Mastic sealing near Preston
Share the site address and what’s failing, and we’ll reply with a fixed quote or arrange a visit.
On site: what to expect
Working in a building that stays open takes some planning. We sign and contain the area we are in, keep walkways clear and work section by section so the rest of the building stays in use. In Preston, most buildings stay in use during the work, so zones and timings are agreed with whoever manages the building. Areas are handed back as each section is finished.
- First we look at the mastic on each building and note what needs replacing.
- A fixed quote follows, split by block or building if that suits you.
- Dates, areas and access are agreed so residents or tenants can be told in advance.
- Old sealant is stripped and each face prepared back to firm material.
- Backing rod and primer go in where the joint and the product need them, then new sealant is applied and tooled.
- Completed joints are inspected and carry a 12-month workmanship guarantee.
Before we start on site
- Send any specification or drawings in advance
- Share your working hours and any access restrictions
- Move anything stored against the joints

Mastic sealing in Preston
Our clients include managing agents, property factors in Scotland, housing associations and landlords with block or commercial portfolios. A planned, building-by-building programme often works better than reacting to each complaint and we quote and schedule each building in turn. If you’re dealing with brittle perimeter mastic across a building and water getting in round frames after rain, we can help. Most enquiries from Preston start with one failed joint and grow into a wider look at the building: we check the joints around it and give you an honest view of what needs doing now and what can wait.
For managing agents in Preston, resident access, notice periods and the building’s rules shape the job. We work to the agent’s notice and access plan, so residents know what’s happening.
Work we carry out comes with a 12-month guarantee. If an installation problem shows up, phone 01277 525 020 or use the quote form and we will arrange a return visit.

What we’re called out for in Preston
Previous repairs often sealed new mastic over old. New silicone has nothing to grip on old silicone, so these repairs rarely last.
Look out for the following:
- Estate-wide sealant that is simply worn out
- Draught complaints from residents or tenants
- Failed external movement joints
- Worn sealant at communal door frames
Student accommodation around universities such as Westminster University (to the west of Preston) is normally managed block by block, which suits a planned mastic programme.
Questions to ask before you book
- Will failed sealant be removed rather than covered?
- Will RAMS and insurance details be available?
- Proof of insurance
- How they’ll work around occupants
General trades versus a specialist
Certain joints really need a specialist: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. A poor seal in places like these tends to cost more to put right later.
The visible bead is only part of the job. Backing rod, primer where specified and a joint designed to move with the building are where general trades tend to cut corners.

Your questions answered
Do you work in London buildings with loading restrictions?
Yes. Inductions, permits and timed loading are routine for us in London. The building manager’s rules go straight into our method. All of Greater London is inside the ULEZ, and our planning allows for it
Will you take on work at estates like East Lane Business Park, close to Preston?
Yes. We cover Preston and the area around it, including industrial estates, business parks and retail parks such as East Lane Business Park. Send details of the unit and the work through our quote form for a quick quote.
Who decides which product is used?
The specification comes first, if there is one. If there isn’t one, it comes down to the joint: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.
Can you plan resealing across several buildings?
Block-wide and estate programmes are common. The quote can be split however suits your budgeting.
Do you guarantee the mastic work?
Our workmanship carries a 12-month guarantee and we hold public liability insurance.
How long do sealant joints last?
Nobody can honestly give a figure in years, since movement, weather, cleaning and use all affect it. Regular checks let you plan resealing before leaks or damage.
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 will confirm the curing time on the day.
