Enlarging the Opening

Filed Under: DIY Outdoor, Do it yourself, Remodeling    by: ITC

Having set the new lintel in place and re-finished the brickwork of the inner leaf above it, you can cut out the brickwork at the sides of the opening and, if necessary, across the base. First, draw the outline of the new opening on both sides of the wall, making it about lin wider and deeper than the actual frame dimensions to give a fitting tolerance.

External walls comprise two layers of bricks; each layer should be treated separately, working in from each side of the wall.

If the wall is a solid one produce a square edge along the opening outline on the inner layer by cutting through bricks where necessary. Always remove complete bricks even if they project beyond the outline. This gives a toothed effect to the edge.

If the base outline runs through the center of a course of bricks, remove the course completely; you can make up the difference later.

Replace the outer layer at the sides of the opening by mortaring cut bricks into the toothed sections so that their cut ends are innermost.

Next, replace the area of wall above the window, laying the bricks on the lintel and copying the original brickwork bond for strength and appearance. In a solid wall, you can create a curved, self-supporting soldier arch by setting a wooden framework in the opening on which the bricks of the arch are laid. Then the surrounding courses are fitted round the arch and the mortar left to set for a couple of days before removal of the formwork.

The frame must sit squarely in the opening; if it is twisted, you may have problems in opening and closing the window and the glass will be under stress and may shatter at the slightest vibration.

In a solid wall you can set the frame: flush with the outer face with its sill overhanging the edge; in the center of the opening with narrow reveals on each side; or flush with the inner face with a sub-sill at the bottom to throw water clear of the wall.

When the frame is set forward in the opening, the sides and top of the reveal are plastered and a wooden or tiled window board set across the bottom. When set at the back, it is normal to trim around the inside of the frame with molding

The simplest method of securing the frame is with frame fixings, a hefty screw and long plastic wall plug, but you can also use conventional wallplugs and screws, wooden wedges or metal frame ties. With each type, wedge the frame in the opening with wood offcuts so that it is set squarely in place, while the fixings are marked and made.

With screws and plugs, clearance holes must first be drilled in the frame and the hole positions on the wall marked through these. The holes are drilled and plugged and the frame fitted.

Wooden wedges are tapped into slots cut in the mortar joints and the frame nailed to the wedges. Metal frame ties also fit into slots in the joints, being screwed to the frame and mortared in place.

In all cases, you must leave a’/sin gap between the top of the frame and the underside of the lintel to allow for any settlement of the structure.

Leave the packing pieces in place. and fill the gaps at the sides with mortar, leaving it about 1/sin below the level of the frame face. Fill this gap with caulk when the mortar has set. Use caulking to fill the gap between the lintel and frame also. If there is a gap below the frame, fill this with bricks and mortar, splitting the bricks lengthways if necessary.

Make a sub-sill from wood screwed or nailed in place, or a double layer of tiles set on a sloping bed of mortar.

Another way is to cast a concrete sill in situ, making up a wooden formwork “tray” nailed to the wall. The sill should overlap the edge of the bricks by no more than in and you can form a drip channel (to prevent rainwater trickling under the sill) along the bottom edge by pinning a length of waxed cord (sash window cord will do) in the bottom of_ the tray. The top of the lintel should slope downwards so angle the sides for this. Also provide reinforcement by setting steel rods in holes drilled in the brickwork.

Mix the concrete from 4 parts sand: 1 part cement and pour it into the form. Agitate the mix to compact it and remove air bubbles and draw it off level with the top of the form. Leave the concrete for at least 24 hours before removing the foiinwork.

The frame fixing is much simpler to use and is ideal for securing wooden members to masonry. It comprises a hefty screw and a long plastic wallplug.

To use, wedge the frame in its opening and drill holes for the fixings right through it and into the wall. Without removing the frame, tap the plug and screw combination through the frame and into the wall, finally tightening the screw for a secure fixing.

Frame fixings are supplied in various lengths to hold wood thicknesses up to 33/sin. Another development of this is the hammer fixing, which is used in the same way, but set by driving a ridged, countersunk pin into the expanding plug.

Home Repair Tips – Improving The Appearance of Your Home

Filed Under: Do it yourself, Home repair, Redecorating    by: ITC

There are many ways to improve the appearance and value of a home. With the widespread use of drywall two of the most common improvements are:

• Wall trim

• Paneling

Wall trim includes molding and baseboards. Molding comes in various styles and covers the places where wall and floor and where wall and ceiling meet. It is used to cover the rough edges at the ceiling and floor when walls are paneled_ Molding may also cover joints or nails where paneling meets.

Baseboards are high moldings that run along the wall at floor level are often damaged by vacuum cleaners, shoes, toys, and similar objects. Baseboards are usually nailed down lightly so they can be easily removed or replaced.

Paneling comes in 4′ x 8′ sheets and is made of wood, plastic, rock, cork, or some other material. Several years ago paneling was nailed in place. Today much of the new paneling is glued.

Sometimes a panel will come loose. If the loose part is over a stud or joist, it can be nailed down with a colored finishing nail. When the loose section is not over a stud or joist, panel cement can be forced behind the loose panel. Pound the area with a mallet and padded block while the glue is drying to push it tightly against the wall.

The best way to repair a damaged panel is to replace the entire panel. This may be difficult to do if the panel has been glued and nailed. First carefully remove the molding and baseboard. Then use a thin chisel to pry a corner of the panel loose in order to break the panel free from the glue.

Use the old piece as a pattern for cutting the new piece. Remove old glue from the studs or drywall. Apply new panel cement and press the new panel into place. Pound the panel with a mallet and padded block. Drive several small nails into the panel to hold it down while the glue dries. Afterwards, set the nails with a nail set and cover the holes with a putty stick. Large pieces of old paneling may be kept for patchwork.

Baseboards are a type of molding that run along the bottom of a wall next to the floor. They protect the walls and are not difficult to remove or replace.

Adhesives for gluing panels come in tubes and are applied with a calking gun. Move a cloth-covered block over the face of the panel while striking the block with a mallet. This spreads the glue.

Wood trim is used around the ceiling and around the floor especially where wall paneling has been installed.

Modern buildings need continual upkeep and repair. Roofs must withstand harsh weather and keep the inside of the house dry. Doors and windows are subject to frequent use, and they wear out or break. If not kept in good repair, these things can become a nuisance or a more serious problem.
