Your questions answered
Will you take on a block within reach of South Ruislip station?
Yes, we work for agents, landlords and housing associations with blocks of every size. Send the address, photos of the elevations and your access arrangements, and we will give a fixed quote.
Do you take on jobs in Roxbourne where loading and access are tightly controlled?
Yes. Inductions, permits and timed loading are routine for us in London. Share the building’s contractor rules and we will work to them. The ULEZ covers the whole of Greater London, which we allow for
Do you work to architects’ specifications?
Yes. Include it with the drawings when you ask for a quote, and we’ll price the work to it, flagging anything that needs clarifying.
Do you check for asbestos in old sealant?
Asbestos removal isn’t part of our work. Anything suspect is tested before we carry on in line with the dutyholder’s asbestos management.
Do you seal on top of existing sealant?
No. Overlaying old sealant is a frequent cause of early failure, so everything comes out first.
How do you choose the sealant?
If the job is specified, we follow the specification. If not, we choose for the movement, the surfaces and the conditions, in line with the manufacturer’s guidance.
How do you reach windows on upper floors?
We talk through access for each building when we quote. Tell us the building height and any access already in place, and we will tell you how we’d approach it.
How we handle mastic sealing in Roxbourne
On a residential block, the work happens around people’s lives. The sequence, the areas and the dates are settled with you, giving you what you need to notify residents. Entrances and stairwells are kept in use throughout. If you’re dealing with damaged joints in communal entrances and corridors and no planned programme for sealant, we can put it right. Facilities teams, main contractors and managing agents in Roxbourne tend to want the same three things: a clear scope, tidy work and joints that don’t fail again.
For managing agents in Roxbourne, resident access, notice periods and the building’s rules shape the job. We work to the agent’s notice and access plan, so residents know what’s happening.
Work we carry out comes with a 12-month guarantee. Should something we installed fail, give us a call on 01277 525 020 or use the quote form and we will come back to it.

From enquiry to sign-off
A typical day starts with protection: tape along each joint edge and covers over finishes, stock and equipment close by. On site, the work typically takes a day or two for a single block, longer for an estate programme, and we clear our waste as we work. The ULEZ covers the whole of Greater London, and parking near a job is rarely simple. Let us know about any on-site parking or loading arrangements when you send the job details.
- A building-by-building inspection lists the failed joints.
- The quote is fixed and split as suits you.
- Dates and areas are agreed so occupiers can be told.
- Failed sealant is removed and the faces prepared.
- Joints are resealed and tooled.
- We check the finished work and confirm the guarantee.
What we need from you
- Share your working hours and any access restrictions
- Let building users know which areas are affected
- Point out any areas we must not close

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.

Quoting for work in Roxbourne
The price varies from site to site. It mainly depends on:
- How much there is to seal
- Specialist products, such as fire-rated or hygienic sealants
- Distance, for remote addresses
- Removal of failed or old sealant
Access often affects the price as much as the sealing: easy-to-reach joints are quicker than those that need equipment to get to. Mention the access as part of your enquiry.
What to include in your enquiry
There’s no need for a formal survey. These details are enough to start:
- Where the site is, with the postcode
- Specification clauses that apply
- Drawings or a marked-up plan, if available
- When you need the work done
Specifications, drawings and tender packages are welcome with any enquiry, and we’ll price against exactly what is specified. For smaller jobs, photographs and a description will do.
Signs you need mastic sealing in Roxbourne
Topping up old mastic is a common shortcut. New silicone has nothing to grip on old silicone, so these repairs rarely last.
Look out for the following:
- Draughts at frames across a block
- Patchy repairs in mismatched sealant
- Open joints in brickwork or panels
- Estate-wide sealant that is simply worn out
Churches, halls and community buildings such as St. Andrew’s Church are looked after by trustees and committees like any other owner, and their frames, doors and external joints need mastic renewed in time.
What your quote should include
- Health and safety accreditation such as CHAS
- The named product and why it was chosen
- How the existing material will be dealt with
- How they’ll work around occupants
Keeping the joints sound
To get the most from the new sealant:
- Check sealant joints during planned building inspections
- Have the asbestos survey to hand for older buildings
- Make it easy for occupiers to report draughts
- Group repairs into a planned programme
Include sealant in planned building inspections. Watch for splits, open gaps, hard or chalky surfaces and mastic pulling away, and note the building and elevation.
Mastic fails gradually, then all at once in a wet spell. Acting at the first signs keeps it a straightforward reseal and the complaints that come with it.

What else we do in Roxbourne
For managing agents and facilities managers
Building owners and managing agents use us on everything from one building to a spread of sites. One quote can cover more than one site, so there’s one set of paperwork to deal with.
Whether you’re a managing agent, a property factor or an owner’s representative: send details, get a fixed quote, we seal, guaranteed. We can agree access arrangements and keyholder contacts beforehand.
General trades versus a specialist
Putting right a botched joint often costs more than sealing it well at the start, because the whole bead must be removed and the faces cleaned back again. That’s why many clients bring in a specialist from the beginning.
Site maintenance staff can often handle a short internal joint. Where it goes wrong is preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.
