The structural carpentry hidden behind your walls, floors, and ceilings rarely crosses your mind—until something goes wrong. First fix carpentry forms the skeleton of your home, and when it begins to fail, the consequences can range from annoying squeaks to serious safety concerns. Fortunately, your home usually gives you plenty of warning signs before problems become critical. Here are five telltale indicators that your first fix carpentry needs professional attention.
1. Bouncy or Uneven Floors
What You'll Notice: Walking across your floor feels springy, or you notice a noticeable dip or slope in certain areas. Furniture may no longer sit level, and you might hear creaking with every step.
What's Happening: Floor joists—the horizontal beams supporting your flooring—may be undersized, improperly spaced, damaged by moisture, or suffering from structural movement. In older properties, rot or insect damage can compromise joist integrity.
What To Do: Bouncy floors rarely improve on their own and typically worsen over time. A professional carpenter can assess whether joists need reinforcing, replacing, or additional support adding. This isn't a DIY fix—improper repairs can create bigger structural issues.
2. Sagging or Uneven Rooflines
What You'll Notice: Looking at your home from outside, the roofline appears to dip or sag rather than forming a straight line. From inside the loft, you might see bowing timbers or gaps where roof members should meet.
What's Happening: Roof structures bear enormous weight and constant stress from wind and weather. Sagging indicates that roof trusses, rafters, or ridge beams are failing—potentially due to under sizing, rot, previous poor-quality repairs, or structural movement.
What To Do: Roof structural issues require immediate professional assessment. Even minor sagging can indicate serious problems that worsen rapidly, particularly during heavy rain or snow. A qualified carpenter can determine whether repairs, reinforcement, or replacement is necessary before the issue affects your home's weatherproofing or safety.
3. Cracks Around Door Frames and Windows
What You'll Notice: Cracks appearing in plaster or paintwork around door frames and window openings, doors that suddenly stick or won't close properly, or gaps appearing between frames and walls.
What's Happening: Door and window frames installed during first fix carpentry are fixed to the structural timbers. When these timbers move, shift, or deteriorate, frames move with them, causing visible cracks and operational issues. This often indicates problems with the surrounding stud work or structural frame.
What To Do: While some settlement is normal in new builds, cracks in established properties suggest ongoing structural movement. Simply filling cracks treats symptoms, not causes. A carpenter can identify whether the underlying stud walls or structural timbers need attention.
4. Visible Bowing in Walls
What You'll Notice: Interior walls appear to curve outward, particularly noticeable when looking along the wall from an angle. You might struggle to fit furniture flush against walls, or notice gaps behind skirting boards.
What's Happening: Stud walls—the timber frames behind plasterboard—should be straight and properly braced. Bowing indicates studs installed incorrectly, lacking proper spacing or bracing, or suffering from moisture damage. In load-bearing walls, this can indicate serious structural concerns.
What To Do: Bowed walls affect both aesthetics and potentially your home's structural integrity. Professional assessment determines whether walls need rebuilding, additional bracing, or if there's an underlying moisture issue causing timber movement.
5. Unexplained Squeaks and Movement
What You'll Notice: New or worsening squeaks when walking on floors or stairs, or a general sense that parts of your home feel less solid than they once did.
What's Happening: Squeaks occur when timber components rub against each other or fixings, indicating movement where there should be rigid connections. This suggests failing fixings, timber shrinkage, or structural components working loose over time.
What To Do: While annoying, squeaks indicate something isn't structurally sound. A carpenter can identify whether the issue stems from floor joists, staircase construction, or other first fix elements, and implement proper solutions rather than temporary fixes.
