Common questions from Horn Park clients
Do you take on jobs in Horn Park where loading and access are tightly controlled?
Yes, most London buildings have access rules of some kind, and we plan around them. Send the building rules and access times with your enquiry.
Could you schedule work at a campus like University of Greenwich - Avery Hill for the vacation?
Yes. We plan campus work around teaching, exams and residence turnarounds. Let us know which documents your site asks for, and we’ll confirm them alongside the quote.
How long does a typical visit take?
That varies with the scale of the job, but the work normally takes as long as the agreed sequence needs, which comes down to joint lengths, access and handover dates. For bigger or phased jobs, we will set out a timescale with the quote.
How soon can the area be used again?
The product and site conditions decide that. Some take light use quickly, others need longer to cure, so we’ll confirm the curing time on the day.
Can you work to our specification?
Yes. Send it with your enquiry, and we’ll price the work to it.
What joints do you seal on a new build?
It depends on the specification, but frames, sanitary, kitchens, caulk where specified and snagging are typical.
What do you charge?
Each job is quoted on its own details. For yours, speak to us on 01277 525 020 or send details through our quote form.
Construction mastic for commercial buildings in Horn Park
Mastic Doctor has been a subcontractor on construction projects for over 20 years. We price from drawings and the specification, agree the sequence with the site team and seal as areas are released. To price a package in Horn Park, send drawings and the specification through our quote form. If you have perimeter gaps outside the sealant’s range and new external sealant already peeling away, we can put it right, on cladding and panel joints, sanitary and kitchen joints and brick and block movement joints alike. Most enquiries from Horn Park start with one failed joint and grow into a wider look at the building: we look at the rest while we’re there and tell you what we find.
A great deal of London construction is refurbishment of occupied or part-occupied buildings, alongside new blocks. Replacement windows, recladding and fit-outs leave perimeter and facade joints to seal, often next to people still using the building, so tidy, well-planned work matters.
We stand by our work: 12 months, guaranteed. It covers how we prepared and applied the sealant, and if something we did falls short, we return to it.

Why it’s worth doing now in Horn Park
Refurbishments sometimes budget for new windows when the frames are sound and only the seal has failed. Sound frames often need only a new perimeter seal. If the frame is life-expired, we’ll tell you. Failed sealant in a building in Horn Park can quickly affect neighbours, tenants or the floor below. Putting it right early is less disruptive than dealing with the consequences.

New build and refits around Horn Park
Site traffic in Horn Park falls within London’s ULEZ, like everywhere else in Greater London. Delivery slots and scarce storage shape how and when the mastic goes in. Horn Park has a good number of hotels close by, all within 2 miles. When hotels extend or refit, the work is normally squeezed between peak periods, mastic included.
Units on estates such as Chiltonian Industrial Estate (0.7 miles west of Horn Park) tend to be reclad and refitted as tenants change, and each job leaves cladding and perimeter joints to seal. Projects at colleges like Hadlow College (to the south of Horn Park) tend to run to term dates, so the mastic is planned tightly. On a campus such as University of Greenwich - Avery Hill, 2.2 miles to the east of Horn Park, new teaching buildings and residences are usually built and refurbished around the academic year.

Building owners, agents and FMs in Horn Park
Blocks and communal areas make up much of the work for housing associations and agents. Work can be phased so residents and staff keep access throughout, with each stage agreed with your site contact.
Planned maintenance programmes are welcome: resealing failed joints building by building, on a schedule that suits your budget. Horn Park can form part of a wider programme across Greater London.
Diagnose, treat, sign off
When we get to site, we report to your site contact and complete whatever induction the building runs. Everything around the joints gets protected before anything is cut or cleaned, and the work normally takes a day or two on a small fit-out and several weeks on a large multi-storey package. In Horn Park, most buildings stay in use during the work, so we agree zones and timings with the building or facilities manager. Areas are handed back as each section is finished.
- First we look at the scope on site or from drawings.
- You receive a fixed quote covering scope, products and sequence.
- Site paperwork is confirmed and our CSCS-carded applicators are inducted.
- We seal plot by plot or floor by floor in line with the programme.
- Problems we find, such as oversized gaps, are raised right away.
- The package is closed out, snags cleared and backed by our 12-month guarantee.
What we need from you
- Share the asbestos register for older buildings
- Share your working hours and any access restrictions
- Agree which areas must stay open

Send us photos, drawings or a joint schedule are often enough for a fixed quote. If the job needs a look first, we will arrange a site visit.

What sealant work can’t fix
A few problems need another trade or a different fix, and we say so rather than covering them up:
- Frame gaps too wide for sealant, which the installer needs to correct
- Specifying the product where the designer hasn’t
- Fire-stopping design or sign-off (that’s for the designer, fire engineer and building control)
Not sure which it is? You can give us a call on 01277 525 020 or use the quote form and we’ll tell you honestly.
What we seal
- Window and door perimeters
- Brick and block movement joints
- Floor and skirting junctions
- Cladding and panel joints
- Internal decorators’ caulk
- Sanitary and kitchen joints
Site staff or a sealant specialist?
For most general trades, sealant is a sideline. A specialist prepares properly, controls joint depth and picks a product with the right movement class, which is what makes a joint last.
Paperwork matters too. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and we will confirm the paperwork you need with the quote.
Maintenance after handover
Regular inspection catches problems early. Specifically:
- Put any product change through the designer first
- Ask cleaners to use soft cloths around fresh sealant
- Protect sealed areas from following trades
- Allow flexibility for external sealing in damp or cold weather
Brief the sparkle clean so they don’t scrape the new joints. Blades and abrasive pads are the commonest cause of damage at the final clean, so stick to soft cloths and gentle cleaners near sealant.
One unsealed frame can let water into finished internal areas. On a new building that means remedial work after decorating, and a delay to handover. Checking perimeters before internal finishes go on avoids it.
