Heath plastering and rendering repairs outside render on Southampton houses, replacing cracked and loose sand and cement so the wall sheds rain again. ## Price of a Southampton render repair The price pays for sounding the coat, cutting out the failure, and laying sand and cement flush with the coat that stayed. A larger failed area moves the price up. A higher patch moves the price up because it needs a scaffold tower. A scaffold tower is a temporary stand of boards. Whether the brick or block under the coat is still firm also moves the price. A few open cracks are a different job from a broad hollow area that has to come off. - External rendering repair: from £350 - A bead and a rebuilt corner are included where the failure crosses a corner or the side of a window opening. - The scaffold tower is included when the failed coat cannot be reached from the ground. - Colour after the new coat has hardened is separate. Mending a gutter, the roof covering or a window that sent rain in behind the face is its own job. - Coating all of the outside walls is a separate price for rendering the house. We are on time. The price set for this wall stays as set. ## External rendering repair across Southampton We serve Southampton from our base in Winchester. - Shirley - Portswood - Bitterne - Woolston - SO14 - SO15 - SO16 - SO17 - SO18 - SO19 ## What happens on the day On the day the failed outside coat is replaced with sand and cement. We sound the coat first. We cut out what has failed. We build the new coat up to the coat that still grips. Sounding means knocking the coat to find where it has left the wall. Render means sand and cement spread on an outside wall. ### Reaching failed coat on the house Where the failed coat sits too high to work from the ground, we stand a scaffold tower before any knocking. A scaffold tower is a temporary stand of boards. We sheet the windows, the doors and the paving under the patch. A patch we can reach from the ground does not need the tower. ### Hollow notes in the outside coat We knock the outside coat from one side of the damaged area to the other. A hollow note means blown render, coat that has pulled away from the brick or block while the face still looks solid. We chalk every hollow note. We rake open a crack that still holds and clear the dust, which keeps rain from tracking through that crack. ### Bare wall ready for new coat We hack off only the chalked coat. We stop the cut as soon as the surrounding coat still holds onto the wall. We sweep the dust from the bare face. We then wet that face, because a wet face lets the new sand and cement bond. ### Sand and cement built back in layers On a deep opening we drag a comb through the first sand and cement while it is soft. That combed layer is a scratch coat. The lines let the next layer lock on. We then draw a long straight edge over each layer until the build sits level with the coat left in place. Where the old coat is smooth, we rub the last layer shut with a float. A float is a flat tool. Where the old coat is rough, we press that same roughness into the wet face. ### Corners, beads and the ground line We build a damaged corner back so its line runs straight. We rebuild the side of a broken window opening in the same way. We rebuild the side of a door opening in the same way. Before the face layer, we bed a bead onto the corner. A bead is a thin metal angle that holds the corner straight. We stop the fresh face in a straight line just above the ground. The tower, if we used one, comes down after that line is finished. ## Southampton render repair questions ### Do you repair cracked and loose render on a house in Southampton?
