How we handle construction mastic in Maida Vale
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 Maida Vale, send drawings through our quote form, or phone or email us to talk it through. We work on floor and skirting junctions, sanitary and kitchen joints and brick and block movement joints, and the usual reasons a site gets in touch are failed sealant in an existing building being refurbished and different trades sealing to different standards. A specialist sealant contractor works differently from a general builder: on jobs in Maida Vale, preparation and product choice get the time they need.
Construction in a London area such as Maida Vale means working on constrained sites: 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.
What our 12-month guarantee covers is the way we did the job: the preparation, the sealing and the tooling. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

Owners, agents and contractors
For main contractors, we work as the sealant subcontractor on new-build and refurbishment projects. Programme, specification and site rules come first, with CSCS-carded applicators on site.
Agents, factors and owners’ representatives all follow the same route: send details, get a fixed quote, we seal, guaranteed. Keys, access and contacts can be agreed in advance.
When it isn’t the sealant
Our job is the joint, not everything around it. Sealant alone won’t deal with:
- Joints damaged after sign-off by following trades
- Defective windows, doors or glazing units (the supplier or installer’s job)
- Oversized gaps that need packing or adjustment by others
If you’re not sure, just ring 01277 525 020 or email us and we’ll give you a straight answer.
Where we work in Maida Vale

On site: what to expect
We schedule the visit to fit the site hours and access windows you give us. While we’re working, the area stays contained and tidy, and we check in with your contact before moving on to each new area. Most London premises stay occupied while we are on site, so zones and timings are agreed with whoever manages the building. Areas are handed back as each section is finished.
- 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.
- Each area is sealed when it’s released.
- Every joint is cleaned, set to depth and sealed with the specified product.
- Snags are cleared and the package signed off with our 12-month guarantee.
Getting the site ready
- Let us know about inductions and permits
- Explain the parking and delivery arrangements
- Have the specification and drawings to hand

Related advice
What we’re called out for in Maida Vale
Three-sided adhesion is a frequent fault on new work. Fixed to three faces, the sealant rips the first time the joint opens so we set the depth properly before sealing.
Clients typically get in touch after noticing something like this:
- Old sealant on a refurbishment that needs stripping before new work
- Perimeter gaps outside the sealant’s range
- A mastic package split between trades with no clear owner
- Caulk cracking where joints are moving more than expected
Further education sites such as City of Westminster College, less than half a mile west of Maida Vale, are extended and refurbished from time to time, with mastic often programmed into the summer break.
Questions to ask before you book
- Whether old or failed sealant will be cut out, not overlaid
- Their approach to joint depth and backing
- Will RAMS and insurance details be available?
- Will CSCS-carded applicators be on site?
New build and refits around Maida Vale
The ULEZ covers the whole of Greater London, Maida Vale included, so site vehicles need to meet its standards or pay the daily charge. Delivery slots and scarce storage shape how and when the mastic goes in. A 2-mile radius around Maida Vale takes in plenty of hotels. Hotel refurbishments often run to tight programmes between busy periods, and perimeter and sanitary sealant has to keep up.
On a campus such as Imperial College London, 1 mile south-east of Maida Vale, new teaching buildings and residences are normally built and refurbished around the academic year. New wings at hospitals like Hospital of St John and St Elizabeth, 0.8 miles to the north-east of Maida Vale, bring long runs of window and panel joints to seal.

Maintenance after handover
Cleaning and maintenance staff play a part too. Share these points with them:
- Brief the final clean team to avoid blades near sealant
- Note which sealant went where at handover
- Check frame gaps are within the sealant’s range before sealing
- Stick to the specified sealant rather than a generic substitute
Record which products went where in the handover file. Future maintenance is easier when the products are known and avoids guesswork when joints are renewed. We can confirm the handover information you need when we quote.
In wet areas, a weak sanitary joint shows up quickly once the building is occupied. Water gets behind trays, vanity tops and panels. Proper preparation, with the right silicone first time, keeps it off the defects list.
Leave it or put it right?
A cheaper sealant can look like an easy saving on a large package. A failed joint in the defects period costs far more than the product difference and external joints are where it shows first. Where an alternative is genuinely suitable, we’ll say so. In Maida Vale, each extra visit means more notices, permits and disruption, so cutting the old sealant out fully and doing it right once is the better route.
Every site prices differently: the joint sizes, the specified product, access and working hours each have a bearing. A fixed quote follows once we understand the job.
Why us?
- Workmanship guaranteed for 12 months
- Public liability insurance in place
- Fixed quotes based on photographs, drawings or a visit
- Joints cleaned back to sound surfaces

Your questions answered
Does your area include sites such as The Quadrant Business Centre, near Maida Vale?
Yes. Estates, retail parks and business parks around Maida Vale, The Quadrant Business Centre among them, are all within reach. Photos and a short description are enough for a first look.
Will you plan work around the academic year at somewhere like Imperial College London?
Yes. Tell us the term dates, vacation periods and access windows, and we’ll plan the work around them. Tell us which site documents you need, such as RAMS, our insurance certificate or CSCS details, and they’re confirmed with the quote.
How do you work with the site programme?
Our work is sequenced around the programme. Areas are sealed as they’re released by the site team and we tell you if something stops an area being sealed.
Are you CHAS accredited?
We are CHAS accredited and a Constructionline member, and our applicators hold CSCS cards. Tell us what site paperwork you need and we will confirm with the quote.
Which sealant will you use?
The specification comes first, if there is one. If there isn’t one, it comes down to the joint: its movement, its surfaces and what it has to cope with.
What do you charge?
Each job is quoted on its own details. For yours, phone 01277 525 020 or send details through our quote form.
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. Fire-stopping design and sign-off sit with the designer and building control.
