Moisture absorbed into brickwork and plasterwork causes them to expand slightly. When the brickwork and plasterwork dry they contract slightly. The water absorbed by the bricks and plasterwork usually causes a slight vertical crack at the edges of the internal window sills. The paint then starts to bubble along the vertical crack. This crack may continue around the length of the window sill before you notice it. What started out as a small vertical crack then becomes a horizontal crack along the bottom of the window sill on the interior face of the sill wall.
The cracks are usually not significant unless allowed to continue unabated.
Sometimes the moisture intrusion at sills are mistaken for rising damp! Water leaking in at the window sill may bypass the damp proof course (DPC) built in under the window sill as a water-resistant barrier. The moisture may then appear as bubbling paint or crazing cracking of plasterwork, or both, below the window, extending down to floor level.
On external face-brick walls, this may appear as efflorescence (a white powder).
Internally, this may appear as bubbling paint above the skirting or discolouration of the skirting itself.
How do you prevent the moisture intrusion into window sills?
My Comprehensive, Snag (New Home) and Maintenance Inspections include all of the above. Also included is the stand condition, property boundary and courtyard walls, swimming pools, garages, decks and so on. To clarify, an itemised list is provided below.
Your home inspection
Firstly, I am a trained and skilled InterNACHI Certified Home Inspector. Therefore, you will receive a thorough and professional, non-intrusive, visual home inspection and report of the property.
Moreover, I inspect the property you wish me to report on, inside and out, from the boundary walls to the top of the roof. Following that, I draw up a detailed comprehensive report of all the components inspected.
Outside the home, I will inspect the property boundary walls, the garden, the building’s walls and roof, driveway, deck etc. Moreover, if you request it I will inspect your swimming pool. Then I will move inside to inspect the walls, ceilings, floors, doors, and windows. In addition, I also inspect the heating, air-conditioning, plumbing, and electrical systems to ensure that they work as intended. Likewise, bathrooms, kitchens, and laundry rooms also receive a thorough check. Following on, I will check the roof (ceiling) space and basement, if any.
that, I will prepare a detailed home inspection report of all the items
inspected, including photographs. Furthermore, the report will be clear and
easy to read.
Moreover, as The Home Detective, I strive to ensure my home inspectionservices and reports are the best. I value customer service above everything else.
