When it isn’t the sealant
Being straight saves everyone time. Fresh joints won’t solve:
- Substrate edges that need repairing first
- Water coming in from the roof or rainwater goods
- Materials that need asbestos testing before work

Mastic sealing in Nuptown, done properly
Our clients include managing agents, property factors in Scotland, housing associations and landlords with block or commercial portfolios. Many prefer a planned programme to one-off visits and we quote and schedule each building in turn. We work on window and door perimeters on blocks, external wall and movement joints and balcony and threshold joints, and the failures we’re asked to look at most are open joints in brickwork or panels and worn sealant at communal door frames. For commercial sealant work in Nuptown, you deal with one contact from quote to sign-off, whether it’s one building or several.
For owners with a single building near Nuptown, we plan to finish in one visit where possible. Send photographs of the frames and joints and we will give a fixed quote.
Building owners and contractors get the same cover: twelve months on the work we carried out. Faults in the structure, damage and other trades’ work fall outside it, and we say so plainly.

How a job runs
Where the site stays busy, we agree a sequence with your contact so the disruption stays in one area at once. Each section is protected, cleaned back and sealed, then reopened once the sealant allows before we move to the next. For work around Nuptown, we aim to finish in one visit, so we ask for photos and rough sizes first. Then the right materials arrive with us.
- First comes a look at the joints and, for older buildings, the asbestos records.
- A fixed quote covers the joints, products and order of work.
- We strip out the old sealant.
- The joints are prepared and resealed with the right product.
- We finish each building before moving to the next.
Preparing the site
- Flag any permit to work we will need
- Share your working hours and any access restrictions
- Warn occupants and staff about the work

Related advice
Site staff or a sealant specialist?
Site maintenance staff can often handle a short internal joint. The usual problems come from preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.
For most general trades, sealant is a sideline. A specialist prepares properly, controls joint depth and picks a product with the right movement class.
What else we do in Nuptown
What the job involves on each surface
Tenement and older buildings
Some old mastics in pre-2000 buildings contain asbestos and the register is checked before anything is disturbed. If it’s suspected, work stops until it’s tested.
External movement joints
Joint size and product are matched to the expected movement with the width-to-depth ratio set as the manufacturer advises.
Questions about Nuptown
Is Nuptown too small for you to travel to?
Not at all. Nuptown is within our area. 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.
Will you take on a block within reach of Bracknell station?
Yes, we work for agents, landlords and housing associations with blocks of every size. We work to your notice and access arrangements.
What about access for upper-floor joints?
It depends on the building. How upper joints are reached is agreed before work is booked so the fixed quote reflects it.
How long before the joints can be used?
We’ll confirm how long the chosen product needs to cure, and flag anything to keep off until it has cured.
Do you work for managing agents and housing associations?
Yes, that’s exactly who this service is for. Buildings are scheduled in turn with dates agreed in advance.
Can you send RAMS and CSCS details before starting?
We’re CHAS accredited, a Constructionline member and carry public liability insurance. For specific documents, tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we’ll confirm with the quote.
Is mastic sealing guaranteed?
A 12-month guarantee covers our work. It applies to our workmanship rather than damage or problems with the frames.
Owners, agents and contractors
Facilities managers want contractors who arrive with the paperwork sorted. Let us know the documents you need (RAMS, insurance certificate, CSCS details) and we’ll confirm them with the quote.
If you look after buildings for someone else, clear figures and clear communication matter. We quote a fixed sum, confirm the scope and walk the finished work with you or your representative, plus a 12-month guarantee.
Why act early in Nuptown
Draughts round window perimeters cost occupiers comfort, and they often blame the windows. In many cases, new perimeter sealant deals with it where the frames themselves are sound. Halls, stores and units around places like Nuptown may not be checked every day, which gives a failed joint time to do damage. Renewing joints in good time avoids the problem.
Access can matter as much as the joints themselves: joints within easy reach take less time than ones that need access equipment. Tell us how the joints are reached and call for a quote.

Blocks and managed buildings in Nuptown
Nuptown lies roughly 27 miles out from central London. Managed blocks of flats are a big part of commuter-belt property. Nuptown sits in one of the drier corners of the country, the South East. External mastic still waits for dry faces and the right temperature, and elevations facing the sun and the prevailing weather are normally where frame mastic ages first.
If you manage student housing near a university such as Imperial College Silwood Park Campus, 4.6 miles to the south-east of Nuptown, the summer turnaround is the time for mastic. Churches, halls and community buildings such as Church of St Michael and All Angels are looked after by trustees and committees like any other owner, and their frames, doors and external joints need mastic renewed in time. Historic properties like St Leonard's Hill, 3.5 miles east of Nuptown, show the age of some local stock, where frame mastic must suit soft brick or stone.
