GS Renovation carries out structural alterations throughout Romford, whether that is a new opening in an interwar semi near Hornchurch Country Park or replacement joists in a generous 1930s suburban home in RM1. With 30+ years across Havering, we handle new openings, supported beams, replacement joists and underpinning to a proper engineered standard.
New openings and supported beams in Romford
Romford's interwar houses sit on good plots, which makes them ideal for rear openings into extensions, wider doorways through the solid spine wall, or a supported opening between kitchen and dining room. Every one of these is a structural change to load-bearing brickwork, so we begin with a structural engineer who calculates the steel beam and the padstones needed at each bearing.
On site we prop the structure above, form the opening in staged cuts, and set the beam onto its padstones before the temporary supports come out. Because many of these 1930s homes have suspended timber ground floors, we also check the joists and wall plates as we go, replacing any that have softened over ninety years of service.
Underpinning and joists in Havering's interwar homes
Some Romford properties near mature trees around Raphael Park sit on shrinkable London clay, and seasonal movement can leave older foundations needing underpinning. Where an engineer confirms it, we underpin in the traditional sequenced bays, working under building control inspection so the new foundations are recorded and signed off under the Building Regulations rather than treated as cosmetic patching.
Replacement joists are common in these interwar homes too, whether from historic leaks or notching by earlier trades. We size new joists to the span, provide proper end bearings and restraint, and coordinate with Havering building control throughout. None of this needs planning permission unless the home is listed; it is building control that certifies the structural work.
