About our bi-fold & sliding door openings service in Auchterarder
We cover bi-fold & sliding door openings in Auchterarder (PH3, PH4) and the streets around it. Our coverage runs across Perth and Kinross, so nearby villages are included too. Each job is designed by a structural engineer and approved through Perth and Kinross Council before work begins.
We coordinate the structure with your door supplier's sizes, so the finished opening matches the frame. The survey visit, structural calculations from a qualified engineer, building standards, propping, steel, cavity trays, weather protection while the wall is open and making good are all covered in one itemised written quote.
What to expect
- New brickwork at the reveals and above the opening should match the existing in colour, size and bond. Sound bricks from the wall being removed are often cleaned and reused, and the mortar colour is matched as closely as possible.
- Very wide openings, or ones that run close to the corner of the house, may leave too little wall for the beam to bear on. In that case the engineer may specify steel columns or a goalpost frame standing on its own foundations.
- Door suppliers quote a structural opening size, which allows for the frame and fixing tolerances. Agreeing that size before the steel is designed avoids reveals that are too tight or gaps that have to be packed out later.
- Both leaves of a cavity wall need support over the opening. Depending on the design, the outer brickwork may sit on a plate fixed to the beam or on a separate external lintel, and the engineer specifies which suits the loads and the look.
- Width, what sits above, whether columns or a goalpost are needed, outer leaf support, threshold works and how much brickwork needs matching all affect the price. The doors themselves are normally supplied separately unless agreed otherwise.
What happens, step by step
Survey in Auchterarder
We visit, look at the wall and what sits above it, measure the opening and note services, access and how the steel can be brought in.
Engineer's design
A structural engineer sizes the beam, padstones and any posts, and sets out the temporary support needed while the wall is out.
Building warrant
A building warrant is applied for from Perth and Kinross Council, and work starts only once the warrant has been granted.
Install and sign-off
Props go in, the opening is formed, the steel is set and packed, building standards inspects it, and we make good.

Approvals in Auchterarder
Steel beam work in Auchterarder needs a building warrant from Perth and Kinross Council. The structural design is part of the application, and the council's building standards team accepts the completion certificate once the work is done as approved.
Scotland has no Party Wall Act. Work affecting a shared wall is governed by your title deeds and the general law, and in flats by the Tenements (Scotland) Act 2004, so it is sensible to agree the work with neighbours in writing before starting.
Bi-fold & sliding door openings in Auchterarder: your questions
Do I need a party wall agreement for bi-fold & sliding door openings in Auchterarder?
There is no Party Wall Act in Scotland. Your title deeds and the general law apply instead, and the Tenements (Scotland) Act 2004 for flats, so agree the work with your neighbour in writing before it starts.
Can I stay at home while the work is done in Auchterarder?
Usually, yes. The work area is screened and floors are protected. The rooms either side of the opening are out of action for a few days, and there is some noise and dust while the masonry comes out.
Do I need building regulations for bi-fold doors?
Yes, when you are making a new or wider opening in an external wall, because that is structural work. Building standards also checks the doors meet energy efficiency and safety glazing requirements. In Scotland a building warrant is needed before the work starts. Replacing doors like for like in an existing opening is different and is often handled through an installer's competent person scheme.
Should I order my doors before the opening is made?
It helps to choose them first. The supplier's structural opening size and threshold detail feed into the steel design, so the opening is formed to suit the doors exactly. Many people order once the engineer has confirmed the opening, then time the structural work so the gap is weathered for as short a time as possible.
Will the house be open to the weather while the wall is out?
Only briefly, and it is protected throughout. Once the wall is out, the opening is sheeted or boarded so it stays weathertight and secure until the doors arrive. Timing the structural work close to the door delivery date keeps that period as short as possible.
Do you also work near Auchterarder?
Yes. We also cover nearby towns including Crieff, Tillicoultry, Alva and Dunblane.
