Mastic sealing in Speedwell, done properly
Managing agents and housing associations normally need paperwork before anyone starts. For documents, tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we’ll confirm with the quote. We are CHAS accredited and a Constructionline member, with public liability insurance. If you have patchy repairs in mismatched sealant and the same joint failures repeated across a portfolio, we can put it right, on communal kitchens and washrooms, external wall and movement joints and shopfronts below residential blocks alike. Looking for mastic applicators who cover Speedwell? We’ve been sealing commercial buildings since 2005.
Around smaller places like Speedwell, older walls fitted with newer windows are a familiar sight. Perimeter mastic there has to grip an uneven face and suit the building’s character.
Work we carry out comes with a 12-month guarantee. Should something we installed fail, call the office on 01277 525 020 or email us and we will come back to it.

When it isn’t the sealant
Part of a good diagnosis is knowing where sealant stops. We will tell you if the real problem is one of these:
- Leaks from above rather than through a joint
- Cracked or crumbling render, brick or stone at the joint edges (we will tell you if so)
- Misted or failed double-glazed units
Not sure which it is? You can give us a call on 01277 525 020 or email us and we’ll tell you honestly before you book.

Planned mastic for Speedwell portfolios
Speedwell is in the South East, one of the UK’s drier regions. Outside mastic still needs a dry joint and the right temperature, while the elevations that take the most sun tend to show hardened mastic first. Speedwell is about 40 miles from central London. Within reach of London, blocks run by agents and associations are common around stations; their frame mastic often ages block-wide.
Schools and community buildings such as Woburn Lower School need frame and external mastic kept sound like any building. If you look after a block within reach of Aspley Guise station, 2.9 miles to the north of Speedwell, frame and balcony mastic can be renewed on one programme. With historic buildings such as Woburn Abbey, 0.7 miles to the east of Speedwell, in the wider area, owners of older properties around Speedwell should expect mastic to need a product that suits old masonry.

What the job involves on each surface
Estate-wide resealing programmes
Consistent products and colours across an estate make future maintenance simpler and easier to manage.
Tenement and older buildings
Older buildings, including Scotland’s sandstone tenements, have their own joint details. The material either side of the joint shapes the product choice.
Should maintenance staff do it?
Site maintenance staff can often handle a short internal joint. The usual problems come from preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.
What you see is the finished bead, but most of the work is hidden. Backing rod, primer where specified and a joint designed to move with the building are where general trades tend to cut corners.
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 occupiers notice. Halls, stores and units around places like Speedwell may not be checked every day, so a failed joint can leak for a while before anyone sees it. Renewing joints in good time avoids the problem.
The product called for affects the cost, and so does the preparation, such as cutting out, priming or new backing rod. Access, phasing and site requirements come into it too.

Your questions answered
Do you take on block-wide or estate-wide mastic work in Speedwell?
Yes. Planned programmes across a building, block or estate are a core part of this service. We can phase the programme to suit your budgets and notice periods.
Is Speedwell too small for you to travel to?
Not at all. Speedwell is within our area. London and every South East county are within our area. We plan jobs in smaller places so return trips are kept to a minimum.
Will you just go over the old sealant?
No. We cut the old material out and clean the joint back before sealing, because fresh silicone will not bond with aged silicone.
Is mastic sealing guaranteed?
There is a 12-month guarantee on our workmanship, backed by public liability insurance.
Can people stay in the building while you reseal?
The work is planned around occupiers. We agree the programme so you can notify occupiers, and entrances stay in use.
Can you seal joints high up on a block?
We talk through access for each building when we quote. Tell us the building height and any access already in place and we’ll confirm the approach in the quote.
How long does a job like this take?
That varies with the scale of the job, though a typical visit usually takes a day or two for a single block, longer for an estate programme. For bigger or phased jobs, we will set out a timescale with the quote.
