Send drawings, photos or a joint schedule, or tell us about the site, and we’ll come back with a fixed quote.
Should maintenance staff do it?
For most general trades, sealant is a sideline. A specialist prepares properly, controls joint depth and picks a product with the right movement class.
The visible bead is only part of the job. Correct depth, the right primer and a sealant matched to the movement are where general trades tend to cut corners.
Mastic sealing for commercial buildings in Speen
Owners and agents normally inherit a building’s mastic rather than choose it and it slowly wears out: it sits round windows and doors, along external joints and through communal areas. When it hardens, splits or pulls away, water and draughts follow, and occupiers start reporting it. We work on communal kitchens and washrooms, shopfronts below residential blocks and window and door perimeters on blocks, and the usual reasons a site gets in touch are window mastic that has split and shrunk and estate-wide sealant that is simply worn out. Whoever orders the work in Speen, the brief is normally the same: a fixed quote, no surprises on site and a 12-month guarantee behind the result.
For buildings around smaller places like Speen, we group work so one trip covers it. Send photographs of the frames and joints and we’ll give a fixed quote.
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’re clear about what is covered before work starts.

Aftercare for building managers
Your facilities or cleaning team can help the joints last. Share these points with them:
- Share the asbestos register when you send details
- Keep a record of when each building was resealed
- Mention RAMS, insurance or CSCS requirements up front
- Group repairs into a planned programme
Protect entrance and corridor joints from knocks where possible. Damage at low level is the most common reason communal joints fail early.
Leaks at window perimeters spoil finishes and can affect frames. Resealing early keeps the job small.
Leave it or put it right?
Draughts round window perimeters cost occupiers comfort, and they often blame the windows. In many cases, new perimeter sealant deals with it when the frames themselves are sound. Older rural buildings around Speen move with the seasons, and rigid or tired sealant can’t keep up. The right product, sized to the joint, copes much better.
The work involved drives the cost: stripping out, preparation, sealing, access and phasing. Call for a quote and we will explain how it’s made up.

Do you need mastic sealing in Speen?
Poor preparation explains many failed joints. Without clean, sound faces and a primer where the product needs one, the bead peels off one side.
These are often picked up first by site or facilities staff:
- Open joints in brickwork or panels
- The same joint failures repeated across a portfolio
- Complaints coming in block by block
- Water getting in round frames after rain
For owners of several units at places like Crownfield Industrial Estate, which lies west of Speen, one programme can deal with frame and external mastic across the lot.
Questions to ask before you book
- Will failed sealant be removed rather than covered?
- Their public liability cover
- What the guarantee covers, and for how long
- How they’ll work around occupants

A fixed quote reflects the actual work. It allows for:
- Joint width, depth and condition
- Location, for remote and island sites
- Whether the work must be split into stages
- Any access equipment needed
A quote for mastic joints depends on how many there are, their condition and the access, and any specification that applies. Ask us for a fixed quote.
Before you send an enquiry
For an accurate fixed quote, we need a clear picture of the site. Send us:
- The postcode of the building
- Whether the building will be occupied during the work
- The asbestos register, for older buildings
- Anything awkward about access or site hours
Specifications, drawings and tender packages are welcome with any enquiry, and we’ll price against exactly what is specified. For smaller jobs, photos and a description will do.
Questions about Speen
Is Speen off your patch?
Not at all: smaller places are covered as well as towns. We cover Greater London and the counties of the South East. Send photographs and a list of what needs doing, and we will plan the job to need as few trips as possible.
Will you take on a block within reach of Saunderton station?
Yes, we work for agents, landlords and housing associations with blocks of every size. We work to your notice and access arrangements.
How long do sealant joints last?
Nobody can honestly give a figure in years, since movement, weather, cleaning and use all affect it. Regular inspection is the best way to catch problems early.
How many days will you need on site?
We plan the time on site around your programme and access. We will give you an estimate of time on site when we quote.
Is asbestos a concern with old mastic?
Some mastics in pre-2000 buildings contain asbestos. We ask for the asbestos register or survey before work starts, and if it’s suspected, work stops until it’s tested.
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.
What about access for upper-floor joints?
We talk through access for each building when we quote. Tell us the number of storeys and whether scaffold or other access is planned and we will confirm the approach in the quote.
