Share the site address and what’s failing, and we’ll reply with a fixed quote or arrange a visit.
From enquiry to sign-off
On arrival, we sign in, go through any site induction and check how permits are handled. Everything around the joints gets protected before any cutting starts, with the work itself typically taking a few days for most blocks, with larger programmes scheduled building by building. Smaller jobs around Horton can be grouped with others nearby, which keeps travel down. You’ll have a fixed quote before work starts.
- 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 sequence and the dates are fixed with you, giving you what you need to notify occupiers.
- We remove the old mastic completely and clean the joint faces back.
- Deep joints get backing rod, faces are primed if the manufacturer specifies it, then the joint is sealed and tooled.
- Completed joints are inspected and carry a 12-month workmanship guarantee.
Getting the site ready
- Let building users know which areas are affected
- For older buildings, check the asbestos register before work
- Agree which areas must stay open

Mastic sealing for commercial buildings in Horton
On a residential block, the work happens around people’s lives. Dates, areas and the order of work are agreed with you in advance so you can let residents know what is happening. Communal entrances and stairs stay usable while we work. If you have occupiers reporting cold air round windows and old repairs sealed over failed mastic, we can help. A single leaking joint is often how a building in Horton first comes to us: we look at the rest while we are there and tell you what we find.
Around smaller places like Horton, older walls fitted with newer windows are a familiar sight. The mastic needs to suit an irregular masonry face and the look of the building.
Work we carry out comes with a 12-month guarantee. Should something we installed fail, phone 01277 525 020 or email drawings and photos and we’ll come back to it.

Cost factors for mastic joints
The price varies from site to site. Expect it to depend on:
- The size and state of each joint
- The product specified
- Site requirements such as inductions and permits
- Quantities, in metres or numbers
The work involved drives the cost: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a fixed quote and we’ll explain how it’s made up.
What we need to price the job
There’s no need for a formal survey. These details are enough to start:
- How the joints are reached, and at what height
- Any dates the work must fit around
- The postcode of the building
- The asbestos register, for older buildings
Pricing a project or setting a maintenance budget? We’ll quote against your scope and drawings that you can work with. For a chat about it beforehand, call the office on 01277 525 020 or send photos by email.
Owners, agents and contractors
Facilities managers want contractors who arrive with the paperwork sorted. Tell us what site paperwork you need, such as RAMS, an insurance certificate or CSCS details, and we’ll confirm with the quote.
We take on planned maintenance as well as one-off repairs: working through a building or an estate in stages that fit your budget. Horton can form part of a wider programme across Windsor and Maidenhead.
Questions about Horton
Can you quote for a block close to Sunnymeads station?
Yes. Blocks of any size are within what we do. Give us the building’s details and say how residents are notified, and we will quote and plan to suit.
Will you take on work at estates like Lakeside Industrial Estate, close to Horton?
Yes. Estates, retail parks and business parks around Horton, Lakeside Industrial Estate among them, are all within reach. Photos and a short description are enough for a first look.
How do you handle work on occupied blocks?
We plan around people living or working in the building. We agree the programme so you can notify occupiers, and entrances stay in use.
Will you just go over the old sealant?
No. We cut the old material out and clean the joint back before sealing, since fresh sealant will not bond reliably to aged material.
How soon can the area be used again?
We’ll confirm how long the chosen product needs to cure, and sign any area that should be left alone.
Do you work with property factors and landlords?
Yes, block and estate work is a core part of what we do. Buildings are scheduled in turn with dates agreed in advance.
Can you work to our specification?
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.
Site staff or a sealant specialist?
Some joints are best left to specialists: for example fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. Getting these wrong usually costs more in the end than doing them right.
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.
Mastic sealing in Horton: the local picture
Horton is in the South East, one of the UK’s drier regions. Outside mastic still needs a dry joint and the right temperature, and the sunniest, most exposed sides of a building normally need attention first. Horton is about 19 miles from central London. Managed blocks of flats are a big part of commuter-belt property.
If you own or manage units on a site such as Lakeside Industrial Estate, 1.8 miles north-east of Horton, failed mastic on frames, door surrounds and external joints can be dealt with unit by unit. Trustees of buildings like Church of St Michael can bring frame and external mastic into a planned maintenance list. If you manage student housing near a university such as Royal Holloway University, 3.4 miles to the south of Horton, the summer turnaround is the time for mastic.
Horton is about 3 miles north of Egham, in Windsor and Maidenhead. We send applicators to Horton for mastic joints. 60 places across Windsor and Maidenhead fall within our area, Horton among them. Our London page has more on work in that area (19 miles or so).

Not far away are Staines Reservoirs.
After the work
Keep the joints in good shape with a few simple steps:
- Include mastic in your cyclical inspections
- Plan resealing building by building rather than complaint by complaint
- Look at the sunniest and most exposed elevations first
- Keep a record of when each building was resealed
Keep records of when each building was resealed. That makes future programmes easier to plan and gives you a history.
Joints on a building age together, so it pays to look at the whole elevation. A planned reseal saves repeated visits.
Different surfaces, different methods
Estate-wide resealing programmes
An estate of similar buildings suits a rolling programme. Each block is priced and scheduled in order.
Tenement and older buildings
Natural stone can be marked by the wrong sealant and we choose accordingly.
