Mastic sealing in Sidlow, done properly
On a residential block, the work happens around people’s lives. Dates, areas and the order of work are agreed with you in advance so you can let residents know what is happening. Communal entrances and stairs stay usable while we work. The enquiries we see most involve complaints coming in block by block and the same joint failures repeated across a portfolio, on window and door perimeters on blocks, external wall and movement joints and communal kitchens and washrooms. Looking for mastic applicators who cover Sidlow? We have been sealing commercial buildings since 2005, with CSCS-carded applicators.
In and around smaller places like Sidlow, landlords and agents often look after small groups of housing association properties, converted farm buildings and community buildings. Frame and wall-joint mastic on all of them ages and hardens.
Work we carry out comes with a 12-month guarantee. If an installation problem shows up, ring 01277 525 020 or send photos by email and we’ll arrange a return visit.

How the job changes by surface
Tenement and older buildings
Some old mastics in pre-2000 buildings contain asbestos, so we check the asbestos register or survey first. If it’s suspected, work stops until it’s tested.
External movement joints
Movement joints are cleaned out, backed with rod and resealed with a sealant of the right movement class.
General trades versus a specialist
Some joints are best left to specialists: for instance fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. Getting these wrong usually costs more in the end than doing them right.
General builders and handymen seal joints, but it isn’t their main trade. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint, which is what makes a joint last.
Common problems we fix in Sidlow
Sunlight and weather break mastic down over time. The surface chalks, the body stiffens and cracks appear most of all on the sunniest and most exposed elevations.
Things that normally lead to an enquiry:
- The same joint failures repeated across a portfolio
- Draughts at frames across a block
- A mix of products and colours from past repairs
- Leaks at window and door perimeters
If you look after a block within reach of Salfords station (1.8 miles east of Sidlow), frame and balcony mastic can be renewed on one programme.

What happens if it’s left?
Reacting to every complaint means sending someone out block by block. Planned resealing covers a whole building or estate in one go and is simpler to manage and budget. For buildings around smaller places like Sidlow, water damage can go unnoticed for longer, especially where a building isn’t used daily, so a failed joint can leak for a while before anyone sees it. Renewing joints in good time avoids the problem.
What a job costs comes down to how many linear metres there are, how much old material needs removing and how the joints are reached. Call for a quote once you have the details.

Advice
Blocks and managed buildings in Sidlow
Sidlow is in the South East, one of the UK’s drier regions. Even so, frame mastic only goes on in dry, workable conditions, while the elevations that take the most sun tend to show hardened mastic first. Sidlow lies roughly 21 miles out from central London. Managed blocks of flats are a big part of commuter-belt property.
Churches, halls and community buildings such as Emmanuel Church are looked after by trustees and committees like any other owner, and their frames, doors and external joints need mastic renewed in time. For a school such as Dovers Green School, perimeter mastic on windows and doors is a holiday job.

Questions about Sidlow
Is Sidlow too small for you to travel to?
No. Places such as Sidlow are covered as much as the big towns. We cover Greater London and the counties of the South East. Send photos and a list of what needs doing, and we will plan the job to need as few trips as possible.
Does your area include sites such as Fontigarry Farm Business Park, near Sidlow?
Yes. We cover Sidlow and the area around it, including industrial estates, business parks and retail parks such as Fontigarry Farm Business Park. Send details of the unit and the work through our quote form for a quick quote.
Do you take on small jobs?
Small jobs are welcome alongside larger packages. Send details for a fixed quote.
When can the area be used after sealing?
We will confirm how long the chosen product needs to cure, and flag anything to keep off until it has cured.
Does weather matter for sealant work?
For external joints, yes. Sealant needs a dry joint and a temperature within the product’s range, so frost, rain or cold mornings can delay outside work. Internal work is rarely affected.
Do you need to see the site first?
It depends on the job. Simple work can often be priced from photos, and bigger or more complex jobs normally get a visit.
How do you reach windows on upper floors?
It depends on the building. We agree access with you at quote stage so there are no surprises.
Cost factors for mastic joints
There’s no standard rate for sealant work, since sites vary so much. What we take into account:
- Removal of failed or old sealant
- How accessible the joints are
- Joint width, depth and condition
- The product specified
Access often affects the price as much as the sealing: easy-to-reach joints are quicker than those that need equipment to get to. Tell us how the joints are reached and call for a quote.
Before you send an enquiry
We can often quote from photographs and a few details. Please tell us:
- The postcode of the building
- The product your specification calls for
- Drawings or a marked-up plan, if available
- The type of building and who uses it
For a fixed quote, call the office on 01277 525 020 or send details through our quote form with the site address and an outline of the work. Our quote form is another easy route.
