Renovating in Ridderkerk
What makes renovating in Ridderkerk different
Ridderkerk is made up of old dike villages along the river Noord and the districts built behind them between 1960 and 1990. That difference decides almost everything: a house on the dike has entirely different problems from a terraced home in the polder behind it, even though they stand a few hundred metres apart.
Dike houses in Slikkerveer, Bolnes and Rijsoord
Along the river and the old ribbon developments stand houses built into the dike: the front door at dike level, the rear half a storey lower, and beneath that often a lower level or cellar partly inside the dike. That lower level is usually the reason people call us. It is damp, the floor feels cold, and it never received a proper finish. Rising and penetrating damp cannot be solved with a layer of plaster here: first inject or seal, then insulate and finish. Do it the other way round and the damp is back behind the new wall within a year.
Terraced homes in Drievliet, Het Zand and Slikkerveer-Noord
Behind the dike you find whole streets with the same layout: a narrow kitchen beside the stairs, a closed-off living room and a store room against the rear wall. The two moves that pay off most are opening the kitchen up to the living room and replacing the store room with a full-width extension. In these homes the wall between kitchen and living room is often load-bearing, even at ten centimetres thick, so it needs a structural calculation and usually a steel beam before anything is removed.
Noise from the A15, the A16 and the freight railway
Few places in the region sit as tightly between infrastructure as Ridderkerk. In parts of the town the noise load on the façade is the deciding factor when replacing window frames. Standard high-performance insulating glass keeps heat in very well but does little for sound; bedrooms on the motorway side need asymmetric or laminated glass, heavier draught sealing and acoustic trickle vents. Choose on thermal value alone and the house will be warmer but no quieter.
The loft: dormer or roof extension
The roofs in the expansion districts are shallow, so the loft is usable but too low at the eaves. A full-width dormer adds headroom and daylight and is often permit-free at the rear. If you want a full extra storey you end up with a roof extension, and for that the council does assess the design. We price both options before you choose, together with what each one means for the staircase and the floor loading.
Foundations differ on the dike and in the polder
In the polder behind the dike the houses stand on concrete piles and stay level, while the garden and the terrace slowly settle with the ground. On the dike itself it is often the other way round: shallow foundations in sandier soil, with the house settling rather than the surroundings. For an extension that means two different choices, and we only make that choice after establishing how the existing house is founded.
Window frames and glazing in a 1970s home
Many Ridderkerk homes still have first-generation double glazing or timber frames at the end of their life. Replacing them does more than lower the bill: the draught along the seals disappears, the façade becomes quieter and the indoor climate is noticeably calmer. Combine it with floor insulation and with filling the cavity if it is still empty. Dutch subsidy schemes for insulation change every year; we tell you which ones apply to your situation before you commit.
Common mistakes in Ridderkerk
- Insulating and finishing the damp lower level of a dike house before the damp itself has been stopped.
- Opening the kitchen up to the living room without having the load-bearing wall calculated.
- Choosing glazing on thermal value alone when motorway noise calls for a different build-up.
- Founding an extension without first establishing how the existing house is founded.

Frequently asked questions
Questions about renovating in Ridderkerk
Do you actually work in Ridderkerk, or only in Rotterdam?
Ridderkerk is one of our regular service areas. We are based on Doklaan in Rotterdam-Zuid, about fifteen minutes away via the A16. Our own team runs the projects here, with no hired-in subcontractors, and because the distance is short we can also drop by mid-project to go through something with you.
What can be done about a damp cellar or lower level in a dike house?
First establish where the moisture comes from: rising damp through the masonry, penetrating damp from the ground, or condensation on a cold wall. Rising damp is usually treated by injection, penetrating damp by sealing from the inside, or from the outside if there is room to excavate. Only once the damp has stopped do we insulate, ventilate and finish. The reverse order produces mould within a year.
Does new glazing help against the noise from the motorways?
Yes, but not every type of insulating glass does. Standard high-performance glazing is designed to keep heat in, not to block sound. For façades facing the motorway we use asymmetric or laminated glass, heavier draught sealing and, where needed, acoustic trickle vents. The difference is immediately audible in a bedroom; we specify per façade which build-up is worth it.
How deep can an extension at the back of a Ridderkerk home be?
In the rear garden zone an extension up to four metres deep is often permit-free, provided you stay within the rules on height and on how much of the plot may be built on. On corner plots, where a path runs alongside the house and on the dike plots, that often works out differently because the local zoning plan can contain specific provisions. We check this before designing anything.
Our garden is sinking but the house is not. What does that mean for an extension?
It means the house stands on piles while the garden sits on the clay and peat above them, which slowly compacts. We therefore found a new extension on piles as well, even though shallow foundations are cheaper. If you do not, the extension settles with the garden and pulls away from the rear wall within a few years.
Can you do a dormer and a new bathroom in one project?
That is usually the sensible order. The dormer and the roof insulation create dust and scaffolding; the bathroom needs pipework that often runs through the same floor or duct. Doing everything in one schedule means one round of disruption, one point of contact and no duplicated finishing work.
What does a full renovation in Ridderkerk cost?
That depends on the floor area, on what changes structurally and on how much services work is involved. We visit, go through the house with you and then set out a quotation stating per item what will be done and what it costs. Any additional work is discussed and agreed in writing first, so there are no surprises during the build.
