- 111How to handle a bad contractor who won't fix poor workPaying before inspecting leaves homeowners with little leverage when contractors deliver subpar or unauthorized work. Without a clear path to recourse or refunds for shoddy repairs, people are left feeling cheated and stuck with expensive, unsightly results.
- 52How to tell if roof flashing is installed wrongPoorly installed roof flashing relies heavily on caulk rather than proper metal integration, leaving homeowners with leaks and visually unacceptable work. Without clear industry standards to reference, it becomes difficult to dispute substandard craftsmanship and demand corrections from a roofing contractor.
- 48Water keeps getting in the house during heavy rainHeavy rain overwhelms existing doors, garage thresholds, and drains, allowing water to pool inside the living spaces and garage. This sudden flooding forces residents to constantly manage overflowing entry points and deal with moisture damage from structural vulnerabilities.
- 46Why does my new plumbing still have bad water pressure and risky joints?Poorly installed pipes and high-tension fittings put excessive pressure on joints, creating constant risks of leaks and floods. Even after professional upgrades like Pex, substandard workmanship leaves homeowners dealing with weak water flow and questionable setups like S-traps that require tearing out walls and digging up pipes just to check for defects.
- 39How to tile over an uneven subfloor without tearing it upAn uneven subfloor makes tiles crack and shift if they are laid without a flat surface. Fixing low spots with a feather finish patch or self-leveling compound avoids tearing out the old plywood or linoleum entirely.
- 29How to fix previous owner DIY nightmaresPrevious homeowners often disguise shoddy work with surface-level cosmetic updates that hide hazardous and poorly executed projects. Uncovering these hidden defects week after week leaves new buyers feeling like their house is held together entirely by caulk, making it impossible to trust the home's fundamental safety.
- 27How to tell if home repair work is actually badSubstandard workmanship shows up as messy wiring, exposed unterminated copper ends, uneven flooring transitions, and dips or humps across newly installed surfaces. Spotting these flaws during a final walkthrough makes it difficult to decide whether to withhold final payment or accept the installation as is.
- 24How to find hidden home defects after buyingStandard general home inspectors routinely miss major issues like uninstalled roof components, faulty electrical work, and plumbing failures. Relying on them leaves buyers facing massive, unexpected repair projects and damages after they have already moved in.
- 14How to spot hidden installation errors before paying for a new roofCatching minor mistakes like missed nails or improper flashing early is critical because visible flaws usually indicate deeper, hidden installation failures elsewhere. Without catching these issues before final payment, homeowners are left dealing with chemical incompatibilities, leaks, and costly repairs that the original crew should have fixed.
- 13How to clean mold on drywall or know when to cut it outSurface sprays only treat top-layer growth, leaving hidden spores inside soaked walls to spread further. Trying to guess whether to patch or cut out the drywall stops people from stopping the damage before it ruins the structure.
- 10Water leaking from roof corners and sidewallsImproper shingle overlapping and flashing near corners cause water to wick sideways or get trapped under the upper layers instead of flowing downward. This leads to chronic water intrusion and rotted roof decking during heavy rain.
- 9How to replace a shower drain cover with a broken screw holeWhen a shower drain cover's mounting screw hole is broken, standard installation methods fail and leave the cover loose. This forces people to resort to makeshift fixes like holding it down manually, preventing a secure and permanent repair without proper alternative securing techniques.
- 7Water leaking behind new gutters and soffitsWater is following the drip-edge flange downward, hitting the back of the gutter, and dropping straight down the outside instead of flowing inside. This accumulated water collects between the soffit and the lip of the fascia, causing leaks that did not happen before the installation.
- 5How to tell if a ridge vent was installed correctlyRoofers sometimes install ridge vents just for appearance without cutting the roof decking underneath, but standard visual checks or endoscope cameras can fail to confirm the cutout. Without knowing if the gap or missing shingle near the end is a defect or normal, homeowners are left guessing whether they need to pay for repairs.
- 5Why is my new house roof made with cheap materials and visible beams?Homeowners discover structural beams poking through their roofs, cheap three-tab shingles, and chipboard instead of plywood sheathing on newly built houses. These severe defects cause immediate worry about whether the construction is a professional job and whether the roof needs to be repaired or fixed.
- 4Why is the plywood roof decking sagging on my new house?Premature sagging and warping on new roof decking is typically caused by trapped moisture due to poor attic ventilation. This excessive humidity compromises the structural integrity of the plywood, leading to noticeable dips between the roof rafters.
- 4Are drywall cracks in an older house normal settling or structural damage?Older homes naturally shift and settle over time, but previously painted-over cracks resurfacing around doorframes often leave buyers wondering if they purchased a defective house. This uncertainty makes it difficult to know whether to simply patch the gaps with standard DIY materials or hire a professional to check for serious structural defects.
- 3Stair bullnose flexing and separating from treadThere is zero physical support under the bullnose pieces, leaving a gap between the bullnose and the tread. This causes the pieces to flex under normal weight and pull apart. Even when installed with screws and the recommended PL adhesive in new construction, these glue-down products fail to hold.
- 3Exposed wood corner where new and old roof meetMissing flashing or caulking where a roof addition meets an older section leaves wood exposed to potential water accumulation and dry rot over time. Because this spot is hidden from the ground, it often goes unnoticed until someone is on a ladder or the roof, raising concerns about long-term damage.
- 2Sharp carpet tack strips poking through the floorCarpet tack strips are poking through the carpet around room perimeters and doorways, jabbing people in the feet and even causing bleeding. This hazard makes walking barefoot near edges painful and forces homeowners to tear up the carpet to find and fix the exposed sharp points.
