Knock-throughs & new openings in Stockport

Planning a knock-through in Stockport? We open up kitchens, dining rooms and through-lounges — engineered, signed off and left ready for plaster.

From Bramhall and Cheadle Hulme semis to stone terraces in Marple and Romiley, Stockport work ranges from single doorway openings to full through-lounges with twin beams.

A knock-through joins two rooms into one — most often the kitchen and dining room, or the front and back rooms of a terrace or semi. We also form new doorways and widen existing openings, including large openings in rear walls for bifold or sliding doors.

Knock-throughs & new openings in Stockport: your questions answered

Do you cover Stockport?

Yes — Stockport and the surrounding area are part of our regular patch. Stockport structural work is inspected by Stockport Council building control or a registered approver.

Do I need planning permission for a knock-through?

Usually not for internal walls in a house. You do need Building Regulations approval if the wall is load-bearing, and listed building consent if the property is listed.

Can you form an opening for bifold doors?

Yes. We install the steel lintel or goalpost frame the engineer specifies and leave the structural opening sized to your door supplier's dimensions.

Will a knock-through make a lot of dust?

Cutting masonry is dusty, so the work area is sheeted off, dust extraction is used on cutting tools and the site is cleaned at the end of each day.
