How we handle mastic sealing in Lye Green
Treatment starts with a proper look: which joints have failed, why, and whether sealant is the right answer. Failed mastic is stripped, the faces taken back to sound material, primed where the manufacturer specifies and resealed, with backing rod setting the depth where it’s needed. Site teams most often ask us about the same joint failures repeated across a portfolio and patchy repairs in mismatched sealant, on shopfronts below residential blocks, communal kitchens and washrooms and balcony and threshold joints. Whoever orders the work in Lye Green, the brief is typically the same: a fixed quote, no surprises on site and a 12-month guarantee behind the result.
For owners with a single building near Lye Green, we plan to finish in one visit where possible. Photos of each elevation help us quote accurately.
Building owners and contractors get the same cover: a 12-month guarantee on our workmanship. It doesn’t extend to damage, faults in the building or work by others, and we are upfront about that.

Common questions from Lye Green clients
We manage a building near Berkhamsted station. Can you help?
Yes. Blocks of any size are within what we do. We work to your notice and access arrangements.
Is Lye Green off your patch?
No. Small places get the same service as large ones. London and every South East county are within our area. Good photographs up front let us bring everything on the first visit.
Do you do block-wide mastic programmes?
Yes, planned programmes suit estates and portfolios. The quote can be split however suits your budgeting.
Is it fine to apply new sealant on top of old?
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 long before the joints can be used?
That comes down to the sealant and the temperature. Some products skin over quickly but need longer to cure fully, so we’ll confirm the curing time on the day.
What guarantee do you give on resealing?
There is a 12-month guarantee on our workmanship and we hold public liability insurance.
Do you work to architects’ specifications?
Yes. We follow the specification, along with the manufacturer’s installation guidance, and we raise anything unclear before work begins.
Maintenance after handover
For the best life from the joints:
- Reduce knocks to communal area joints
- Look at the sunniest and most exposed elevations first
- Check the asbestos register before any old mastic is disturbed
- Make mastic part of routine maintenance checks
Log the date and extent of the resealing for each block. It helps plan the next round and gives you a history.
The longer failed joints are left, the more likely the substrate edges break up. Then the edges may need repairing first.

Owners, agents and contractors
Hotels, schools, healthcare sites, offices and retail units come to us directly as well. We plan around the way the building is used, so guests, pupils, patients or staff are disturbed as little as possible.
For main contractors, we work as the sealant subcontractor, on new build and refurbishment alike. Programme, specification and site rules come first.
How the job changes by surface
Tenement and older buildings
Older buildings, including Scotland’s sandstone tenements, have their own joint details. We look at the substrate before choosing a sealant.
Planned maintenance
Resealing can be scheduled alongside other planned works, building by building.
Planned mastic for Lye Green portfolios
Central London is about 26 miles from Lye Green. Commuter-belt towns tend to have plenty of managed blocks near stations and town centres; their frame mastic often ages block-wide. Lye Green is in the South East, one of the UK’s drier regions. Outside mastic still needs a dry joint and the right temperature, and elevations facing the sun and the prevailing weather are typically where frame mastic ages first.
If your remit includes a building such as Brushwood Junior School, frame and door mastic can be programmed for the holidays. For owners of several units at places like Waterside Business Park, 1.8 miles to the south-west of Lye Green, one programme can deal with frame and external mastic across the lot. Trustees of buildings like St George's Church can bring frame and external mastic into a planned maintenance list.

Cost factors for mastic joints
Sealant work doesn’t have a standard rate, since sites vary so much. What we look at:
- Removal of failed or old sealant
- The product specified
- Joint width, depth and condition
- Distance, for remote addresses
Access can matter as much as the joints themselves: easy-to-reach joints are quicker than those that need equipment to get to. Tell us how the joints are reached and call for a quote.
Sending details for a quote
Diagnosis starts before we arrive. Let us know:
- Asbestos survey details if the building is older
- Access details, including height
- Whether the building will be occupied during the work
- Drawings or a marked-up plan, if available
To get a fixed quote, speak to us on 01277 525 020 or email us. You can also send details through our quote form.
When to bring in a specialist
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.
General builders and handymen seal joints, but it isn’t their main trade. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint, which is what makes a joint last.
Diagnose, treat, sign off
We follow your site rules from the start: sign-in, induction and whatever permit system the building uses. With the paperwork done, the joints are worked through in the order agreed with your site contact. Smaller jobs around Lye Green can be grouped with others nearby, which keeps travel down.
