Questions we are asked in Farnham
Do you cover business parks and estates near Farnham, such as Hookstile Trading Estate?
Yes. Our area takes in Farnham and its surroundings, with estates and business parks such as Hookstile Trading Estate included. To start, just phone 01277 525 020 or use the quote form with the unit, the joints involved and your access times.
Will you plan work around the academic year at somewhere like University for the Creative Arts?
Yes. Education sites usually want the work in vacations or in phases during term, and we plan to suit. Let us know which documents your site asks for, and we’ll confirm them alongside the quote.
Are you insured?
Yes. We’re fully insured, and the certificate can go with your quote.
Do you do internal caulk as well as external mastic?
Inside and out: frame perimeters, movement joints, caulk where called for, sanitary and kitchens, all priced as one package.
What happens if old sealant might contain asbestos?
The duty to manage asbestos sits with the building’s dutyholder, so for older buildings we ask for the asbestos register first. If anything suspect turns up, we stop until it’s tested.
Can you follow the specification on our project?
Yes. Send it with your enquiry, and we will price the work to it, flagging anything that needs clarifying.
Can staff carry on working while you’re here?
Yes, as long as we plan it. We agree a sequence with your contact so just one area at a time is disrupted.
Construction mastic in Farnham, done properly
The programme rarely stands still, so the mastic package has to flex with it. The sequence is set with the site team and updated as plots or floors are handed over and we don’t seal before other trades have finished in an area. That keeps the work right first time and saves rework. Most enquiries involve caulk cracking where joints are moving more than expected and sealant knocked or painted over by other trades, across sanitary and kitchen joints, internal decorators’ caulk and brick and block movement joints. A single leaking joint is often how a building in Farnham first comes to us: we check the joints around it and give you an honest view of what needs doing now and what can wait.
For contractors on site in a town like Farnham, the mastic has to fit the programme: perimeters sealed before scaffold is struck, internal sealant after decoration, snags before handover. Send drawings and the programme and we’ll price to suit.
Our 12-month guarantee is about workmanship, not wear and tear. How long a sealant joint lasts depends on movement, exposure, cleaning and use, so we are clear about what is covered before work starts.

Sites and facades in and around Farnham
The South East is one of the drier parts of the UK. That doesn’t stop wet spells, or frosty starts that leave panels too damp to seal, so the external programme keeps a little slack. The area within 2 miles of Farnham holds several hotels. Hotel extensions and refits typically have to fit around bookings, so mastic dates are tight.
Extensions at sites like Farnham Community Hospital (0.9 miles north-east of Farnham) normally sit beside working departments, and the mastic follows strict access rules. For contractors on a campus like University for the Creative Arts, 0.6 miles to the north-west of Farnham, facade and perimeter sealing has to fit around students and term dates.
Farnham is about 6 miles south of Farnborough, in Surrey. If you are looking for construction mastic in Farnham, we can help, as we do across Surrey. We work across 379 places in Surrey, large and small. There’s a separate page for Reading, about 18 miles away.
We take on mastic packages across the GU9 and GU10 postcode area. Among the streets we cover are Barncroft, Approach Road and Saxon Croft, and sites on any of them can send details for a fixed quote. Farnham sits on or close to the A31 and A287, useful when we plan access and materials. Just outside Farnham, we also work in Compton (1 mile east), Hale (1 mile north), Upper Hale (2 miles north), Runfold (2 miles east) and Heath End (2 miles north). Nearby towns on our patch include Guildford (10 miles east), Woking (12 miles north-east), Camberley (9 miles north), Frimley (8 miles north), Haslemere (9 miles south) and Cranleigh (14 miles east). Farnham is one of the busier places in Surrey, and its commercial and public buildings are all within our area.
What’s near Farnham
Locally, jobs take us to sites close to Moor Park, William Cobbett Public House and Weydon School. Farnham has its own railway station: Farnham station. Nearby you’ll also find Museum of Farnham (under half a mile north-west) and Farnham Castle (0.6 miles north-west). Not far away are Farnham Park and Aunt's Pool.
Signs you need construction mastic in Farnham
Frames installed with uneven gaps make perimeter sealing harder. Sealant has a range of joint widths it can cope with, so gaps outside that range need sorting by the installer first. Better to raise it at the start than seal a joint that’s bound to fail.
Common reasons buildings call us in:
- Existing joints on a refurb that need cutting out and resealing
- Snag items on joints that need redoing before handover
- Sealant knocked or painted over by other trades
- Caulk cracking where joints are moving more than expected
Hotel extensions and refits, at places such as Hotel de Vie, under half a mile south of Farnham, usually run between busy periods, so the sealing is squeezed into short windows.

- What the guarantee covers, and for how long
- Are they CHAS accredited or on Constructionline?
- Will RAMS and insurance details be available?
Maintenance after handover
To get the most from the new sealant:
- Share drawings and the specification as soon as possible
- Record the products used in the O&M file
- Keep scrapers and abrasive pads off new beads
- Don’t schedule sealing before decorators and flooring are done
After we’ve sealed an area, it helps to keep other trades from damaging the joints. New beads should be left to cure before cleaning or decorating nearby, and that time depends on the product, temperature and joint depth.
Sealing outside when the joint is damp or too cold leads to poor adhesion. Waiting for a dry joint and the right temperature is better than redoing work.

Should maintenance staff do it?
Paperwork matters too. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and our CSCS-carded applicators are used to working under those rules.
Putting right a botched joint often costs more than sealing it well at the start, since all of it has to come out and the faces be cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.
When it isn’t the sealant
Being straight saves everyone time. Fresh joints won’t solve:
- Specifying the product where the designer hasn’t
- Frame gaps too wide for sealant, which the installer needs to correct
- Damage to finishes by other trades after we have sealed
If you’re not sure, just phone 01277 525 020 or email a schedule or drawings and we’ll give you a straight answer before you book.
