Islip: questions and answers
Is Islip too small for you to travel to?
Not at all. Islip is within our area. Our area covers London and the South East counties. Where we can, we group nearby jobs to make the most of each trip.
Does your area include sites such as Business Park, near Islip?
Yes. Estates, retail parks and business parks around Islip, Business Park among them, are all within reach. Photos and a short description are enough for a first look.
Can you follow the specification on our project?
Yes. We follow the specification, along with the manufacturer’s installation guidance, and we raise anything unclear before work begins.
Do you take on small jobs?
Single areas, one-off repairs and whole buildings are all quoted the same way: send details, get a fixed quote, we seal, guaranteed.
How long does a job like this take?
It depends on the scope, though a typical visit usually takes a few days for most blocks, with larger programmes scheduled building by building. For bigger or phased jobs, we’ll set out a timescale with the quote.
Can people stay in the building while you reseal?
Occupiers stay in the building throughout. If any flats or units need access, we will tell you in advance so you can arrange it with occupiers.
How much does the work cost?
We don’t publish prices, as every site differs. With photos or drawings, we can give you a fixed quote.
Mastic sealing in Islip, done properly
For over 20 years we have resealed joints for owners, agents and landlords. Our applicators are CSCS-carded and we hold public liability insurance. Resealed mastic joints in Islip carry our 12-month guarantee. We work on window and door perimeters on blocks, shopfronts below residential blocks and balcony and threshold joints, and the usual reasons a site gets in touch are draught complaints from residents or tenants and failed external movement joints. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: in Islip, that means joint design, primers and backing rod as standard.
For buildings around smaller places like Islip, we group work so one trip covers it. Send photographs of the frames and joints and we will give a fixed quote.
We stand behind the joints we seal: 12 months, guaranteed. It covers how we prepared and applied the sealant, and if something we did falls short, we return to it.

Looking after the joints
Sealant joints are maintenance items, and how long they last depends on how they’re treated. We suggest:
- Protect low-level joints in entrances
- Start inspections with the most exposed faces
- Ask residents or tenants to report leaks and draughts early
- Keep a record of when each building was resealed
Ask residents or tenants to report draughts or leaks round windows early. A quick report keeps a small repair small.
Budgets are easier to plan when sealant is part of planned maintenance. We can quote buildings in priority order and work down the list.
Site staff or a sealant specialist?
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.
Some joints are best left to specialists: for example fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. A poor seal in places like these tends to cost more to put right later.
How a job runs
When we get to site, we report to your site contact and complete whatever induction the building runs. Floors, finishes and fittings next to the joints are covered before anything is cut or cleaned, and the work usually takes anything from a day to a few weeks, depending on the number of buildings and joints. For a building around Islip, tell us how to find it and who will meet us. Send that with the details and we will confirm the plan with the quote.

- The products and programme are set out in a fixed quote.

Advice
Blocks and managed buildings in Islip
Central London is about 54 miles from Islip. Commuter-belt towns tend to have plenty of managed blocks near stations and town centres; their frame mastic often ages block-wide. The South East is one of the drier parts of the UK. External mastic still waits for dry faces and the right temperature, and the sunniest, most exposed sides of a building typically need attention first.
Older community buildings, St Nicholas' Church among them, often have frames of mixed ages whose mastic varies. For agents with blocks near Islip station (under half a mile north of Islip), a block-wide mastic programme deals with frames, balconies and entrances in one go.

Why act early in Islip
Resealing ahead of leaks keeps it to a maintenance task. Once water has tracked in, the repair list grows, and the complaints come with it. Around Islip, it’s better to renew all the failing joints at once. Send photographs of each area and we will quote for the lot.
The specified product makes a difference, and so does the preparation, from cutting out to priming and backing rod. Access, phasing and site requirements come into it too.

Do you need mastic sealing in Islip?
Many failed joints were sealed without backing rod, so the mastic is glued to the joint bottom too. That three-sided adhesion stops it stretching and splits as the building moves.
Clients normally get in touch after noticing something like this:
- Worn sealant at communal door frames
- Failed external movement joints
- Complaints coming in block by block
- Leaks at window and door perimeters
Landlords with units on estates such as Business Park, 2.5 miles north of Islip, can bring frame, door and external mastic across several units into one programme.
