Mastic sealing in Egham
For blocks and buildings in Egham and across Surrey, the process is the same: you send details, we return a fixed quote, the joints are resealed and the 12-month guarantee follows. Addresses, photographs of typical joints and a rough idea of quantities let us give a quick quote or we can visit. We work on balcony and threshold joints, shopfronts below residential blocks and communal kitchens and washrooms, and the usual reasons a site gets in touch are movement joints with sealant missing and window mastic that has split and shrunk. Searching for sealant specialists in Egham? We’ve been sealing commercial buildings since 2005.
Older buildings in towns like Egham have often had replacement windows fitted at different times, so mastic around them can be of mixed age and quality. A look at the whole building shows which joints need doing now.
What our 12-month guarantee covers is the way we did the job: the preparation, the sealing and the tooling. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

What the job involves on each surface
Tenement and older buildings
Natural stone can be marked by the wrong sealant, so we pick a grade that won’t mark it.
Commercial and mixed-use buildings
Commercial buildings have mastic at shopfronts, entrances and external joints. We work across portfolios on a planned basis.
When it isn’t the sealant
Before quoting, we check that sealant is the right answer. It isn’t the answer for:
- Frames that are rotten, warped or broken
- Masonry that has broken away beside the joint
- Misted or failed double-glazed units
If you are not sure, just call 01277 525 020 or email drawings and photos and we’ll give you a straight answer.
Surfaces we seal
- Window and door perimeters on blocks
- Communal entrances and stairwells
- Communal kitchens and washrooms
- Shopfronts below residential blocks
- External wall and movement joints
- Balcony and threshold joints
Common problems we fix in Egham
Sunlight and weather break mastic down over time. The surface chalks, the body stiffens and cracks appear, especially on south and west faces.
Most enquiries start with something like this:
- Failed external movement joints
- A mix of products and colours from past repairs
- Mastic failing across several blocks on an estate
- Complaints coming in block by block
If you manage student housing near a university such as Royal Holloway University, 0.8 miles to the west of Egham, the summer turnaround is the time for mastic.
What to look for in a quote
- How joint depth will be controlled
- Will RAMS and insurance details be available?
- How they’ll work around occupants
- Are they CHAS accredited or on Constructionline?
Should maintenance staff do it?
Paperwork matters too. Many sites expect CSCS cards, RAMS and proof of insurance, and our CSCS-carded applicators are used to working under those rules.
For a quick touch-up, site staff may be fine, but larger jobs are different: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.

Quoting for work in Egham
Each job is priced on its own details. The things that drive the figure:
- Backing rod, priming and other preparation
- Induction, permit and paperwork requirements
- Distance, for remote addresses
- How much there is to seal
Larger quantities, tricky access or phasing all shape the price. So do site requirements such as inductions and permits.
Sending details for a quote
Whether it’s one area or a whole building, the same details help:
- Asbestos survey details if the building is older
- The product your specification calls for
- When you need the work done
- The postcode of the building
Photos, drawings or a schedule of the joints are often enough for a fixed quote. If the job needs a look first, we will arrange a site visit.
Egham: questions and answers
Can you work at a site such as The Green Business Centre, by Egham?
Yes, sites like The Green Business Centre are within our area, along with the rest of Egham. Photos and a short description are enough for a first look.
Can you quote for a block close to Egham 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’ll quote and plan to suit.
What if the old mastic contains asbestos?
In older buildings, old mastic can contain asbestos. We check the asbestos register or survey before disturbing it, and if it’s suspected, work stops until it’s tested.
Do you supply RAMS and insurance details?
Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we’ll confirm with the quote. We are CHAS accredited and a Constructionline member.
Do you cover Egham?
Yes. We cover Egham, and the simplest way to start is to give us a call on 01277 525 020 or email drawings and photos.
Can weather delay the job?
Outside, yes. Sealant needs a dry joint and a temperature within the product’s range, so damp, frosty or very cold days can stop external work. Inside work is seldom held up.
Can you work to our specification?
Yes. The specification and the manufacturer’s installation guidance are what we work to, and any queries are raised before we start.
How a job runs
A typical day starts with protection: masking tape along the joint edges and sheeting over anything nearby. On site, the work normally takes anything from a day to a few weeks, depending on the number of buildings and joints, and our waste is bagged and taken away as we go. Parking and loading for town-centre jobs in Egham are worth mentioning when you send details. On estates and business parks it’s typically simpler.
- A building-by-building inspection lists the failed joints.
- The quote is fixed and split as suits you.
- We agree the programme and dates with you.
- Failed sealant is removed and the faces prepared.
- New sealant goes in with backing rod and primer where needed.
- We check the finished work and confirm the guarantee.
What we need from you
- Tell us your opening times and when work is allowed
- Point out any areas we must not close
- Confirm the product named in the specification

Specifications, drawings and tender packages are welcome with any enquiry, and we’ll price the work to it. For smaller jobs, photographs and a description will do.
