Goddington is inside London’s ULEZ, as is the rest of Greater London; tell us about loading bays, goods lifts and parking when you send details.
Goddington is about 1 mile south of Orpington, in Greater London. Across the BR6 postcode area, the process is the same: details in, fixed quote out, then sealing and a 12-month guarantee. Across Greater London, 764 places are covered, including Goddington. London is covered too, around 13 miles from Goddington.
Commercial sites across BR6 and BR5 are covered. If your site is on Eton Road, Stowe Road and Court Road or close by, send details and we will quote for mastic packages.

When to call us in Goddington
On construction sites, joints usually fail early because of when they were sealed, not what was used. If sealant goes in before the last trades are through, it gets knocked, painted over or contaminated, and the joint has to be redone.
Most enquiries start with one or more of the following:
- Different trades sealing to different standards
- Sanitary sealant damaged by following trades
- Failed sealant in an existing building being refurbished
- Snag items on joints that need redoing before handover
Recladding or extending a unit at a site like Halo Business Park, 1.8 miles to the north of Goddington, brings panel joints and frame perimeters into the programme.
Questions to ask before you book
- Is the sealant right for the movement and the substrate?
- Their public liability cover
- How the joint faces will be prepared and primed
- What the guarantee covers, and for how long
Keeping the joints sound
Your facilities or cleaning team can help the joints last. Pass these on to them:
- Use the product the specification names
- Plan external elevations with the weather in mind
- Check frame gaps are within the sealant’s range before sealing
- Don’t schedule sealing before decorators and flooring are done
After we’ve sealed an area, it helps to keep other trades from damaging the joints. Fresh sealant needs its cure time before it’s cleaned, painted near or knocked; we confirm the time for each product.
Oversized gaps are a problem better caught early. Sealant stretched over an oversized gap won’t last so packing or adjustment by the installer comes first. We raise them during our first walk of the area.
Different surfaces, different methods
External facade and movement joints
Brickwork, blockwork and panel movement joints need a sealant with the right movement capability. We set the depth with backing rod to avoid three-sided adhesion.
Snagging before handover
Snags normally come from damage by following trades, missed joints or poor earlier work. Snagging can be included or priced separately.
When something else is needed
Sealant solves a lot, but not everything, and we are upfront when that’s the case. It won’t fix:
- Specifying the product where the designer hasn’t
- Approving fire stopping as compliant
- Rework caused by others damaging completed areas
Not sure which it is? You can call the office on 01277 525 020 or send details through our quote form and we’ll tell you honestly.
Surfaces we seal
- Floor and skirting junctions
- Sanitary and kitchen joints
- Brick and block movement joints
- Window and door perimeters
- Cladding and panel joints
- Internal decorators’ caulk
On site: what to expect
When we get to site, we report to your site contact and complete whatever induction the building runs. Floors, finishes and fittings next to the joints are covered before anything is cut or cleaned, and the work normally takes whatever the programme allows, since the work follows the trades as areas are released. Planning a London job such as one in Goddington starts with access. Give us the hours we can be on site and we will schedule to suit.
- Drawings, specification and programme come to us.
- Quantities are measured and a fixed price returned.
- We agree with the site team which areas come first.
- Plots or floors are sealed as they’re handed over.
- Joints are prepared, backed and sealed to the specification.
- Snags are cleared and the package signed off with our 12-month guarantee.
What we need from you
- Send any specification or drawings in advance
- Flag any permit to work we’ll need
- Clear stock, furniture or equipment away from the joints
Getting a fixed quote
Photos, drawings or a schedule of the joints are often enough for a fixed quote. Where a site visit makes more sense, we’ll arrange one.
Related advice
Goddington: questions and answers
Is hospital work, at somewhere like Orpington Hospital, something you do?
Yes, provided the work is planned with the site’s estates team. Work is phased so departments keep running, under the site’s own rules.
Does your area include sites such as Halo Business Park, near Goddington?
Yes. Our area takes in Goddington and its surroundings, with estates and business parks such as Halo Business Park included. Photos and a short description are enough for a first look.
Will you just go over the old sealant?
No. We cut the old material out and clean the joint back before sealing, since fresh sealant will not bond reliably to aged material.
Do you do fire-rated sealing on new builds?
Where the specification calls for fire-rated or intumescent sealant around service penetrations or linear gaps, we install it to the manufacturer’s tested details. The design and sign-off belong to the designer, fire engineer or building control.
Can staff carry on working while you’re here?
Yes, with some planning. Tell us your site hours and access windows and we’ll plan around them.
Do you have public liability insurance?
Yes. We are fully insured, and the certificate can go with your quote.
Can one quote cover more than one building?
Yes. A group of buildings can go on one quote, and you deal with one contact throughout.
