Mastic sealing for commercial buildings in Laleham
Across Laleham and the rest of Surrey, we work the same way: you send details, we return a fixed quote, the joints are resealed and the 12-month guarantee follows. A list of buildings, a few photos and approximate joint numbers are enough for a quick quote, and site visits can be arranged. If you have worn sealant at communal door frames and draught complaints from residents or tenants, we can put it right. For commercial sealant work in Laleham, you deal with one contact from quote to sign-off, whether it’s one building or several.
In a smaller place such as Laleham, landlords and agents tend to look after small blocks, flats over shops, sheltered housing and commercial units. Their window perimeters and external joints need renewing as the mastic ages.
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 are clear about what is covered before work starts.

Questions we’re asked in Laleham
Will you take on a block within reach of Staines station?
Yes. Blocks of any size are within what we do. Send the address, photos of the elevations and your access arrangements, and we’ll give a fixed quote.
Does your area include sites such as Pine Trees Business Park, near Laleham?
Yes. Our area takes in Laleham and its surroundings, with estates and business parks such as Pine Trees Business Park included. A few photos and the unit address let us price the work.
Do you work for managing agents and housing associations?
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.
How many days will you need on site?
The duration is planned around your programme and the access we’re given. You will have an expected duration with the quote.
When is resealing likely to be due?
There isn’t a single answer, since movement, weather, cleaning and use all affect it. Regular checks let you plan resealing before leaks or damage.
Do you guarantee the mastic work?
Every building we reseal has a 12-month guarantee. It covers our workmanship, not later building movement, damage or frame failures.
What about access for upper-floor joints?
It depends on the building. How upper joints are reached is agreed before work is booked so there are no surprises.
When to call us in Laleham
Buildings move with temperature and moisture, and every joint has to stretch and squeeze with them. If the joint or the product wasn’t suited to the movement, it splits and fails early.
Most enquiries start with one or more of the following:
- Damp patches beside frames
- Brittle perimeter mastic across a building
- Worn sealant at communal door frames
- The same joint failures repeated across a portfolio
Buildings close to stations like Staines station (to the north-west of Laleham) are often flats over shops, with frame mastic to keep sound.
What to look for in a quote
- Their pre-qualification and accreditations
- Will failed sealant be removed rather than covered?
- Their public liability cover
- Will CSCS-carded applicators be on site?
What we can’t put right
Honesty saves time and money. New sealant won’t cure:
- Failed window or door frames, which need a window contractor
- Misted or failed double-glazed units
- Old mastic suspected of containing asbestos, which must be tested and dealt with by a specialist first
Not sure which it is? You can give us a call on 01277 525 020 or send photos by email and we will tell you honestly before you book.
What we seal
- Shopfronts below residential blocks
- External wall and movement joints
- Window and door perimeters on blocks
- Communal entrances and stairwells
- Balcony and threshold joints
- Communal kitchens and washrooms
Owners, agents and contractors
Agents, factors and owners’ representatives all follow the same route: send the details, accept a fixed quote, and we carry out and guarantee the work. We can agree access arrangements and keyholder contacts beforehand.
Planned maintenance programmes are welcome: working through a building or an estate in stages that fit your budget. Laleham can form part of a wider programme across Surrey.

Diagnose, treat, sign off
The first thing on site is a walk round with your contact, to confirm the scope, the order of work and any areas we must keep clear. After that, any old or failed material is removed, each joint is prepared and the new sealant goes in. Work in places the size of Laleham is planned as a single visit where we can. Clear photos and measurements help us bring the right products.
- First we look at the mastic on each building and note what needs replacing.
- We send a fixed quote that sets out the joints, the products and the programme.
- The programme is fixed with you, including dates you can pass on to residents or tenants.
- We remove the old mastic completely and clean the joint faces back.
- 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.
Before we start on site
- Explain the parking and delivery arrangements
- Tell us which areas need to stay in use
- Flag any permit to work we’ll need

How the job changes by surface
Communal areas
Joints at low level in communal areas take knocks from bins, bikes and buggies and tend to fail first.
External movement joints
Brickwork, blockwork and panel joints let a building move. Failed sealant in a movement joint lets water in.
When to bring in a specialist
General builders and handymen seal joints, but it isn’t their main trade. A specialist prepares properly, controls joint depth and picks a product with the right movement class, which is what makes a joint last.
For a quick touch-up, site staff may be fine, but anything bigger is another matter: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.
Mastic sealing around Laleham: how the place shapes the job
Laleham is about 18 miles from central London. Managed blocks of flats are a big part of commuter-belt property, and window and balcony mastic on them tends to age at the same rate. Rainfall across the South East, Laleham included, is lower than in many parts of the UK. Even so, frame mastic only goes on in dry, workable conditions, and the sunniest, most exposed sides of a building normally need attention first.
If you manage student housing near a university such as Royal Holloway University, 3.3 miles west of Laleham, the summer turnaround is the time for mastic. If you own or manage units on a site such as Pine Trees Business Park, 1.6 miles to the north-west of Laleham, failed mastic on frames, door surrounds and external joints can be dealt with unit by unit.
