Assembling your own conservatory saves a lot of money. If you haven’t already done so, check it out for yourself. Get quotes for a fully installed conservatory from local firms. Then, get quotes for a conservatory that’s ready for DIY assembly. Don’t be put off by the thought of assembling the conservatory yourself. As long as you plan carefully and build a suitable base, you can do the job using a selection of basic tools.
Check your base is level. If not, adjust it with a fresh coat of concrete. A level base is essential for successful conservatory assembly.
Cut the cills to fit the conservatory base. Most manufacturers supply cills that are slightly longer than the quoted specification. Use diagonal joins at the corners and ensure there is a consistent overhang around the base. Check the manufacturer’s guide at this point. Some suggest you screw the cills into the base after you’ve attached the frames. Others say you should screw the cills into the base first. The exact method depends on the design of the conservatory and the frame fittings.
Place the frames on the cills. The manufacturer supplies fittings that join the frames together. These fittings include corner posts. Use the spirit level to ensure the frames are perfectly vertical. Also check the tops of the frames are perfectly horizontal. Attach the end frames to the wall of your home with screws and masonry plugs. Seal the exterior join with acrylic sealant.
Fix the appropriate conservatory roof rafter to the house wall. Conservatory roofs vary in design. Some slope to the house wall. Others have peaks. Whatever the design, once the wall rafter is in position you can fit the other rafters in place. Use clamps to hold the rafters to the conservatory frames. Screw the rafters into the frames and the wall rafter. Seal the wall rafter against water penetration with a strip of lead sheeting.
Slide the glazing sheets into the roof. Fix in position as recommended by the manufacturer.
Remove any glazing beads and tape from the inside of the frames. Put frame packers and glazing packers onto the frames. Place the glazing units in position. Tap the glazing beads back into place with a rubber-head hammer. Start from the top of each bead and work down. Repeat this installation process for any opaque units along the bottom half of the conservatory.
Install the doors and windows. Once they are in place, adjust them as recommended by the manufacturer. Very often, you adjust the height and position of each door and window by using an Allen key on the hinges.
Attach the guttering brackets to the tops of the frames. Put the guttering in place. Finally, install downpipes.
