No lintels windows

Looked down row of houses all the same ie no lintels and sagging. Big job to remove tiles and gutter that could of been avoided. A good post. I have installed for more than 20 years now.

I contacted my installations manager who told me to prop the brickwork above soldier course and carry on, i refused. He has now sent out another team to fit without lintels. This is for the biggest firm in the UK……from up north….. So who will check the job over? They are getting away with this everyday. Hi in December we had triple glazing fitted in our front upstairs and downstairs bay windows.

Since the fitting I have notice the floor boards in the upstairs room directly above the lower window are loose, and there is a crack in the mortar in the brickwork running down from the top window, there was a small crack before the windows were fitted but this has now increased in size. The company did not fit a lintel, I did ask if a lintel would be necessary but they assured there must already be one in place.

I am now … Read more ». To Anglian to bob the builder …. No one can tell me if my lintels need changing. Who is responsible window company or general builder? Feel free to contact me at Keystone Lintels. If you can send me some photos from the outside, one or two close up, and a photo from distance that shows us the view of that side of the house, we should be able to confirm whether a lintel is present.

As I understand it, if new windows are fitted, the fitting company are responcible for the lintel above window. Most doors and windows have a lintel above, meaning that lintel failure is a common problem whether the lintel is made from brick, steel or concrete.

Problems with lintels usually manifest themselves as diagonal cracks or step cracking in the masonry above doors and windows. Change back to the masonry bit if more concrete present or you will just knacker the HSS drill bit! A lintel or lintol is a structural horizontal block that spans the space or opening between two vertical supports. It can be a decorative architectural element, or a combined ornamented structural item. It is often found over portals, doors, windows and fireplaces.

As nouns the difference between lintel and header is that lintel is architecture a horizontal structural beam spanning an opening, such as between the uprights of a door or a window, and which supports the wall above while header is the upper portion of a page or other layout. Provide 9 inch thick for lintel length up to 8 feet. Provide 12 inch thick for those exceeding 8 feet and up to 13 feet.

Provide 3 bars of 10mm dia or 2 bars of 12mm dia both at top and bottom, a total of 4 or 6. Most Mason's avoid rings or Stirrups. Lintels are generally used for load - bearing purposes, but they can also be decorative. The most common materials for lintels are timber, steel and concrete. Steel lintels are generally made from pre-galvanised steel which is cut and either roll-formed or pressed into the required shape.

Purposes of a Lintel Beam to support the walls above the openings like doors, windows, etc. Sometimes lintels are used as a decorative architectural element.

Timber framed buildings also require load bearing support, so do not assume that you do not need lintels for additional support. The first signs of a problem with a lintel are usually cracks in the masonry above the windows and doors. What should you do if you notice cracks above a window or door? Can you repair lintels? Do you need to replace cracked lintels? This guide aims to answer these questions and take you through how to repair lintels with helical spiral bars.

A lintel is a type of structural support used in buildings. They are installed horizontally above opening such as doors and windows to support the load of the structure above. Lintels can be made of bricks, concrete, timber or metal. They provide additional strength at weaker points - if a load-bearing lintel is damaged then it requires attention. When the cracks are above doors and windows, the first step is to look for evidence that the lintel is cracked or blown.

When lintels fail, they often cause vertical cracks to appear in the surrounding masonry. Vertical stepped cracks in the brickwork are therefore the clearest evidence that your lintel has failed. You will generally see vertical cracks appearing diagonally up and in from the top corners of the windows.

Lintels generally bow downwards when they fail, which forces the brickwork up and inwards resulting in cracks and bulging masonry. The most common reasons for lintel failure are faults with the lintel such as the corrosion of the steel. You should consult a structural engineer to rule out a more serious underlying issue. Problems with lintels are often noticed when hardwood windows are being replaced, usually with new uPVC windows. Before installing new windows, contractors should check the condition of the lintels.

Evidence of cracks at this stage is obviously a concern for the homeowner. In these instances the lintel will need to be reinforced or replaced before you remove and install new windows. If you are dealing with a brick flat arch lintels, you can easily carry out lintel repair with helical spiral bars.

These stainless steel bars are bonded into slots above an existing lintel. This imparts load-bearing strength and provides a highly effective repair with minimum disruption. Repairing brick lintels and brick flat arch lintels is easy with helical bars. This is the focus of our guide — you can jump to how to install helical bars to find out more. If your concrete lintel is suffering from horizontal cracks then you need to deal with the crack itself.

This is because water can get into the crack and cause the steel reinforcement within the concrete to rust. The expansion of the rust can cause the concrete to break up.

You should look at different concrete repair products or at replacing the lintel altogether. Over time metal lintels including those made of steel will corrode to some extent.

As the metal corrodes, it expands which causes the render to crack. You will need to fill this crack with a resin injection to protect it.

This should prevent further damage to the lintel. Where timber lintels are used, often in older properties, you are at risk from wood rot wet and dry as well as wood boring beetles. I know i will need them due to the increased load of the roof. Do I need to remove the old wallplate then go from there?

How many courses need to be above the Lintel? Garland Building Projects. If you have the room run a course of bricks on top of the lintel external this gives you room for a damp tray over window, you can also fasten wallplate down better on internal we screw wallplate down into block too as well as strapping you should never screw into a lintel.
