About our commercial sealant contractors in Grahame Park
Having a single contact for all your sites makes sealant far simpler to manage. We take on one-off reseals, runs of jobs across a portfolio and planned maintenance programmes: send details, get a fixed quote, we seal, and a 12-month guarantee once it’s signed off. To get a programme moving in Grahame Park, speak to us on 01277 525 020 or send photos by email with the site addresses. Site teams most often ask us about movement joints packed with grit and debris and hardened, chalky sealant on south-facing or exposed elevations, on movement joints in walls and floors, washrooms and tea points and kitchen worktops and splashbacks. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, in Grahame Park it comes down to the same thing: failed joints cut out, faces prepared and the right sealant laid to the right depth.
In Grahame Park, as anywhere, the first joints to go are usually the ones that work hardest: frame perimeters in the sun, floor joints at doorways and anything that gets wet every day.
Around Grahame Park, as across the capital, commercial buildings range from converted period premises to recent office and mixed-use blocks, which means one visit can cover joints against stone, brickwork, coated aluminium and shop-fit panels. Each surface gets its own preparation and, where it’s seen, a sealant colour that sits with it.
Our workmanship is guaranteed for 12 months. If a joint we sealed fails because of how it was installed, we come back and put it right.

What sealant work can’t fix
A proper diagnosis includes knowing what sealant can’t do. You will hear from us if the cause turns out to be any of the following:
- Structural cracks or movement the joints weren’t designed for
- Faulty windows rather than failed perimeter sealant
- Leaks from pipework, wastes or valves (that’s plumbing)
Not sure which it is? You can give us a call on 01277 525 020 or send details through our quote form and we will tell you honestly.

How a job runs
On arrival, we sign in, go through any site induction and check how permits are handled. Everything around the joints gets protected before anything is cut or cleaned, and the work normally takes anything from part of a day on a short run of joints to several weeks on a large phased package. In Grahame Park, most buildings stay in use during the work, so zones and timings are agreed with whoever manages the building. Areas are handed back as each section is finished.
- First, details reach us through the quote form or a site visit.
- The cause is diagnosed and the scope priced as a fixed quote.
- Work is phased around your occupiers where areas need to stay in use.
- Every failed bead is removed rather than covered.
- A suitable product for each joint goes in at the right depth and is tooled.
- We check the work with you, and the 12-month guarantee starts.
Getting the site ready
- Tell staff and tenants when we will be in
- For older buildings, check the asbestos register before work
- Send any specification or drawings in advance

Different surfaces, different methods
Fire-rated seals where specified
Intumescent and other fire-rated sealants go in at service penetrations and linear gaps to the maker’s tested details, where they are specified. The design and sign-off of fire stopping belong to the designer and building control, and we install to the specification.
Window and door perimeters
Internally, window boards and frame edges often have decorators’ caulk or silicone that has cracked. We use a paintable product where decorating follows and a silicone where it doesn’t, matched to the frame colour where colour matters.
What sets the cost
A fixed quote reflects the actual work. It allows for:
- Whether old sealant has to be cut out first
- The total length or number of joints
- Induction, permit and paperwork requirements
- Whether the work must be split into stages
The work involved drives the cost: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a fixed quote.
What to include in your enquiry
However big the job, the same details help:
- Clear photographs of the problem areas
- Approximate linear metres or a joint schedule
- Asbestos survey details if the building is older
- Whether the building will be occupied during the work

Site staff or a sealant specialist?
There’s also the paperwork. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and we will confirm the paperwork you need with the quote.
Site maintenance staff can often handle a short internal joint. The usual problems come from preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.
Shops, offices and hotels in and around Grahame Park
Most London commercial buildings run contractors through a reception, a permit system and booked goods-lift slots. We plan around them and agree phasing so tenants and customers aren’t disrupted. A good number of hotels sit less than 2 miles from Grahame Park. Refits in hotels bring joints at vanity tops, bar counters and reception desks where the colour has to suit the scheme.
Shops and cafés around stations like Mill Hill Broadway station (to the north of Grahame Park) trade from early, so work is timed around them. For a hotel such as Hendon Hall Hotel, which lies east of Grahame Park, the colour of a joint at the bar or the bath matters to the look of the room. With Grahame Park inside the ULEZ and kerb space scarce, we sort access and loading before the first day on site.

Questions we’re asked in Grahame Park
Do hotels near Grahame Park have to close for sealant work?
Rarely, if ever. We take a few rooms out at a time. Tell us your quiet periods and access windows and we will plan around them.
Can you work in a London building with booked loading and goods-lift slots?
Yes. Booked loading bays, goods lifts and permit-to-work systems are normal for London jobs. The building manager’s rules go straight into our method. All of Greater London is inside the ULEZ, and our planning allows for it
How long do sealant joints last?
There’s no fixed lifespan: movement, exposure, cleaning, traffic and the product all play a part. Sealant joints are maintenance items, so inspect them regularly.
Is the old sealant taken out first?
Every failed bead is cut out completely. Laying new silicone on old gives it nothing to grip, and the faces are brought back to sound, dry material before resealing.
Is your work guaranteed?
Our workmanship on each job is backed by a 12-month guarantee. We are fully insured for public liability as well.
Can you work to our specification?
Yes. The specification and the manufacturer’s installation guidance are what we work to, and any queries are raised before we start.
Do you cover Grahame Park?
Yes. We cover Grahame Park, within our coverage of Greater London, South East England and Scotland. For a quote, ring 01277 525 020 or email the details over.
Keeping the joints sound
Once the work is signed off, these steps help:
- Make sure contractors see the asbestos survey before cutting out old mastic
- Keep a record of which joints were resealed and when
- Look at the sealant around anything that has been moved or replaced
- Put external and wet-area joints on a regular inspection round
Give fresh sealant time to cure before it’s cleaned, wetted or walked past. That time depends on the product, the temperature and the joint depth. Keeping signs or barriers up until then protects the finish.
Each spell of wet weather pushes more water through an open joint. It can run into cavities, insulation and internal finishes long before anyone sees a stain. Resealing early keeps the problem in the sealant and out of the building.
