Construction mastic in Crondall
External mastic depends on the weather in a way most internal trades don’t. Each sealant has a temperature range, and damp, frost or condensation on frames stops work so it helps to sequence elevations with some flexibility. Internal sealing often fills those days. We work on sanitary and kitchen joints, floor and skirting junctions and window and door perimeters, and what we are called in for most is window and door perimeters that won’t pass inspection and different trades sealing to different standards. Whoever orders the work in Crondall, the brief is normally the same: a clear scope, tidy work and joints that don’t fail again.
Around smaller places like Crondall, building work usually means conversions of farm buildings, a few new houses or an extension to a hall or school. Perimeters, facade joints and internal sealant all need doing properly, however small the scheme.
Our 12-month guarantee is about workmanship, not wear and tear. Sealant wears with time, and movement, weather, cleaning and use decide how fast, so we’re clear about what is covered before work starts.

When to call us in Crondall
Value-engineered products sometimes end up in the wrong joints. A sealant that isn’t right for the substrate or the movement will fail ahead of time. We stick to the specified product, or put any alternative to you first.
Things that normally lead to an enquiry:
- Caulk cracking where joints are moving more than expected
- New external sealant already peeling away
- Perimeter gaps outside the sealant’s range
- Sanitary sealant damaged by following trades
For contractors refurbishing units at places like Fleet Business Park, 2.2 miles north-east of Crondall, the mastic covers cladding panels, roller-door and window perimeters.
Questions to ask before you book
- How the joint faces will be prepared and primed
- The terms of the workmanship guarantee
- How they’ll work around occupants
- What level of public liability insurance do they hold?

Why act early in Crondall
Refurbishments sometimes budget for new windows when the frames are sound and only the seal has failed. Sound frames often need only a new perimeter seal. We’ll say so if a frame itself is the problem. One visit to deal with every failing joint makes more sense than several trips to a place like Crondall, rather than one at a time. Send photographs of each area and we’ll quote for the lot.
Cost follows what’s involved: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a fixed quote and we will explain how it’s made up.

Your questions answered
Could you schedule work at a campus like University for the Creative Arts for the vacation?
Yes, holiday working periods are the norm on campus jobs. Let us know which documents your site asks for, and we’ll confirm them alongside the quote.
Can you take on a job at a hospital such as Spire Clare Park Hospital?
Yes, provided the work is planned with the site’s estates team. The estates team’s permit system and infection-control rules come first, and the work is planned around them.
What happens if the weather stops external sealing?
External sealant needs a dry joint and a temperature within the product’s range. Frosty or damp mornings can hold up external sealing so we normally switch to internal work when that happens.
How long before the joints can be used?
Curing time varies by product, and we confirm it on the day, and flag anything to keep off until it has cured.
Do you cover Crondall?
Yes. Crondall is in our area and the rest of Hampshire, within our coverage of Greater London, South East England and Scotland. For a quote, call 01277 525 020 or email us.
How much does the work cost?
It depends on the job: the volume of work, the access, the specified product and how it’s phased. Call for a quote.

Yes, with some planning. We agree a sequence with your contact so just one area at a time is disrupted.

Construction mastic around Crondall: how the place shapes the job

Using site staff can make sense for a small touch-up, but anything bigger is another matter: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.
