How we handle mastic sealing in Rowstock
For over 20 years we have resealed joints for owners, agents and landlords. Every applicator holds a CSCS card, and the work is backed by public liability insurance. Resealed mastic joints in Rowstock carry our 12-month guarantee. Site teams most often ask us about estate-wide sealant that is simply worn out and draughts at frames across a block, on shopfronts below residential blocks, communal entrances and stairwells and external wall and movement joints. Most enquiries from Rowstock 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 buildings around smaller places like Rowstock, we group work so one trip covers it. Send photos of the frames and joints and we’ll give a fixed quote.
What our 12-month guarantee covers is the way we did the job: the preparation, the sealing and the tooling. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

Cost factors for mastic joints
Before we quote, we look at:
- How much existing material needs removing
- Distance, for remote addresses
- Joint width, depth and condition
- Which sealant the job calls for
The price depends on the quantity of joints, what has to come out first and the access. Call for a quote when you’re ready.
Details that help us quote
Diagnosis starts before we arrive. Tell us:
- Where the site is, with the postcode

From enquiry to sign-off
When we get to site, we report to your site contact and complete whatever induction the building runs. Everything around the joints gets protected before any cutting starts, and the work typically takes one or more days per building, depending on the joint lengths and the access. For work around Rowstock, we aim to finish in one visit, so photographs and measurements up front really help. That way the right products come on the day.

Advice
Owners, agents and contractors
Housing associations and managing agents often need work done across blocks and communal areas. We phase the work so people keep access, and each stage is agreed with your contact.
If you look after buildings for someone else, you need clear quotes and clear reporting. We quote a fixed sum, confirm the scope and walk the finished work with you or your representative, plus a 12-month guarantee.

Questions we’re asked in Rowstock
Do you work for managing agents with blocks near Didcot Parkway station?
Yes. Blocks of any size are within what we do. We work to your notice and access arrangements.
Is Rowstock off your patch?
Not at all. Rowstock is within our area. London and every South East county are within our area. Good photographs up front let us bring everything on the first visit.
Do you work with property factors and landlords?
We do. Most of our mastic sealing is for agents, factors, housing associations and portfolio landlords, and we quote building by building or as a programme.
How many days will you need on site?
It depends on the scope, though a typical visit usually takes a few days for most blocks, with larger programmes scheduled building by building. For bigger or phased jobs, we’ll set out a timescale with the quote.
Can you send RAMS and CSCS details before starting?
Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we will confirm with the quote. We are CHAS accredited and a Constructionline member.
Will you just go over the old sealant?
No. We cut the old material out and clean the joint back before sealing, since fresh sealant will not bond reliably to aged material.
Is mastic sealing guaranteed?
Every building we reseal has a 12-month guarantee. It applies to our workmanship rather than damage or problems with the frames.
What happens if it’s left?
Replacing mastic before water gets in is a planned job. Once water has tracked in, the repair list grows, and the complaints come with it. Around Rowstock, it’s better to renew all the failing joints at once. Photos of every joint help us quote for the whole job.
The specified product makes a difference, and so does the preparation, from cutting out to priming and backing rod. Access, phasing and site requirements come into it too.

Blocks and managed buildings in Rowstock
Three care or nursing homes sit less than 2 miles from Rowstock. Owners of care premises can bring window and door mastic into a phased programme planned around the home. Rowstock is in the South East, one of the UK’s drier regions. Even so, frame mastic only goes on in dry, workable conditions, and elevations facing the sun and the prevailing weather are usually where frame mastic ages first.
Blocks of flats and mixed-use buildings often cluster around stations such as Didcot Parkway station (3 miles east of Rowstock) and their window and balcony mastic tends to age at the same rate across a building. For owners of several units at places like The Core Business Centre, 1 mile north of Rowstock, one programme can deal with frame and external mastic across the lot. Older community buildings, Church of St Matthew among them, often have frames of mixed ages whose mastic varies.

When to bring in a specialist
Site maintenance staff can often handle a short internal joint. Where it goes wrong is preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.
Redoing a failed joint usually costs more than getting it right at the outset, 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.
