Summertown: questions and answers
Will you plan work around the academic year at somewhere like University of Oxford?
Yes. Tell us the term dates, vacation periods and access windows, and we’ll plan the work around them. We are CHAS accredited and a Constructionline member, and paperwork such as RAMS is confirmed with the quote.
Would you work within a site like John Radcliffe Hospital?
Yes, healthcare and care buildings are part of our work. We follow the site’s permits, sign-in and infection-control procedures in every area.
What happens if old sealant might contain asbestos?
The duty to manage asbestos sits with the building’s dutyholder, so for older buildings we ask for the asbestos register first. If anything suspect turns up, we stop until it’s tested.
What does a mastic package typically include?
External perimeters and movement joints, internal caulking where specified, sanitary and kitchen joints, plus snagging, all priced as one package.
Can the building stay open while you work?
In the majority of cases, yes. Phased work can be planned so areas stay in use, with each area protected and signed.
Can you follow the specification on our project?
Yes. Include it with the drawings when you ask for a quote, and the quote will be based on it, flagging anything that needs clarifying.
How long does a typical visit take?
It depends on the scope, though a typical visit usually takes a day or two on a small fit-out and several weeks on a large multi-storey package. For bigger or phased jobs, we will set out a timescale with the quote.
Construction mastic for commercial buildings in Summertown
Mastic Doctor has been a subcontractor on construction projects for over 20 years. We price from drawings and the specification, agree the sequence with the site team and seal as areas are released. To price a package in Summertown, send drawings and the specification through our quote form. We work on brick and block movement joints, window and door perimeters and internal decorators’ caulk, and the usual reasons a site gets in touch are failed sealant in an existing building being refurbished and external joints sealed in damp or cold conditions that are now failing. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: on jobs in Summertown, preparation and product choice get the time they need.
In a smaller place such as Summertown, construction tends to mean small housing schemes, conversions and extensions to community buildings. Even a small site needs its perimeter and facade joints sized, backed and sealed properly.
The 12-month guarantee is for workmanship rather than wear and tear. How long a sealant joint lasts depends on movement, exposure, cleaning and use, so we are clear about what is covered before work starts.

What else we do in Summertown
From enquiry to sign-off
On arrival, we sign in, go through any site induction and check how permits are handled. Floors, finishes and fittings next to the joints are covered before anything is cut or cleaned, and the work usually takes a few days on a modest refurbishment and longer on multi-plot or multi-storey schemes. Several jobs near Summertown can be grouped on one trip. Mention the building’s opening times and we’ll work within them.
- First we look at the scope on site or from drawings.
- You receive a fixed quote covering scope, products and sequence.
- Site paperwork is confirmed and our CSCS-carded applicators are inducted.
- We seal plot by plot or floor by floor in line with the programme.
- Any frame gaps or issues outside our scope are flagged to the site team.
- The package is closed out, snags cleared and backed by our 12-month guarantee.
Before we start on site
- Point out any areas we must not close
- Make sure the joints can be reached
- Send asbestos survey details if the building is pre-2000

What we’re called out for in Summertown
Three-sided adhesion is a frequent fault on new work. Bonded to the base of the joint and both sides, sealant can’t stretch evenly so we set the depth properly before sealing.
Site and facilities staff are often the first to spot these:
- New external sealant already peeling away
- A mastic package split between trades with no clear owner
- Mastic snags holding up handover
- Existing joints on a refurb that need cutting out and resealing
Further education sites such as Oxford Sixth Form College, 1.8 miles south of Summertown, are extended and refurbished from time to time, with mastic often programmed into the summer break.
What your quote should include
- Whether primer will be used where the manufacturer specifies it
- The named product and why it was chosen
- How long is the guarantee, and what does it include?
- Health and safety accreditation such as CHAS
What sealant work can’t fix
Before quoting, we check that sealant is the right answer. It isn’t the answer for:
- Frame gaps too wide for sealant, which the installer needs to correct
- Deciding which fire-stopping product a penetration needs
- Glazing units that are cracked or misted
If you are not sure, just call the office on 01277 525 020 or send photos by email and we’ll give you a straight answer before you book.
Surfaces we seal
- Sanitary and kitchen joints
- Window and door perimeters
- Cladding and panel joints
- Brick and block movement joints
- Floor and skirting junctions
- Internal decorators’ caulk
Mastic packages on Summertown sites
At about 54 miles from central London, Summertown is within reach of the capital. Commuter-belt towns tend to see a steady flow of new flats, offices and commercial schemes, and each scheme needs its mastic sealed to programme. Summertown sits in one of the drier corners of the country, the South East. Winter mornings still bring frost and condensation on frames and panels, so external mastic is timed for workable conditions and agreed with the site manager.
When units on a site such as Jordan Hill Business Park (1.1 miles north of Summertown) are refurbished or reclad, the panel joints and window perimeters are part of the mastic package. Hotels like Galaxie Hotel, under half a mile to the south of Summertown, rarely close for long, so refurbishment mastic is phased floor by floor.
Summertown is about 2 miles north-west of Oxford, in Oxfordshire. Looking for construction mastic in Summertown? We can help. Summertown is one of 423 places we cover in Oxfordshire.
Anyone looking for construction mastic in OX2 and OX3 gets the same process as the rest of our area: details, then a fixed price, then sealing and a 12-month guarantee. Among the streets we cover are Islip Road, Hobson Road and Hernes Road. You’ll find Summertown on or near the A4165, so getting applicators and materials to site is simple. If your building is just outside Summertown, we cover North Oxford (1 mile south), Sunnymead (1 mile north), Cutteslowe (1 mile north), Park Town (1 mile south) and Norham Manor (1 mile south). Nearby towns on our patch include Didcot (12 miles south), Bicester (10 miles north-east), Abingdon-on-Thames (7 miles south), Witney (10 miles west), Carterton (14 miles west) and Thame (13 miles east).

Keeping the joints sound
Your facilities or cleaning team can help the joints last. Pass these on to them:
- Don’t schedule sealing before decorators and flooring are done
- Don’t force external sealing on a damp or frosty day
- Protect sealed areas from following trades
- Get the mastic subcontractor involved early in the programme
Our 12-month guarantee covers the workmanship from sign-off. The guarantee covers how we sealed, not later damage by other trades which is why protection after sealing matters.
In wet areas, a weak sanitary joint shows up quickly once the building is occupied. Water gets behind trays, vanity tops and panels, and the repair falls into the defects period. Proper preparation, with the right silicone first time, keeps it off the defects list.
How the quote is worked out
Each job is priced on its own details. The things that drive the figure:
- Specialist products, such as fire-rated or hygienic sealants
- The size and state of each joint
- Access and working height
- Whether old sealant has to be cut out first
We don’t publish prices, since every building and every scope is different. For a fixed figure, call for a quote and we’ll price your job on its own details.
Details that help us quote
There’s no need for a formal survey. These details are enough to start:
- A wide shot and a close-up of the area
- Whether an asbestos survey exists
- How the joints are reached, and at what height
- Any dates the work must fit around
Send details, get a quote, we seal, guaranteed: that’s how every job runs. To take the first step, call the office on 01277 525 020 or use the quote form.
