About our mastic sealing in Howe Hill
For over 20 years we have resealed joints for owners, agents and landlords. Every applicator holds a CSCS card and we hold public liability insurance. Each building we complete carries a 12-month guarantee on our workmanship. We work on window and door perimeters on blocks, communal entrances and stairwells and external wall and movement joints, and the failures we’re asked to look at most are patchy repairs in mismatched sealant and brittle perimeter mastic across a building. For commercial sealant work in Howe Hill, you deal with one contact from quote to sign-off, whether it’s one building or several.
Rural conversions near places like Howe Hill often set modern frames into older stone, flint or brick. Perimeter mastic there has to grip an uneven face and suit the building’s character.
Our workmanship is guaranteed for 12 months, wherever the site is. If our installation lets you down in that time, we return and fix it.

Blocks and managed buildings in Howe Hill
Howe Hill lies roughly 39 miles out from central London. Within reach of London, blocks run by agents and associations are common around stations. Howe Hill sits in one of the drier corners of the country, the South East. Outside mastic still needs a dry joint and the right temperature, and the sunniest, most exposed sides of a building normally need attention first.
Property owners at sites such as Watlington Industrial Estate, 2 miles to the north-west of Howe Hill, can have mastic renewed between lettings. For a school such as Icknield Community College, perimeter mastic on windows and doors is a holiday job.
Howe Hill is about 9 miles south of Thame, in Oxfordshire. Businesses, contractors and managing agents in Howe Hill use us for work on mastic joints, as part of our coverage of Oxfordshire. We work across 423 places in Oxfordshire. For work in that direction, see our Reading page (12 miles or so).

Common problems we fix in Howe Hill
Buildings move with temperature and moisture, and every joint has to stretch and squeeze with them. A joint that was too narrow, too thin or the wrong product can’t cope long before it should.
Any of the following is a good reason to get the joints checked over:
- Damp patches beside frames
- Worn sealant at communal door frames
- Brittle perimeter mastic across a building
- Patchy repairs in mismatched sealant
With historic buildings such as Stonor Park (to the south-east of Howe Hill) in the wider area, owners of older properties around Howe Hill should expect mastic to need a product that suits old masonry.
What to look for in a quote
- What the guarantee covers, and for how long
- How joint depth will be controlled
- Can the work be phased to keep areas open?
- Is the sealant right for the movement and the substrate?
Why it’s worth doing now in Howe Hill
Open external joints let water into walls and around frames. Damp patches, stained plaster and decorating claims can follow, which is harder to deal with than resealing. One visit to deal with every failing joint makes more sense than several trips to a place like Howe Hill, rather than one at a time. Send photos of each area and we will quote for the lot.
Small jobs and large programmes are priced from the same things: what’s in scope, how we reach it, what’s specified and when it needs doing. Call for a quote, and you will have a fixed figure to work with.

Questions we are asked in Howe Hill
Is Howe Hill off your patch?
Not at all: smaller places are covered as well as towns. London and every South East county are within our area. We plan jobs in smaller places so return trips are kept to a minimum.
Do you take on block-wide or estate-wide mastic work in Howe Hill?
Yes. Portfolio-wide programmes are a regular request. We can phase the programme to suit your budgets and notice periods.
Do you work for managing agents and housing associations?
Yes, that’s exactly who this service is for. Buildings are scheduled in turn so you can plan around it.
Do you seal on top of existing sealant?
No. Failed sealant is removed and the faces cleaned back to sound, dry material first, because fresh silicone will not bond with aged silicone.
How many days will you need on site?
That varies with the scale of the job, but the work usually takes one or more days per building, depending on the joint lengths and the access. For bigger or phased jobs, we’ll set out a timescale with the quote.
Can you work to our specification?
Yes. The specification and the manufacturer’s installation guidance are what we work to, and we raise anything unclear before work begins.
Can you seal joints high up on a block?
We talk through access for each building when we quote. Tell us the number of storeys and whether scaffold or other access is planned and we’ll confirm the approach in the quote.
Commercial clients in Howe Hill
As a CHAS accredited contractor and Constructionline member, we make supplier vetting simple. We are fully insured, and our insurance certificate can go with the quote.
Hospitality, education, healthcare, office and retail clients book us directly too. The work is planned around how the building runs, so the building keeps working while we do.
What we can’t put right
Being straight saves everyone time. New sealant won’t cure:
- Failed window or door frames, which need a window contractor
- Substrate edges that need repairing first
- Old mastic suspected of containing asbestos, which must be tested and dealt with by a specialist first
If you’re not sure, just call the office on 01277 525 020 or use the quote form and we’ll give you a straight answer.
Joints and surfaces we work on
