Mastic sealing for commercial buildings in Hainault
We work for building owners, landlords with commercial or block portfolios, managing agents and housing associations. Many prefer a planned programme to one-off visits, with each block quoted and scheduled in turn. If you have damaged joints in communal entrances and corridors and draughts at frames across a block, we can put it right, whatever the surface. One point of contact handles commercial sealant work in Hainault 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.
The 12-month guarantee is for workmanship rather than wear and tear. Sealant wears with time, and movement, weather, cleaning and use decide how fast, so we spell out the cover before we begin.

Questions we are asked in Hainault
Does your area include sites such as Newbury Retail Park, near Hainault?
Yes, sites like Newbury Retail Park are within our area, along with the rest of Hainault. To start, just ring 01277 525 020 or email drawings and photos with the unit, the joints involved and your access times.
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 do we ask for a quote?
It works in four steps: send details, get a quote, we seal, guaranteed. The first step only needs photographs and a postcode.
Which sealant will you use?
A specification, where there is one, decides it. Without one, the joint decides: its movement, its surfaces and what it has to cope with.
Can you send RAMS and CSCS details before starting?
Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we’ll confirm with the quote. We are CHAS accredited and a Constructionline member.
How long will the new sealant last?
There’s no fixed lifespan: movement, exposure, cleaning, traffic and the product all play a part. Treat them as maintenance items and inspect them regularly.
Will you quote for a small job?
Single areas, one-off repairs and whole buildings are all quoted the same way: send details, get a fixed quote, we seal, guaranteed.
On site: what to expect
In a busy building, the work is phased so only one area is out of use at a time. Each area is protected, prepared and sealed, then handed back before we move to the next. In Hainault, most buildings stay in use during the work, so zones and timings are agreed with whoever manages the building. Phased work keeps the rest of the building in use.
- First we look at the mastic on each building and note what needs replacing.
- A fixed quote follows, split by block or building if that suits you.
- The programme is fixed with you, including dates you can pass on to residents or tenants.
- Old sealant is stripped and each face prepared back to firm material.
- Backing rod and primer go in where the joint and the product need them, then new sealant is applied and tooled.
- Finished joints are looked over and the 12-month guarantee confirmed.
What we need from you
- Let building users know which areas are affected
- Make sure the joints can be reached
- Have the specification and drawings to hand
Ask for a quote
A good quote starts with a clear picture: the joints involved, quantities, access and the product called for. Send what you have, and we’ll arrange a site visit if anything is unclear.
Advice
Honest limits
Being straight saves everyone time. New sealant won’t cure:
- Water coming in from the roof or rainwater goods
- Old mastic suspected of containing asbestos, which must be tested and dealt with by a specialist first
- Leaks through the frame itself rather than the perimeter
Not sure which it is? You can speak to us on 01277 525 020 or email a schedule or drawings and we will tell you honestly before you book.

Why it’s worth doing now in Hainault
Reacting to every complaint means sending someone out block by block. A planned programme treats each building once, under a single quote and a single programme. Getting scaffold, permits or access booked in Hainault takes effort, so while access is arranged it pays to renew all failing joints, not just the worst.
Whether it’s a single area or a whole estate, the same things set the price: what’s in scope, how we reach it, what’s specified and when it needs doing. Call for a quote, and you will have a fixed figure to work with.

What the job involves on each surface
Planned maintenance
Adding mastic to planned maintenance avoids reactive repairs and spreads the work.
External movement joints
External movement joints take up expansion and contraction. Failed sealant in a movement joint lets water in.
Should maintenance staff do it?
Certain joints really need a specialist: 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.
A short, simple internal joint is often within reach of a maintenance team. Where it goes wrong is preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.
