Why deal with it now?
Sealing over damaged or contaminated new joints might save a day, but it rarely lasts. New sealant laid on old or dirty sealant has nothing to bond to, and the defect comes back after handover. We cut out and redo the joint properly. Converted and older buildings near places like Sidlow tend to move, and aged sealant cracks. The right product, sized to the joint, copes much better.
The work involved drives the cost: stripping out, preparation, sealing, access and phasing. Call for a fixed quote.

Construction mastic in Sidlow, done properly
Most of the packages we price run well beyond frames: external door and window perimeters, internal decorators’ caulk where specified, sanitary joints in bathrooms and washrooms, kitchen worktops and splashbacks, and snagging before handover. Splitting those between trades often leaves gaps in responsibility. The enquiries we see most involve bath and shower joints scraped during the final clean and frame perimeters left unsealed or poorly sealed, across sanitary and kitchen joints, brick and block movement joints and floor and skirting junctions. A specialist sealant contractor works differently from a general builder: on jobs in Sidlow, preparation and product choice get the time they need.
Sites around smaller places like Sidlow can be a fair drive from suppliers, so we come with everything the package needs. Drawings, photos and the programme let us give a fixed quote.
The 12-month guarantee covers our workmanship: preparation, application and finish. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

Your questions answered
Is Fontigarry Farm Business Park, near Sidlow, within your area?
Yes. Our area takes in Sidlow and its surroundings, with estates and business parks such as Fontigarry Farm Business Park included. To start, just ring 01277 525 020 or send photos by email with the unit, the joints involved and your access times.
Is a hospital such as East Surrey Hospital somewhere you can work?

How many days will you need on site?
The duration is planned around your programme and the access we’re given. You will have an expected duration with the quote.
When can the area be used after sealing?
The product and site conditions decide that. Some take light use quickly, others need longer to cure, so we’ll confirm the curing time on the day.
Can the sealant be colour-matched?
Often, yes. Sealants are made in a wide range of standard colours, and matching to RAL references or nearby finishes is commonly requested. We confirm what’s available for the specified product when we quote.

When something else is needed
We check first that sealant really is the fix. It won’t put right:
- Faulty frames rather than failed sealant
- Damage to finishes by other trades after we have sealed
- Frame gaps too wide for sealant, which the installer needs to correct
Not sure which it is? You can call the office on 01277 525 020 or email us and we’ll tell you honestly before you book.

Contractors’ notes for Sidlow
Sidlow lies roughly 21 miles out from central London. Towns within reach of London tend to keep building, from flats to offices and schools, and main contractors there need mastic that keeps to the programme. The South East is one of the drier parts of the UK. Winter mornings still bring frost and condensation on frames and panels, so external mastic is timed for workable conditions and agreed with the site manager.
For contractors at a school such as Dovers Green School, sealing has to be finished before term starts. Hospital estates such as East Surrey Hospital, 1.9 miles north-east of Sidlow, tend to grow and change in phases, often next to occupied wards, so facade and perimeter sealing has to fit the estates team’s plan. When units on a site such as Fontigarry Farm Business Park, 0.7 miles to the south of Sidlow, are refurbished or reclad, the panel joints and window perimeters are part of the mastic package.
Sidlow is about 2 miles south of Reigate, in Surrey. Sidlow sits inside our coverage and the rest of Surrey, and jobs here get the same fixed quote and 12-month guarantee as anywhere else.

What else we do in Sidlow
After the work
Problems stay small when the joints are checked regularly. Specifically:
- Brief the final clean team to avoid blades near sealant
- Share drawings and the specification as soon as possible
- Brief following trades on areas that have been sealed
- Allow flexibility for external sealing in damp or cold weather
Expect some settlement in the first months. Flexible sealants in the right joints handle normal movement. If that happens, let us know.
In wet areas, a weak sanitary joint shows up quickly once the building is occupied. Water gets behind trays, vanity tops and panels, and the repair falls into the defects period. Proper preparation, with the right silicone first time, keeps it off the defects list.
Doing it in-house
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.
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.
Commercial clients in Sidlow
Hospitality, education, healthcare, office and retail clients come to us directly as well. The work is planned around how the building runs, so guests, pupils, patients or staff are disturbed as little as possible.
Agents, factors and owners’ representatives all follow the same route: send the details, accept a fixed quote, and we carry out and guarantee the work. We can agree access arrangements and keyholder contacts beforehand.
