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, the manufacturer’s primer is applied where it’s called for, and the sealant is tooled off neatly. All of Greater London is in the ULEZ, and kerbside space in North Hyde 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 check the asbestos register for older buildings and look at the joints.
- A fixed quote covers the joints, products and order of work.
- We strip out the old sealant.
- Joint faces are cleaned, backed and resealed.
- We finish each building before moving to the next.

How we handle mastic sealing in North Hyde
For blocks and buildings in North Hyde and across Greater London, the process is the same: you send details, we return a fixed quote, the joints are resealed and the 12-month guarantee follows. A list of buildings, a few photographs and approximate joint numbers are enough for a quick quote, and site visits can be arranged. Site teams most often ask us about the same joint failures repeated across a portfolio and movement joints with sealant missing, on balcony and threshold joints, communal entrances and stairwells and window and door perimeters on blocks. One point of contact handles commercial sealant work in North Hyde from the first photos to the final walk-round, for single jobs and planned programmes alike.
Planning mastic work on a London block means notices to residents, access to flats and agreed working areas. Work is planned with the agent so residents get notice and access is arranged in advance.
We stand behind the joints we seal: 12 months, guaranteed. That covers our preparation and application, and we come back if anything isn’t right.

What else we do in North Hyde
Keeping the joints sound
Every sealant joint needs some looking after, and their life depends on movement, exposure, cleaning and use. Our advice:
- Protect low-level joints in entrances
- Make mastic part of routine maintenance checks
- Ask residents or tenants to report leaks and draughts early
- Share your contractor requirements early
If a joint we sealed fails within 12 months, tell us and we’ll look at it. After that, regular inspection keeps the programme on track.
Budgets are easier to plan when sealant is part of planned maintenance. We can quote buildings in priority order and work down the list.
Why act early in North Hyde
Looking at mastic during planned maintenance costs little. Waiting until leaks appear means working under pressure and less choice about when. Access in London is hard enough to arrange once, so it makes sense to deal with every failing joint while access is in place.
Pricing mastic joints depends on quantities, condition and access, and any specification that applies. Ask us for a fixed quote.
Why us?
- Old sealant cut out, never sealed over
- Products installed to the manufacturer’s instructions
- One contact handling all your sites
- A Constructionline member, so easy to vet

Work for main contractors and building owners
Hotels, schools, healthcare sites, offices and retail units book us directly too. The work is planned around how the building runs, so the building keeps working while we do.
Main contractors use us as their sealant subcontractor on new-build and refurbishment projects. We work to your programme, your specification and your site rules, and our applicators hold CSCS cards.
When to call us in North Hyde
Sunlight and weather break mastic down over time. It stiffens, stops stretching and cracks most of all on the sunniest and most exposed elevations.
Clients normally get in touch after noticing something like this:
- Repeated reactive repairs to the same buildings
- Patchy repairs in mismatched sealant
- Failed external movement joints
- Draught complaints from residents or tenants
For owners of several units at places like Endsleigh Industrial Estate (under half a mile north of North Hyde), one programme can deal with frame and external mastic across the lot.
What to look for in a quote
- Proof of insurance
- How joint depth will be controlled
- Whether old or failed sealant will be cut out, not overlaid
- Their pre-qualification and accreditations
When to bring in a specialist
Some joints are best left to specialists: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. A poor seal in places like these tends to cost more to put right later.
Using site staff can make sense for a small touch-up, but anything bigger is another matter: a specialist brings efficiency, a consistent finish and a 12-month guarantee.

London blocks come with residents to inform, access to agree and often a concierge or estate office to work with. We plan around the notices and access you arrange.
Trustees of buildings like St Leonard's Church can bring frame and external mastic into a planned maintenance list. Student blocks close to universities like University of London, 2.3 miles south-east of North Hyde, are easiest to work on between tenancies.

North Hyde: questions and answers
Will you take on work at estates like Endsleigh Industrial Estate, close to North Hyde?
Yes. We cover North Hyde and the area around it, including industrial estates, business parks and retail parks such as Endsleigh Industrial Estate. Photos and a short description are enough for a first look.
Do you take on jobs in North Hyde where loading and access are tightly controlled?
Yes, we plan every London job around the building’s own access rules. Send the building rules and access times with your enquiry.
Can you take on resealing for a block portfolio?
We do. Managing agents, property factors in Scotland, housing associations and landlords with block or commercial portfolios are our main clients for this work and work can be quoted per building or as a whole.
Can you plan resealing across several buildings?
Block-wide and estate programmes are common. You get a fixed quote per building or for the whole job.
What do you charge?
Every job gets its own fixed quote. To get one, give us a call on 01277 525 020 or send photos by email.
What if the old mastic contains asbestos?
Asbestos removal isn’t part of our work. Anything suspect is tested before we carry on in line with the dutyholder’s asbestos management.
Do you seal on top of existing sealant?
No. Failed sealant is removed and the faces cleaned back to sound, dry material first, since fresh sealant will not bond reliably to aged material.
